ELIAS FRIES AND THE ROMANTIC BIOLOGY
By GUNNAR ERIKSSON
For ret nylig er litteraturen om ELIAS FRIES, der ikke
er særlig stor, blevet beriget med et vægtigt bidrag, GUNNAR ERIKSSON: "ELIAS FRIES och den romantiska biologien". *) Afhandlingen, som er skrevet på svensk for den
filosofiske doktorgrad ved Uppsala Universitet, giver en
yderst fængslende fremstilling af den historiske baggrund
for FRIES' videnskabelige indsats inden for mykologien.
Da afhandlingen næppe er videre kendt uden for Sverige,
aftrykkes med forfatterens tilladelse nedenfor dens fyldige engelske resume.

CHAPTER I.
The German romantic philosophy, represented mainly by SCHELnot only affected art and litterature but also science. Many
scholars, especiaIly biologists, were fascinated by its speculative spirit
and magnificent theory of the world. ELIAS FRIES, the Swedish systematic botanist and mycologist, (1794-1878) gives an example of
this. This is a study of his systematic theories and their dependence
upon the speculative natural philosophy.
Nature was understood by the romantic natural philosophy as a
spiritual entirety, built up of polar forces in constant development.
Every individual part of the univers e mirrored the entirety, constituted a microcosmos, which contained something of the qualities of
the whole. Because the world was spiritual and because man was
also spiritual he could through his powers of reason explore it, and
because the part mirrored the whole the study of one single part
could lead to knowledge of the whole. Therefore the romantic philosophy could promise its supporters · a penetrating knowledge of the
world, an absolute certainty concerning the principles of thought,

which also could appeal to other scientists, especially when their own
research rested on dim principles.
A fieid, which during the century before DARWIN was characterized
to a great extent by a theoreticai uncertainty was the field of systematic botany. As early as during the 18th century many researchers
strived after "the natural system", in which the plants would be
classified according to their "real affinity", not according to external
and artificial grounds. Most botanists had, however, a very dim
idea of the meaning of affinity. They usually did not concern themselves with the phylogenetic affinity, because it was generally
supposed that in our time just as many different species existed as
were created in the beginning. Many scholars identified affinity with
"resemblance", but it was usually vaguely felt that there was a
deeper reason for it, a feeling which was expressed in the theories
about God's plan for creation and in the opinion that the forms were
grouped around types, Platonic ideas, which were reflected in different degrees of clarity by the different individuals. The method of
research was also vague. The supporters of the natural system principally favoured the empirical method, but unconsciously they often
resorted to logical deductions and subjective evaluations.
The romantic biologists were, however, conscious of theory. Their
plant system was built on a thoroughly comtemplated conception of
the world and a determined idea of the scientific method. This is
apparent through an investigation of the German romantic biologist
L. OKEN'S natural system, published in Lehrbuch der N aturphilosophie
in 1810, as well as of C. G. NEES VON ESENBECK'S Handbuch der
Botanik) published in 1820, and System der Pilze und Schwiimme)
published 1817.
CHAPTER II.
The literary romanticism did not appear in Sweden until about
1810. Before this time there was no romanticism in Swedish science.
ELIAS FRIES hardly encountered romanticism until he starte d his
studies at the univers ity in 1811. But even before that time, in the
pre-romantic cultural atmosphere, there were phenomena, which
could facilitate his later acceptance of the romantic philosophy: the
worshipping of nature, and the religious currents such as Herrnhutism and Swedenborgianism, which had Platonic mysticism in
common with romanticism. Natural theology ("physicotheology")
according to whose doctrine the study of nature proved God's omni-
-
3 -
potence, wisdom and goodness, could also be developed into a sincere
philosophy of life, related to romanticism. A few Swedish naturalists
were Swedenborgianists and almost all of the botanists who were
active around the year 1800 were familiar with and supporters of
natural theology. FRIES'S father was a minister, interested in botany,
and had been brought up in WOLFF'S philosophy, where the physicotheological arguments played an important part. During his school
years in Vaxjo (1803-1811) ELIAS FRIES came into contact with
different forms of pre-romanticism.
CHAPTER III.
As a background for FRIES'S activities a survey of the entire
romantic current in Swedish science during the decade 1810 is given.
Because the extreme romanticism in Swedish literature primarily
appeared in Stockholm and Uppsala (in the middle of Sweden) one
could also expect to find romantic science there. It is also true that
there was an interest in speculative scientific research in the literary
romantic circles, primarily in Uppsala, where especially CHR. STENHAMMAR and J. H. WALLMAN, both best known as botanists, are worth
noticing. But also in Lund in the south of Sweden, where FRIES
resided during his univers ity studies, there were representatives in
speculative science. Most important of these is C. A. AGARDH, the
famous algologist, professor of botany from 1812. He was FRIES'S
tea cher and counsellor and it can be conjectured that he was very
important in the growth of FRIES'S romanticism. During FRIES'S three
undergraduate years, 1811-1814, there are, however, still no traces
of romantic influence to be found.
CHAPTER IV.
In 1814 FRIES was appointed docens in botany (without pay) and
he wrote his first scientific papers in systematic botany and phytogeography. He was aIready interested in the natural system. In the
summer 1815 he has visited by WALLMAN. They became friends, and
because W ALLMAN intended to publish a Swedish flora the following
year, FRIES helped him with the fungi. In their correspondence during
the spring 1816 they discussed OKEN'S plant system, and FRIES then
appeared to be a confessor of romanticism- but with some hesitancy.
In the printed flora the philosophic premises were, however, carefully
1*
-4concealed. In 1819 FRIES and CHR. STENHAMMAR began to correspond,
which was of great importance for FRIES' continued development.
Toward the end of 1820 he published the first part of his most famous
work, Systema mycologicum) which is still the basis for the nomenclature of many major groups of fungi. In the introduction of this
work he was extremely speculative, primarily joining OKEN and
NEES VON ESENBECK. The system of fungi is based on a metaphysical
conception of the world: everything is supposedly built on four principles, the elements, the different proportions of which explain all
the differences between the products of nature. The existence of fungi
depends, apart from the elements (primarily water, air and the components of fire: light and heat), on a special force: nisus reproductivus. The proportionally varied influence of these factors is the
basic reason for the different appearences of the fungi's fruit bodies
and conditions in this way the systemization. FRIES distinguishes
four different fruit types and creates therefore four classes of fungi,
each class consisting of four orders, each order with four tribes or
main genera. In each group there is a "center", where the combination of elements, which is typical of the group, appears most
clearly, and "radii" , whose forms border on other groups. All groups
are principally built up the same, and each form in a group reflects
forms in the other groups. The forms within one gro up are connected
by "affinity" , and plants from different groups, which resemble one
another, are connected by "analogy" . These are two very important
conceptions in FRIES' systemization. These terms were adopted by the
English entomologist W. S. MAC LEAY (see his essay, which is mentioned in the reference list*) and were later adopted by several
foreign biologists.
CHAPTER V.
FRIES'S most roman tic period occured during the first half of the
1820's. In letters to his friends he drew up a speculative system over
the whole vegetable king dom in close connection with OKEN'S ideas,
but in 1825, when he published the part which contained the lower
cryptogams (in Systema orbis vegetabilis) ) he had aIready to a great
extent freed himself of his dependence to OKEN. His system was still

which have been lately observed to regulate the natural distribution of
insects and fungi. - Trans. Linnean Soc. of London, vol. 14, pt. 1,
London 1823.
-5built upon a successive quartering, but it did not originate from
OKEN'S theory of the four elements, but was built upon a logical
dichotomy. (An English account of the theories in this thesis is given
by J. LINDLEY; see the reference list. *) In 1820 FRIES was on bad
terms with his former teacher AGARDH. Their personal disagreements
were the background for scientific polemics. Above all they were
disputing the usefulness of logic in systematic botany. AGARDH
expressed an opinion that the logical rules were only human fictions,
FRIES on the other hand vindicated in Systema orbis vegetabilis that
the laws of nature followed the rules of logic. In spite of the fact
that both botanists were romanticists they developed two very different botanical systems.
CHAPTER VI.
FRIES'S next large systematic work was Lichenographia europaea
reformata} published in 1831. Many speculative elements from earlier
works can be found here, but in spite of them there is a new and
more "realistic" spirit in this book. FRIES gives human reason a more
modest place than the empiric observation, and he no longer quotes
any romantic philosophers, but seeks support for his opinions from
FRANCIS BACON and other clas si c, generally accepted authorities. The
development toward this standpoint can be followed in pamphlets
and statements during the period 1825-1831, and can als o to a certain
extent be explained through personal circumstances.
CHAPTER VII.
In 1834 FRIES was appointed professor in Uppsala, where he
remained until his death. In 1835 he published a provincial flora,
Flora scanica} where he for the first time published his system over
the entire vegetable kingdom. In several small dissertations and
other papers he presented the principles for this system, but he never
wrote any collected and detailled representation of it. The system
was still formed on a regular number of plant groups within each
larger group. He also kept his idealistic theory about centers, the
forms of which most clearly reflected the "idea" of the group, and

radii, the forms of which gradually bordered on other groups ; the
theory of the difference between analogy and affinity and the logi cal
classification is als o to be found here. But these theories fight against
more "realistic" ideals, and the demand for empiric observation is
growing stronger. Re no longer refers to a speculative theory of life
as a foundation for his system, and he soon shows an open contempt
for the German "Naturphilosophie" from which his own ideas once
derived.
As early as the 1820's there were traces of biologi cal vitalism in
FRIES: he was of the opinion that life was a special force, higher
than the inorganic forces. This vitalism became very clear in Lichenographia 1831, and occupied a prominent position in his concept of the
world during his years in Uppsala. FRIES'S gro wing hostility toward
speculations is closely connected with vitalism: because life was
something higher, something divine, man could not, even with his
ability to reason, penetrate it; only through a humble study of its
different revelations could it be possibIe to trace its mysteries.
Like many other romantic biologists FRIES had from an early
stage nurtured a doctrine of evolution. Like most romanticists he did
not at first believe that one species could develop into another, but
he thought that all species at one time had been imperfect, and that
they then separately had risen to higher perfection, and had become
more and more similar to the idea which they reflected. During the
1830's and 1840's he began instead to assume that every genus had
existed from the beginning, but that species within the genus could
have developed through ramification from one single basic form.
Re could, however, never accept R. F. LINK'S theory*) from the 1820's
that man evolved from an ape, and he was equally unable to accept
DARWIN'S opinion that all organisms have developed from a few
original forms. As an idealist he was frightened by the materialism
of Darwinism, but he also feared that the botanists would limit the
number of the presently accepted species because of DARWIN'S theory
of heredity.
CHAPTER VIII.
Concerning his general view of nature FRIES could, during his
Uppsala period, be compared with many well known biologists from
the middle of the 19th century. Four German botanists, for whom

kunde. I-II. 1821-1822, Berlin.
-

FRIES especiaIly expressed admiration, are mentioned. In the works
of the descriptive botanist WILHELM KOCH he found the same demands, i. e. that the marks of distinction between the species should
be taken from the living plant, and not from dried out herbarium
specimens, as he himself expressed. In the same way as FRIES
L. REICHENBACH built a system upon the romantic "Naturphilosophie",
developed a doctrine concerning the degrees of metamorphosis of
plants, which FRIES had als o done, and adopted the terms analogy
and affinity. M. SCHLEIDEN, the famous discoverer of the cell as the
fundamental element of construction of plants, also showed, in spite
of his harsh opposition to speculative botany, an inclination for a
philosophical founda tion in science, and confessed tha t there was
something divine in nature. ALEXANDER BRAUN formed an idealistic
and vitalistic physiology of plants, which FRIES held in high esteem.
An idealistic view of nature, free from the worst exaggerations
of romanticism, als o distinguished such prominent researchers as
GEOFFROY ST. HILAffiE, RICHARD OWEN and LOUIS AGASSIZ. In the
general Swedish cultural atmosphere, as well as among contemporary
Swedish scientists, the same spirit was also predominant.
CHAPTER IX.
Finally the relations between FRIES and two of his followers,
N. J. ANDERsSON and H. VON POST, are being examined. ANDERSSON
later adhered to DARWIN and J. D. HOOKER and was perhaps the
first in Sweden to adopt the modern phylo-genetic conception of
affinity. VON POST, skilled botanist, but primarily known as geologist,
shared FRlEs's anti-materialism and carried his idealistic concept of
nature farther in many respects. Until his death FRIES kept his
vision of nature as a harmonious unity, governed by adivine reason,
not by the struggle for existence.

SOME UNUSUAL AGARICS FROM SWEDEN. II.
By T. NATHORST-WINDAHL
SUMMARY.
In a previous pap er (Friesia VI (1961), 291-309) the author has
given descriptions of some unusual Agarics which during the last
years ha ve been collected in the provinces Vastergotland, Halland,
Bohuslan and Varmland in the southwestern part and in the province
Småland in the southern part of Sweden. In the present paper the
author has added further species from the mentioned area. Certain
Agarics collected earlier have als o been identified and some of these
are here reported. The following species are reported for the first
time from Sweden: Mycena alba (BRES.) KUHN. (Omphalia alba
BRES.), M. margaritispora J. E. LANGE, Pluteus Thomsonii (BERK. &
BR.) DENNIS (P. cinereus QuEL.), Rhodophyllus (Eecilia) rusticoides
(GILLET) J. E. LANGE, R. (Leptonia) fulvus (ORTON), (Leptonia
Andrianae BRES. sensu F. H. MøLLER, non BRES.), R. (Nolanea)
araneosus QuEL., R. (Nolanea) xylophilus J. E. LANGE, Hebeloma
pusillum J. E. LANGE, Phaeocollybia lateraria A. H. SMITH, Cortinarius

FR. New records of a number of uncommon species are also given.
The identification of these Agarics were based on my descriptions
of the species in the fresh state. Microscopic examinations of the
dried fruit-bodies were made on crushed mounts in ammoniacal Congo-8-

red, with or without addition of phloxine with ca. 3 % KOH or in
Melzer's reagent as a test for amyloidity. Unfortunately many dried
Agarics preserved in different herbaria are practically useless because
descriptions of the fresh fungi were not made and it is then often
impossible to determine them la ter with security. The collection numbers cited and the photographs are those of the writer.

often upturned at the undulated margin; g i Il s paIe greyish, then
dark er grey or brownish-grey, finally somewhat tinge d pinkish by
13 the spores, distant, broad and adnexed; s t e m 3-5 cm X 3-6 mm,
slightly thickened at the base, striate, covered with dense, greyish or
greyish-brown, shining hairs, sometimes tinged reddish near the base,
hollow, base white-tomentose; f l e s h greyish; s m e Il and t a s t e
none or very faint; veil not observed. - Spores 11-13 X 7-8,.u,
ellipsoid with rather rounded angles; basidia club-shaped, 4-spored;
cheilocystidia inflated fusoid, 40-80 X 11-25,.u, granular, projecting
the basidia about 40,.u.
This fungus is evidently RhodophyZlus araneosus QuEL. as described and figured by L. and H. DøsSING in Friesia (1961). QUELET,
Flore Mycologique de la France etc. (1888) does, however, not mention the conspicuous cheilocystidia, the sometimes reddish tinge near
the base of the stem and sta tes tha t his fungus has narrow gills and
is gro wing in woods of conifers. KURNER & ROMAGNESI, Fl. anal.
(1953) have described the stem as "orne d'une forte houppe de poils
raides, gris ou jaunes, ± rougissantes" which is not in accordance
with the original diagnosis.
The species has not been previously reported from Sweden.

dingy yellowish-brown, apex pallid, smooth; f l e s h thin, sordid. S p o r e s 8-11 X 7-8,.u; cystidia absent.
A good illustration is given by J. E. LANGE, Fl. Agar. Dan. pI. 79 H.
The species is rather uncommon in this area.
l have gathered a species which resembles this fungus but it
differs mainly in ha ving cystidia on the edges of the gills. l think
it may be R. (Leptonia) tenellus FAVRE but prefer to await further
collections to be sure of that.

-15 My fungus agrees very well with the deseription given by BRESADOLA, leon. Mye. pl. 583.1 in having "lamellae ex albide luridis earneo-fuseae" . Aeeording to KUHNER & ROMAGNESI, Flore Anal., 189,
N olanea clandestina as figured by BRESADOLA, leon. Mye. pI. 585,2
is more like N. papillatus BRES. The gills as described by him for
N. clandestina "e griseo-umbrinis purpuraseentes" is, however, in
accordance with the deseription given by FRIES "ex umbrine purpuraseentes" .
The species is also described and figured by KONRAD & MAUBLANC
pl. 180,2 and by J. E. LANGE, Fl. Agar. Dan. pl. 78 D. LANGE writes,
however: "Gills originally dirty brown" whieh does not agree with
BRESADOLA'S diagnosis.

I have ealier (Acta Horti Gotoburgensis (1958) collected this
small Agaric from Rya skog. It is readily recognizable by the more
or less dull violet colour all over; c a p up to 1 cm broad; g i Il s

My description agrees very well with this given by VELENOVSKY,
Ceske Hoube (1920). Characteristic features are the very broad,
distant and thick gills and the blackening of the whole fungus with
age or when handled. This species is growing with Picea as apparent
mycorrhiza partner.
During the season of 1957 while studying Agarics in Femsjo
together with Dr. M. MOSER, Innsbruck, I have obtained a fresh
collect determined by him (n. 6333) and a few days later I myself
have colected material of this characteristic species in the same

The species is well illustrated as Flammula Agardhii by J. E.
LANGE, Fl. Agar. Dan. pI. 122 D. According to him the species is
"only mentioned by Scandinavian authors". It has, however, according
to ORTON (1960) long been known to him from England, 1951 and
1954, and was recorded and described by REm 1955 from the same
country.
The species is apparently rather rare in this country and is
growing under Salix on moist ground, but FRIEs says in Hym. Eur.
it grows "in pratis inter gramina".

first time from this country.

THE APPEARANCE OF ERYSIPHE BETAE
(VAN HA) 'VELTZIEN IN DENMARK
By ARNE JENSEN.
Statens plantepatologiske Forsøg, Lyngby.
SUMMARY
In the extremely hot and dry summer of 1959, Erysiphe betae
(VANHA) WELTZIEN, the powdery mildew of beet, was found for the
first time in Danish beet fields. The attacks were surprisingly widespread and rather severe in the southern parts of the country, especially on the Islands. Even perithecia were found. Since 1959 only
very few and weak attacks have been observed. In the autumn of 1966,
however, numerous perithecia were found which made new investigations possible.
Erysiphe betae (VANHA) WELTZIEN, the powdery mildew of beet,
is normally of importance only in countries with a more continental
climate, e. g. South Russia. Before 1959 the fungus was found in
Denmark only in a glasshouse at the State Plant Pathology Institute
in 1941 and in a single record at Risø in 1958.
In the extremely hot and dry summer of 1959, however, powdery
mildew was found for the first time in Danish beet fields. The attacks
were surprisingly widespread and rather severe in the southern parts
of the country, especially on the Islands. The strong attacks of Beet
yellow virus in 1959 have perhaps favoured the infections of powdery
mildewas mentioned by WIESNER (1960).
S o u r c e s o f i n f e c t i o n for the severe and widespread
attacks of the powdery mildew in beets in 1959 are considered to be
found on the Continent, mainly in the German Democratic Republic.
-
28-

Here, widespread attacks of beet mildew were found in the middle of
July (WIESNER 1960), a month earlier than in Denmark. Southerly
winds had been domina ting for periods of 2-3 days in the beginning
and the end of J une, and in the middle of J uly.
Long distance spread of powdery mildew is formerly suggested
and proved by HERMANSEN (1964), concerning the early infection
with Erysiphe graminis on cereals in Denmark.
Another example of long distance spread, with southerly winds
from the Continent, is given by BUCHWALD (1961) concerning unusual
and widespread attacks of Puccinia graminis on wheat in 1951.
T h e f u n g u s. Beet mildew was first observed in 1902 in Czechoslovakia by VANHA (1903). Unfortunately he named the fungus
Microsphaera betae because of some branching of the appendages.
Later findings of mildew on beets mostly concerned the Oidium form
of the fungus, but JACZEWSKI (1927), MURAVJEV (1928) (both according to BLUMER 1933) and WENZL (1957) have found the perfect
stage and refer it correctly to the genus Erysiphe.
Until1963 the beet mildew usually had been referred to as Erysiphe
communis (WALLR.) LINK':- ) or E. polygoni (DC.) St.-Am. WENZL
(1957) discusses in detail the questions of nomenclature. After a
correspondance with Dr. S. BLUMER, WENZL concluded that the beet
mildew in spite of the branching of the appendages provisionally
must be referred to E. communis.
Based on extensive occurrence of beet mildew in Lebanon in 1962,
WEL'TZIEN (1963) investigated a great number of perithecia. He gives
the combination ETysiphe betae (VANHA) comb. nov., because he finds
the fungus to be different from E. communis} in having branched
appendages and fewer spores per ascus, and different from E. polygoni} in the smaller size of the perithecia and nearly equal numbers
of 2 and 3 spored asci (E. polygoni generally has 3 ascospores in
each ascus).
D a n i s h i n ves t i g a t i o n s. In Denmark, perithecia of the
beet mildew fungus have been found only to a small extent in the
fieId, even in 1959. Perithecia found by CHR. STAPEL, at the end of
September 1959, were investigated by the present author as herbarium specimens embedded in glycerol (JENSEN 1966).
In past years beet mildew has been observed a few times on beet
in the glasshouses at the State Plant Pathology Institute, Lyngby.

In the autumn of 1966 numerous perithecia were found and made it
possibie to renew the investigations and take photographs (figs. 1-5).
The investigations by the present author support that the beet
mildew must be called Erysiphe betae (VAN"HA) WELTZIEN, but there
is a divergence in the number of spores per ascus. WELTZIEN uses the
small number (mostly 2 or 3) of spores as a separating factor. The
findings by the present author show clearly that the number is greater.
Perhaps the number of spores is a question of maturity of the perithecia. WENZL (1957) reports the finding of 2-3 spored asci in October,
but la ter in the year, mostly 3-4 spore d asci could be found.

FNOSI{TICI{ANS (FOMES FOMENTARIUS
(L. EX FR.) KICKX) VARDV AXTVAL I SVERIGE
By INGVAR NORDIN
Institutionen for Systematisk Botanik, UpsaIa
SUMMARY
The Swedish host species of Fomes fomentarius (L. ex FR.)
I{ICKX
The polypore Fomes fomentarius is a widespread and well-known
fungus, which has been dealt with in detail by many authors, for instance BUCHWALD (1930) and JAHN (1966). F. fomentarius appears
abundantly on old beech-trunks on the Continent of Europe and even
in the southernmost parts of Sweden. But in the rest of Sweden (and
outside the area with wild beech) the species is as frequent on birch
as it is on beech. That is to say, the Fagus-limit does not constitute
a boundary for Fomes fomentarius in Sweden. For many fungi which
are closely connected with beech on the Continent of Europe, the
northern limit of this tree in Sweden is a more or less definite boundary
(Trametes gibbosa and OudemansielZa mucida); other fungi show a
marked decrease in frequency (Trametes versicolor and Schizophyllurn commune).
It is a well-known faet, that where Fomes fomentarius occurs, the
fungus sometimes also appears on other substrata than the two mentioned above. In this paper the author lists 12 host-genera with 1"4
species for F. fomentarius in Sweden. Acer platanoides with 18 localities is the only one of these occasional hosts that is fairly common
(see photos!). Corylus and Sorbus are reported as new host-genera.
At the end of the lists of localities there are, after every host,
observations made by the author of other polypores on the same
substratum in Central Sweden (Uppland, Vastmanland and Narke).
Corylus avellana has pro ved a rich substratum at least within the
-
32 -
-
33-
area just mentioned ; all polypores so far known on this host are
listed in the paper.
An asterisk indicates, that the substratum is determined by an
expert, Mr. ERIC ÅBERG, after microscopical investigation.
The author is of the opinion that the occurrence of Fomes fomentarius on different substrata is of no taxonomical value. See als o the
table of measured fruit bodies!
Det ar ej for mycket sagt, att fnosktickan ar en av de allra bast
kanda svamparna i Skandinavien, liksom inom artens hela utbredningsområde. Hartill bidrager sakert svampens ofta allmanna forekomst, fruktkropparnas storlek, deras intressanta utveckling, formoch fargvariationen samt anvandningen i aldre tid i fnoskindustrin.
Det finns en rik litteratur om svampen. Jag vill har referera till
några intressanta artiklar, dels professor BUCHWALD'S arbeten, och
framst det om Fomes fomentarius) naturhistoria, his to ria och anvandning i "Meddelelser" (BUCHWALD 1930), dels till dr. JAHN'S fornamligt illustrerade artikel i "Westfalische Pilzbriefe" (JAHN 1965).
Fomes fomentarius har en vid utbredning i nastan hela Europa,
forekommer (dock mindre rikligt) aven i Nordamerika och ar uppgiven från Asien. Den europeiska sydgransen sammanfaller ungefar
med sydgransen for vildvaxande bok, nordgransen for bjorkens nordgrans. De namnda två lovtraden, Fagus och Betula, ar de huvudsakliga vardarna i Europa; bok inom det nordligt tempererade lovskogsområdet, bjork inom det nordligt tempererade barrskogsområdet.
I Sverige ar boken vild endast i de sydligaste landskapen (men
odlad och forvildad annu i Mellansverige) , medan bjorkar forekommer genom hela landet. Fnosktickan ar allman i alla delar a v Sverige
(i Sydsverige kallas svampen stundom "bokticka"); den overskrider
alltså bo kens nordgrans och upptrader norr darom med oforandrad
frekvens. Detta ar ett intressant fenomen. Ser man på några andra
polyporeer, exempelvis Trametes gibbosa och T. versicolor) vilka liksom Fomes fomentarius ar allmant forekommande på bok i Mellaneuropa, upphor dessa, respektive minskar starkt i frekvens vid bokens
nordgrans. Trametes versicolor) som i stora delar av landet ersatts
av T. zonata) har jag iakttagit på några få lokaler iMellansverige
norr om Malaren, bland annat på odlad Fagus (Uppland, Lot, Fåno;
coll. GUNNAR ERIKSSON). Trametes gibbosa foreligger i Upsala-herbariet från foljande utpostlokaler: Bohuslan, Rodbo, Bjorkåsen, på

Betula) 1943 (NATHORST-WINDAHL 3768-*) samt bland, GardslOsa,
prastgården, 1950 (DAHLGREN) .
I Sverige - liksom overallt inom det område dar Fomes jomentarius forekommer - kan svampen av och till upptrada aven på
andra an de ovannamnda substraten. Avsikten med foreliggande avhandling ar att offentliggora ett ganska omfattande materialover
fnosktickans vardvaxtval. Det mesta harror från mina egna insamlingar under senare år iMellansverige (Uppland, Vastmanland, Narke
etc.). Jag har ave n fortecknat de fynd som ar belagda i våra stora
herbarier, ytterligare material har erhållits från mykologer som tillskrivits angående F. jomentarius) substratval.
I sitt ovannamnda arbete behandlar BUCHWALD in gående fnosktickans vardvaxtval. For Danmark anges sju vardslakten (sammanlagt 9 arter). I en senare notits (BUCHWALD 1934) har tillkommit
annu en art Populus) namligen P. virginiana. BJ0RNEKÆR (1938)
anger Acer pseudoplatanus och Alnus glutinosa som nya vardvaxter
for Danmark. Svampen ar sedan konstaterad har 4 a 5 gånger på
Acer pseudoplatanus) ett par gånger på Alnus glutinosa samt 1 a 2
gånger på Ulmus glabra (BUCHWALD in litt.). De namnda avhandlingarna har gjort mig intresserad for Fomes i Sverige, och enligt
vår nuvarande kannedom ar har motsvarande antal 12 slakten med
tillsammans 14 arter (Carpinus betulus ej medraknad), vilket skall
jamforas med den aktuella danska siffran 9 vardslakten (sammanlagt
12 arter).
Såvitt jag kunnat finn:;t, ar två av dessa sIakten ej alls tidigare
uppgivna som hysande Fomes jomentarius) namligen Corylus och
Sorbus. Som framgår av nedanstående lokallista, hor de fortecknade
vardarna till våra svamprikaste lignoser - med undantag a v Fraxinus. Fnosktickan ar en svår rotsvamp på bok och bjork, på ovriga
trad och buskar saknar den på grund av sin sallsynthet betydelse.
Endast i fråga om Acer platanoides bland de tillfalliga substraten ar
F. jomentarius någotsånar viktig; 18 lokaler ar kanda, och det ar
fråga om alle- och landsvagstrad som infekterats. Nastan samtliga
av dessa observationer har jag gjort under bilfarder, och det har
varit de helt eller delvis doda stammarna som dragit uppmarksamheten till sig - och vid många tillfallen har då fnosktickan avslOjats.
Underhand har for Alnus incana och Populus tremula tillkommit så
många nya lokaler, att F. jomentarius lokalt kan betraktas som en
tamligen viktig rotsvamp, åtminstone på gråal.

I svampsuccessionen på såval upprattstående som liggande stammar av flera olika vardvaxter upptrader Fomes jomentarius och
Fomitopsis pinicoZa samtidigt. Valutvecklade fruktkroppar av de
namnda arterna har iakttagits tillsamrnans på BetuZa (fig. 7), Acer
pZatanoides} AZnus incana} PopuZus tremuZa och Sorbus aucuparia. I
ett nyutkommet arbete, JAHN (1966), behandlas svampsamhallen på
PopuZus tremuZa i Fiby urskog (Uppland, Vange socken). Av intressanta polyporeer som i mindre antal antecknats på liggande, doda
aspstamrnar av måttlig formultningsgrad marks Fomes jomentarius}
dessutom Antrodia moZZis} Fomitopsis pinicoZa} Ganoderma appZanatum och Trametes betuZina.
Eldtickan (PheZZinus igniarius) har ofta kommit att betraktas som
en dubbelgångare till fnosktickan; svårigheterna att skilja de två
åt ar dock betydligt overdrivna. Ph. igniarius (s. lat.) har ett jamfort
med Fomes jomentarius betydligt vidare vardvaxtregister ave n i Sverige; endast i något fall ar fnosktickan den vanligare a v de två.
Det kan var a betydligt svårare att makroskopiskt skilja platttickan (Ganoderma appZanatum) från Fomes jomentarius} sarskilt då
den forstnamnda vaxer på upprattstående stammar av till exempel
Acer pZatanoides (se lokallistan), Quercus etc. Från G. appZanatum
skiljs dock F. jomentarius på forekomst av primordialkarna samt på
sammanhangande ror, hos plattickan ar rorskikten åtskilda av brun
trama. G. appZanatum kan i Sverige upptrada på nastan vilket substrat som helst, från Spiraea till Abies och Pinus. På Brittiska oarna
(exklusive Skottland) har Fomes jomentarius forvaxlats med Ganoderma appZanatum; fnosktickan har visat sig vara en mycket sallsynt
svamp har med endast en saker lokal i Kent (REID & AUSTWICK 1963,
p. 304).
Angående fnosktickans utbredning meddel ar KARSTEN (1882):
"Loftrad, helst bok och bjork, a.". I upplaga 4 av KROK & ALMQUIST"S
kryptogam del (1917) lamnar ROMELL foljande upplysning: "Stamm.
och stubb. av bjork och bok, någon gång aven på ek och lonn, a.".
Som framgår av nedanstående lokallista finns ROMELL'S egna insamlingar på ek och lonn bevarade i Riksmuseets samlingar (S). I senaste upplagan av kryptogarnfloran (1962) har passusen om ek och
16nn fått utgå.

dessa ar lind och hagg ej kanda som vardtrad i Sverige.
De flesta kompletteringarna, bland annat samtliga nya lokaler på

allmant odlad som vård- och alletrad. Listan over forekomster av
Fomes jomentarius på A. platanoides från denna trakt kommer att

Hosten 1967 har jag haft tillfalle att besoka ett område vid Flinesjon iDalarna, tillhorigt Stjernsunds skogsforvaltning, dar lovskogen
dodats genom fickning. De doende traden hade infekterats av Fomes

de kaIa bjorkstammarna inom stora områden. Salix caprea antecknades aven som vardvaxt, och det ar mycket troligt att aven andra
lovtrad var infekterade av fnosktickan. Metoden med fickning anvands inom storskogsbruket på många håll. Resultatet kan bli som
på den namnda lokalen en kolossal uppblomstring av vissa rotsvamp ar, och framst då Fomes jomentarius. På bjorkstammar som
blivit svedda av eld upptradde darjamte Fomitopsis pinicola) Pycnoporus cinnabarinus etc.
Bland de polyporeer som - forutom Fomes jomentarius - antraffats på Corylus avellana marks den nyfunna Phetlinus robustus
(en lokal iOstergotland) . I och med f yndet foreligger nu två for
Quercus och Corylus gemensamma och exklusiva tickor, namligen
Coriolellus campestris och Phellinus robustus. Ektickans huvudform

på Corylus i Westfalen (JAHN in litt.). Den av mig funna kollekten
utgors av f. resupinatus BOURD. & GALZIN, helt resupinat på upprattstående, doda hasselstammar. I brottet hade fruktkropparna en for

PHYSODERl\1A GERHARDTIl SCHROET.
ON GL YCERIA MAXIMA (HARTM.) HOLMBL.
IN DENMARI{
By J 0RGEN KOCH.
Contribution No. 79 from the Department of Plant Pathology,
The Royal Veterinary and Agricultural College, Copenhagen.
SUMMARY
Physoderma gerhardtii SCHROET. is reported to have been found
on Glyceria maxima in Denmark. The germination of the resting
sporangia is described in detail. Preliminary infection experiments
with Alopecurus pratensis) Baldingera arundinacea) Dactylis glomerata) Glyceria fluitans and Glyceria maxima resulted in infections on
the latter species only.
During an excursion on 11th June 1966 to Utterslev Bog in the
northern environs of Copenhagen, the author noted that the lowest
leaves of a population of Glyceria maxima bore from few to many
rustlike spots which, af ter microscopic examination, were found to be
infections of Physoderma gerhardtii SCHROET. Since no Physoderma
species have previously been recorded on grasses in Denmark and
many species within this interesting genus are in general rare, and
therefore not very intensively investigated, some observations concerning this discovery are reported here.
The population of Glyceria maxima was growing in a flat depression, the bottom of which was so wet and spongy that is was not
possibie to venture there in shoes. The population was dense and

covered an area of 40 X 20 m. In the lowest-lying parts 90 % of the
plants were infected, while slightly high er up only 20 % showed signs
of infection. With a further rise of approximately 5 cm the infection
died out completely. Normally only the lowest leaf was infected,
although occasional plants were found with two infected leaves.
The infection spots consisted of a brown-violet centre surrounded
by a yellowish zone. They occurred singly, in larger aggregates, or
in shorter to longer single-rowed stripes, and were 1,5-4 mm in lenght
and 1-2 mm in breadth. Three weeks la ter the single infection spots
were found to meas ure up to 9 mm in length. The spots were, in
general, larger when they occurred singly, and small where numerous
infections were sited on a small area of leaf (fig. 1). This is, without

doubt, the same observation which led KRIEGER (MINDEN 1911), on
the same host plant, to differentiate between a major and a minor
form. The difference in size of the infection spots in the Danish material is considered, however, to be determined by the relative absence
or abundance of nutrients for the individual mycelia, and not to be
due to a difference in genotype.
In each cell 1-3 resting sporangia were observed. These frequentley had taken the shape of the cell and measured 19.5-41.1 X 15.6-31.2p,
with an average of 26.6 X 21.5 p (50 spores). The walls of the resting
sporangia were violet in colour, approximately 1 p thick, and smooth.
Rhizomycelium and haustoria from resting sporangia and turbinate
cells were found.
Since the germination process was not known (KARLING 1950),
attempts were made to germinate resting sporangia in suspended
drops of glass-distilled water. This method proved practicable so
far as spores germinated after two days at room temperature and
released zoospores. Upon germination an endosporangium was produced which pushed up a circular cup-shaped lid from the broader
side of the epispore. A part of the endospore, as a rule still carrying
the lid, was then extruded, taking the shape of a truncate d cone (fig.

2a). At the same time the cytoplasm was observed to become increasingly differentiated. Highly refractive droplets appeared, and the
faint outlines of few zoospores could be vagueley distinguished. As
a presage of the final germination phase, bacteria in the neighbourhood of the resting sporangium suddenly became activated, and
accumulated around the sporangium (fig. 2b), their swimming speed
being greatly increased. The sporangium was finally observed to lie
in a halo of higly-activated bacteria. After 5-10 seconds the bacterial
activity returned to normal again. No visible change was observed
in the germinating spore, but aseeretion was undoubtly emitted,
either through apical fission of the endospore or by diffusion. After
this presage 5-15 minutes passed before the final phase of germination commeneed. The cytoplasm began to flow slowly out of the apex
of the endospore, the speed gradually increasing. Outside in the
water the cytoplasm contraeted to form a segmented vesicle which
appeared well defined for approximately 1 second (fig. 2c). This
vesicle disrupted abruptly due to the independent movements of the
individual zoospores, which af ter a few seconds swam away. At the
apex of the empty endospores a circular opening with frayed edges
could often be seen. The opening was of approximately the same size

THE CONIDIAL STAGE OF COCHLIOBOLUS
SATIVUS AS A POTENTIAL PATHOGEN
AND AS CAUSE OF A DISGUISED
DISEASE IN CEREALS IN DEN MARK
By J. P. SKOU
Agricultural Research Department, Danish Atomic Energy Commission
Research Establishment Risa, Roskilde, Denmark
SUMMARY
CochZiobolus sativus (ITO et KURIE.) DRECHSLER*) stat. conid. has
been in Denmark for a long time. The fungus is common on grains of
cereals, while it is very sparsely reported from gro wing plants. The
author has occasionally isolated the fungus from the roots and stem
base of cereals during his work to isolate other pathogens (Ophiobolus
graminis and Cercosporella herpotrichoides) .
Investigations show that the Danish isolates have the same properties as isolates from other regions and therefore are at least
potential pathogens, able to cause diseases when and where the inoculum potential is great enough. But as the symptoms (root rot, eye
spots) caused by C. sativus on the plants are rather unspecific, they
may be disguised under symptoms of the severe cereal pathogens
O. graminis and C. herpotrichoides. In addition the fungus may cause
leaf spots. An intense dark brown colour is characteristic of all the
symptoms, no matter on what part of the plants they occur.
It was found tha t both the toxin and the fungus diminished the
yield.
Weibulls Starke wheat and Weibulls Ingrid barley were affected
by both the toxin and the fungus, Petkus II rye nearly exc1usively
and SvalOf Stål oats insignificantly by the toxin only, and Carlsberg

II barley mainly but not exclusively by the fungus. An effect on the
germination of wheat and rye was observed.
Ingrid barley was found significantly more susceptible to C. sativus than Carlsberg II as measured by symptoms and dry-matter yield
in seedling tests.
The difference between the isolates manifests itself mainly in the
amount of toxin produced. The attacks were increased by adding meal
of wheat grains to the inoculum medium.
1. INTRODUCTION
Cochliobolus sativus (ITo et KURIE.) DRECHSLER->:- ) stat. conid. (syn.
Helmisporium ** ) sativum PAMM., KING et BAKKE; Bipolaris sorokiniana
(SACC. in SOROK.) SHOEMAKER) is a common, variable and polyphagous pathogen on cereals and grasses in the main part of the graingrowing areas of the world. The attacks seem to be most severe in
the U.S.A. and Canada, where the fungus occasionally caus~s great
losses in barley and wheat.
Occurrence of C. sativus is frequently reported from different
parts of Europe; however, the fungus seems les s significant in this
region, though perhaps more than hitherto assumed (KOLK 1966,
LANGE-DE LA CAMP 1958, MULLER 1956, DE TEMPE 1964). The reports
from the northern part of Europe, including Denmark (see below)
refer nearly exclusively to occurrence on and in the grains of cereals
(FRITZ 1965, 1966, KOLK 1966, DE TEMPE 1964), on which the fungus
may be considered common. In spite of this there are very few reports
about attacks on the plants (LANGE-DE LA CAMP 1958). These apparently conflicting facts are surprising: as the inoculum must come
from a source and as it is an accepted faet that C. sativus has little
or no competitive saprophytic ability in soil (GARRETT 1963, and
others), the fungus must, at least rather frequently, occur and propagate on susceptible plants.
One may then ask whether attacks by Cochliobolus sativus in this
region is a disease disguised under symptoms of other diseases,
whether it is a potential pathogen able to cause attacks on cereals
when and where the inoculum potential becomes great enough (GARRETT 1960), or whether its significance is less than its occurrence on
* ) sensu D ASTUR (1942).
According to HUGHES (1958) and SHOEMAKER (1959) H elminthosporium LINK ex PERS. (1822) is an illeg itimate orthographic variant of
Helmisporium LINK (1809), validated by S. F. GRAY (1821).

the grains appears to show, because of a lower pathogenicity or more
saprophytic strains than in areas where severe attacks on all parts
of the plants are known to occur.
The reason for asking these questions is that C. sativus sometimes
came out when the author tried to isolate Ophiobolus graminis SACC.
from roots of cereals and CercosporeZZa herpotrichoides FRON from
their stem base.
n is worth knowing the answers as well from the plant pathology
point of view as for experiments concerned with breeding for resistance to diseases producing interchangeable symptoms.
Results of experiments for the elucidation of some of the questions
are reported below.
2. C O C H L I O B O L U S S A T I V U S A N D I T S O C C U R E N C E
IN DENMARK
The dark brown to black colonies of C. sativus stat. conid. with
the brown phaeophragmic conidia are placed in the form family Dematiaceae. The size, and the number of cells in the conidia are very
variable (cf. e. g. ANDERSEN 1954, DICKSON 1956, DRECHSLER 1923).
As aiready shown by DRECHSLER (1923) , this is due, at least in part,
-
60-
to the hosts or substra tes (Fig. 1). Therefore the size of the conidia
given in the literature is of limited value if it is not supplemented
with a specification of host or substrate, and even then the conidia
are not uniform from isolate to isolate.
A more reliable characteristic is the strictly bipolar (or polar)
germination of the conidia (DRECHSLER 1934, RAPILLY 1964, SHOEMAKER 1969), compare Fig. 2.
In 1963 (ANDERSEN 1963 a, b) Cochliobolus sativus was mentioned
for the first time in the Danish literature on plant pathology. A few
years later a severe attack was observed in an experiment with
sowing seeds of Lolium perenne L. infected by H elmisporium catenarium DRECHSLER (ANDERSEN 1969). With barley as cover crop the
attack by H. catenarium was strongly restrieted, while an attack by
C. sativus increased from 40 to 76 % of the plants. ANDERSEN considered it prom o te d by the barley.
Recently an examination of 100 seed samples of barley showed
62 samples to be infected by C. sativus with a variation from 1 to
6 % infected grains (JØRGENSEN 1966).
All these observa tions were made primarily on grains or seeds
and only sparcely on the gro wing plants (L. perenne) see above).
The first discovery in Denmark, however, was made on roots and
stem base of diseased barley plants by C. A. JØRGENSEN as early as
1930. H. H. HOLME HANSEN, agricultural adviser, took the plants
from a diseased spot in a barley field at Sæbyholm, Lolland, and
forwarded them to the Government Plant Pathology Institute,
Lyngby, with the remark that the cause was possibly drought. This
isolate of C. sativus together with drawings of the conidiophores
and of the conidia with or without the bipolar germination (see
above and Fig. 2) and an isolate of the fungus received from Professor
J. J. CHRISTENSEN, Univers ity of Minnesota, in 1930, still exist (in
dry condition) in the herbarium of C. A. JØRGENSEN. The isolates
made by the present author are found identical with those of this
herbarium.
As noted in the introduetion, the author has now and then isolated
C. sativus from both roots and straw.
On the basis of the above it may be stated that the fungus has
been in Denmark for a long time and that it is, perhaps, as common
here as in our adjacent countries, and further that it is sparsely
reported on growing plants (cf. ANDERsEN 1969, LANGE-DE LA CAMP
1968).

3. EXPERIMENTAL
a. Material and Methods.
Two isolates of Cochliobolus sativus were used in the experiments.
Both were isolated as mycelium from black-coloured roots of barley
in 1964 by the method of DAVIES (1936) ; No. 600 from an apparently
healthy corp at Riso, Zealand and No. 617 from a crop with severe
root rot at Engbjerggård, Snoldelev, Zealand. From its general
appearance the attack was thought to be caused by Ophiobolus graminis} the take-all fungus.
The isolates were grown on malt extract agar or on a medium
containing wheat straw extract and glycine. All transfers were made
with a rather large amount of mycelium and conidia in an attempt to
keep possible special characteristics.
As host plants Weibulls Starke wheat, Petkus II (2n) rye, Carlsberg II barley, Weibulls Ingrid barley, and SvalOf Stål oats were
used. The grains were surface sterilized with 1 % NaClO and soaked
overnight on moistened filter paper before sowing.
The following medium was used for preparing the inoculum: K-soil
(standardized commercial peat-rich soil inriched by clay and fertilizer) mixed with wheat-straw meal (or meal of wheat straw + grains)
-
62-
in the ratio of 30: 5. Af ter autoclaving at 1 kg per cm2 (15 Ib per
square inch) for four hours in portions of ca. 50 g in 250-300 ml glass
jars, 20 ml of a solution of 4 % glucose and 0.25 % glycine was added
to each jar. The mixture, having a water holding capacity of 300-320 g
water per 100 g, was moistened to ca. 70 % saturation.
From a dens e growth of C. sativus) ca. 2 cm2 agar with mycelium
and conidia was split up and spread on the surface of the medium.
After incubation at ro om temperature for a month the K-soil medium
was completely interwoven with the mycelium and ready for use.
The experiments (seedling tests) were performed in the greenhouse at 15-25° C. Plastic pots (diam. 15 cm) were filled three
quarters with untreated Perlite, upon which the inoculum was placed,
one glass for each pot. An autoclaved, uninoculated medium served
as control (see further the third series of experiments). Then 25
grains were sown, and the whole was covered with ca. 1.5 cm steamboiled rough sand. During the growth the plants were fertilized with
a standard nutrient solution (HEWITT 1952).
Three-four weeks after sowing - depending on the temperature the experiments were stoppe d ; the roots were washed free of soil
and Perlite and examined for symptoms in accordance with the following scale:
o = roots without symptoms;
1 = 0-10 %;
2 = 10-25 %;
3 = 25-50 %;
4 = 50-75 % and
5 = 75-100 % discoloured root-mass.
The dry-matter production was determined in root and top separately; compensation for lack of plants was made so that the results
given are for 25 plants where not otherwise stated.
The coefficient of variation was always greater for roots than
for tops. In the tables, roots and tops are added up. Significant effect
always means significance at the 5 % confidence limit or better.
For the induction of symptoms on the upper parts of the plants,
Starke wheat, Carlsberg II and Ingrid barley were sprayed with a
suspension of conidia at the three-four-Ieaf stage and then placed in
a humid atmosphere at ca. 20 ° C for three weeks.
Finally the isolates of the fungus were examined for toxin production and for toxin-induced symptoms by the method of GAYED
(1961) .

b. Results of infectio n experim ents.
1. Experim ents with direct compar ison of sympto ms
caused by
Cochlio bolus sativus and Ophiobo lus gTamini s.
The aim of the first series of infectio n experim ents was to
see
whethe r the isolate s of C. sativus were able to cause root sympto
ms
interch angeab le with those of O. graminis) and whethe r they
were
able to diminis h the dry-ma tter yield.
In table 1 the effects of the two C. sativus isolate s are compar
ed
directly with the averag e effect of some O. gramin is isolates
and
with the most aggress ive isolate of o. gramin is (No. 504) separat
ely.
No. 504 is se en to cause a severe loss in yield. On an averag
e of all
the O. gramin is isolates , the yield is diminis hed signific antly.
Also
the random isolate s of C. sativus cause a signific ant loss
of drymatter. They clearly differ in effect. No. 500 has a signific ant
effect
only on Starke wheat, while No. 517 causes a signific ant loss
in both
Starke wheat, Carlsbe rg II barley and Petkus II rye. The points
for
discolo ured roots are in agreem ent with the loss in yield. It is
worth
noting that No. 517 diminis hes the yield in rye withou t appreci
able
discolo ura tion of the roots.
A compar ison of the root sympto ms caused by Ophiobolus
graminis and by Cochliobolus sativus showed that it would be difficu
lt or
imposs ible to disting uish betwee n the two disease s on the
basis of
the root sympto ms alone. The most appare nt differe nce to the
naked
eye is that roots attacke d by O. gramin is appear more or less
blackis h
while those attacke d by C. sativus are dark browni sh. Less
conspicuous is the fact that roots attacke d by C. sativus have a
greater
tendenc y to collaps e in belts and then may become somew hat
stubby .
2. Infectio n experim ents with all cereal species grown in Denmar
k.
In a second series (table 2) the two isolates were inocula ted
on
the four cereal species grown in Denma rk, inc1uding two varietie
s of
barley.
As in the first series, a substan tial differe nce is seen betwee
n
the two isolates , No. 517 being the most aggress ive. Barley and
wheat
are most strongl y affecte d. Isolate No. 517 diminis hes the dry-ma
tter
yield of Ingrid barley signific antly more than that of Carlsbe
rg II
barley (Fig. 3). LOISELLE (1962) came to the same result by a
related
method (HAMIL TON et al. 1960).

The points score for discoloured roots follows the decrease in
dry-naatter yield.
The oats are only insignificantly affected by both isolates and,
like the rye (by No. 517), without discolouration on the roots.
3. The effect of autoclaved inoculum compared
with that of living inoculum.
In a third series (table 3) the effect of autoclaved (20 nain. at
1 kg per cna 2 ) inoculuna was conapared with that of living inoculuna in
order to see whether the isolates produced a thernaostable toxin-X- ) as
pointed out by LUDWIG et al. (1956). In this series, too, the effect
of a larger anaount of easily deconaposable organic naatter in the
inoculuna naediuna (naediuna 2) was tried, but in wheat only.
No difference was denaonstrated between uninoculated autoclaved
control (naediuna 1) and untreated raw K-soil.
The autoclaved inocula proved toxic, which naust be ascribed to
the previous growth of the isolates of C. sativus. No. 500, autocl.,
thus significantly dinainished the dry-naatter production of Ingrid
barley, but not that of Carlsberg II barley and Starke wheat. No. 517,
autocl., on the other hand, showed a strong effect on Starke wheat
(both naedia) and on Petkus II rye as well as on Ingrid barley, but
not on Carlsberg II barley and Stål oats. Autoclaved inocula gave no
or practically no synaptonas on the roots.
The living inocula of both isolates had a stronger effect than the
autoclaved inocula, due to the fungus and to the toxic substance produced before and during the experinaent. In wheat and rye both
isolates caused a significant decrease in the nunaber of plants per pot.
On conapensation for this, the loss caused by No. 500 disappeared on
naediuna 1, in both wheat and rye, but not on naediuna 2 (wheat).
The conapensation could not elinainate the effect of No. 517. In
barley and oats there was no effect on the nunaber of plants. These
results are in agreenaent with those of HORRICKS (1963), who found
wheat generally naore susceptible to toxic substances in soil than
*)
The significance of the toxin produced by Oochliobolus sativus was
first demonstrated by LUDWIG (1957). In 1961 DE MAYO et al. isolated
and characterized the toxin as an unsaturated aliphatic dialdehyde of
terpenoid structure with the formula C15H220 2. In 1963 COREY & NOZOE
made the total synthesis and were able to provide the absolute stereochemistry of the toxin. It is named helminthosporal.

barley and oats; confer further GREANEY & MACHACEK (1946). Apart
from this, the effect of the living inoculum agreed with that observed
in the two previous series.
On medium 2 there was a substantially greater effect on both
dry-matter yield and symptoms than on medium 1. This is probably
due to a heavier growth of the fungi on medium 2 together with an
increased production of the toxin. The significantly smaller drymatter yield of the controIon medium 2 as compared with the control
on medium 1 is not due to a toxic effect of the medium, but rather
to a very rapid growth of random microorganisms on the more easily
decomposable medium 2 immediately after sowing (author unpubl.;
cf. further LUDWIG et al. 1956, HORRICKS 1963).
4. Demonstration of toxin production on liquid media.
Supplementary investigations showed that the toxin production
on liquid media (method of GAYED 1961) is easily demonstrable (Fig.
4). Af ter the fungus has been grown on the medium for about one
month, whole leaves or pieces of leaves are placed in the filtered

medium for 48 hours. By this time necrotic spots of varying size
develop. The small spots are dark brown while the greater ones have
a paIe dea d centre surrounded by an intensely brown halo.
H was thus possible, both by inoculation of seedlings and by growing the fungi on an artificial medium, to demonstrate the production
and effect of the crude toxin.
5. Spraying of young plants of barley and wheat with canidia af
Cochliobolus sativus.
Finally barley and wheat plants at the three-four-Ieaf stage were
spraye d with a suspension of conidia in order to see if they could
produce symptoms on the upper part of the plants. AIready four
days after inoculation severe symptoms occurred on barley leaves at
20 ° C in a humid atmosphere (Fig. 5). At this time only faint symptoms were seen on wheat where attacks develop more slowly than on
barley, but may become severe.
-
71 -
The more or less necrotic spots are dark brown and oval to fusiform, on the lea f edge greater and less uniform, and surrounded by
a yellowish green halo which may spread to greater areas of the
leaves so tha t they a ttain asenescent colour (Fig. 5). The coleoptile
seems especially susceptible. These findings agre e with LANGE-DE LA
CAMP (1958), LUDWIG (1960), and MULLER (1956). In three-four
weeks the attacked leaves may wilt so that the plants become somewhat defoliated - the defoliation beginning at the lower part. Secondary infections occurred on la ter developing leaves. On the lower
leaf sheats near the stem base, oblong brown spots developed, which,
although atypical, may be interchangeable with symptoms of Cercosporella herpotrichoides under ' field conditions. According to
LANGE-DE LA CAMP (1958) these symptoms may become real eyespots.
4. D I S C U S S ION
The fact that Cochliobolus sativus in Denmark is nearly exclusi vely known from grains and seeds of cereals and grasses may ha ve
several causes. First of all the climatic and edaphic factors may play
a part as it is known that severe attacks on all parts of the plants
occur primarily in countries with warm and dry summers and that
the fungus prefers soils of low fertility (BUTLER 1959, GARRETT
1966). For these reasons the propagation may be so slow and the
attacks so late in this country that symptoms on the upper parts of
the plants may be hidden under senescent or ripenning colours, which
can be promote d by the fungus (cf. e.g. GARRETT 1963).
However, as shown in infection experiments, the symptoms of
C. sativus may als o occur disguised under symptoms of Ophiobolus
graminis and CercosporelZa herpotrichoides. It might be from plants
thus attacked that the grains are infected (LANGE-DE LA CAMP 1958,
MULLER 1956, DE TAMPE 1964).
The most essential difference between the two isolates used in
the experiments seems to be in the amount of toxin produced. Greater
differences are thought to occur in the field (cf. e.g. WOOD 1962).
The difference in susceptibility found between the species and
varieties of cereals tried seems determined by one or both of two
agents, namely the toxin and the fungus. Starke wheat and Ingrid
barley are susceptible to both the fungus and the toxin. In these

experiments at least, Petkus II rye nearly exclusively and Stål oats
exclusively but insignificantly are affected by the toxin. Carlsberg II
barley is mainly attacked by the fungus. Thus, in agreement with
LUDWIG (1957), the toxin may affect all the four species.
The results of the experiments and the fact that nobody knows
the distribution and severity of attacks by CochZioboZus sativus in
Danish agriculture point to the expediency of searching for an elucidation of its importance. This is especially imperative for an exact
diagnose in field experiments with breeding for resistance to root
rot of cereals where even a small attack can make troubles.
ADDENDUM
In the summer of 1967, two months after the manuscript was forwarded, a rather severe spontaneous attack of CochZioboZus sativus
was observed and identified as the primary cause of a diseased crop
for the first time in Denmark.
The attack covere d about 5,000 m 2 in a barley field at Hanehøj,
Tjæreby (near Roskilde), Zealand (Fig. 6).

From left to right increasing degree of attack, the firs t pl an t to the left being h ea lthy. The attacked
roots an d straw base vary in co lour from paie greyis h ( diffuse necro tic areas - sometimes with
brown h alos like the eyespots, see plants 2 and 4 fro m the left) to uniform dark brown .
The conditions for an attack were excellent: The summer was
warm and dry and the soil light and sandy. The barley was secondcrop spring barley. In the time between the two crops there were
pits of narcissus bulbs covered with barley straw on the area. After
the pits had been removed most of the straw was burned, but some
was ploughed down and may have brought about some nitrogen deficiency here and there (compare e.g. BUTLER 1959, GARRETT 1966).
Of course the damage was aggravated by the drought, but neither
this nor a possibIe deficiency in nitrogen could be primarily responsibIe for it.
The attack was found on straw, roots (Fig. 7) and kerneIs, from
which the fungus could be isolated very eas ily after a surface sterilization. AIso the characteristic brown spots on leaves (compare Fig. 5)
were observed - mainly on young leaves of a regrowth brought forth
after the rain.

NY LITTERATUR
Roger Heim: Les champignons toxiques et hallucinogenes. - 327 s .
N. Boubee & Cie, Paris 1963. - Pris : 42 F + tillæg.
Den første del af ROGER HEIlVI'S bog er en interessant sammenfatning
af, delvis også supplering af vor hidtidige viden om giftsvampe, hvorom
der er udgivet mange bøger. Af størst værdi er bogens anden del: de hallucinogene svampe.
Forf. giver i indledningen et historisk tilbageblik over svampeforgiftninger. Talrige steninskriptioner og rester af de schweiziske pælebygninger viser, at svampe i årtusinder har været kendt og anvendt som
menneskeføde. Det er let at genkende Velsmagende Mælkehat (Lactarius
deliciosus) på kalkmalerierne i Herculanum. De romerske aristokrater ansatte tidligere plebejer til at samle svampe. SENECA sagde herom: "Du
store Gud! Hvor folk dog arbejder bare for mavens skyld!" Hvor der er
svampeforbrug, forekommer også forgiftninger. Ud over rene forgiftningsulykker kendes også flere overlagte kriminelle tilfælde; blandt disse
er det mest berygtede: kejser CLA UDlUS' død. AGRIPPIN A, den foregående
kejser CALIGULA'S søster, var utålmodig efter, at hendes søn, NERO, skulle
bestige tronen. Hun sørgede for ved hjælp af sine hoffolk, at en ret af
den fine Kejserfluesvamp (Amanita caesarea) J som kejseren skulle spise,
blev gennemvædet med saft udpresset af Løgknoldet Fluesvamp (Amanita
phalloides) .
Efter det underholdende historiske kapitel følger en datarig redegørelse over svampeforgiftninger i tropiske og subtropiske egne. Beskrivelsen af de forskellige sygdomsbilleder (syndromer) kan især regne med
speciallægers og toxikologers opmærksomhed. En gennemgang af de talrige arter og ikke mindst af de arter, der betragtes som farlige - indbefattet nogle mikroskopiske svampe, f. eks. Monilia sitophila - er også
fra et rent mykologisk synspunkt interessant. Det lille kapitel om de "rehabiliterede" arter byder sandsynligvis for manges vedkommende på overraskelser. Volvaria gloiocephala og dens var. speciosa er spiselige lige som
alle de andre arter inden for slægten. Den pågældende art sælges i øvrigt
på Nord-Portugals frugtmarkeder. Amanita citrina (A. mappa) betragtedes længe som værende lige så farlig, ja dødsensfarlig som A. phalloides.
Bønderne i Cevennerne spiser A. citrinaJ og CHAUVIN påviste eksperimentelt dens uskadelighed (sml. BUCHWALD i "Friesia" 2: 243-263, 1943).
Blandt de hallucinogene svampe spiller Rød Fluesvamp (A mani ta
muscaria) en vigtig rolle. En gastro-intestinal forgiftning fremkalder ved
dens toxin, muscarin, frem for alt en tilstand af vildelse, beruselse, eventuelt sansepirring eller hallucinationer. Forf. fortæller - idet han nævner
R. G. & V. P. WASSON (1957) som kilde - , at svenske soldater fra Varmland-regimentet i begyndelsen af det 19. århundrede var helt ophidsede,
ja bogstavelig talt rasende som følge af indtagelse af A. muscaria J før de
gik i kampen. Det gjorde de herefter med skummende mund, og deres
dumdristighed kendte ingen grænser (sml. POUL THORSEN i "Friesia" 3:
333-351, 1949).

Amerikanske stenstatuetter af svamp e.
Fra venstre til højre: Statuette med en skrubtudse fra sidste del af den
præklassiske periode 500 f. Kr.-200 e. Kr., Mexico, Guatemala; med en
jaguar fra epoken Miraflores 1000-500 f. Kr., Kaminaljuya, Guatemala;
med en menneskelig figur, sidste del af den præklassiske periode, Guatemala.
Indianerne lige fra Mexico til Peru spiste ofte hallucinogene svampe
ved deres religiøse-kultiske fester. Stenstatuetter af skrubtudser, jaguarer
og mandsskikkelser - fra hvis hoveder fremvokser en hatsvamp - vidner
om de gamles kendskab til denne dæmoniske narkomani. New-Guineas's
urbefolkning så vel som Sibiriens samojeder anvender den dag i dag giftige svampe som aphrodisiaca. Ved en mængde eksempler gennemgås de
enkelte hallucinogene svampeslægters psykiske virkning, først og fremmest Psilocybe) som rummer mange hallucinogene arter, dernæst S trop haria) Panaeoltts) Amanita m. fl.
Et særligt kapitel beskæftiger sig med ergotismens (meldrøjer-forgiftning) historie og med kemien af de alkaloider, der fremkalder denne frygtede forgiftning, så som ergotamin, ergosin, ergokryptin, ergocornin og
det i vore dage så ofte omtalte LSD 25.
Forf., den fremragende mykolog, behandler med elegant sikkerhed
de til emnet hørende arkæologiske, kulturhistoriske, etnografiske, biokemiske, toxikologiske og psykopatologiske enkeltheder. - Det er en bog langt
ud over det sædvanlige.

Som tillæg til N ova Hedwigia XI er kommet det første hefte af en

af mikroskopiske karakterer og farvetavler med akvareller udført af forfatteren selv efter frisk materiale. Hovedvægten tænkes lagt på Agaricales
(hatsvampordenen), men også nogle svampe fra Aphyllophorales (poresvampordenen) skulle medtages. I foreliggende hefte er beskrevet 4 Boletus-arter, 1 Laccaria-art, 4 Lepiota-arter, 1 A manita-art og 1 Stropharia-

skulle med sine omhyggelige beskrivelser af svampe, hvorom det ellers kan
være vanskeligt at finde publikationer, kunne blive en værdifuld støtte
ikke blot for fagmykologer, men også for særligt interesserede amatørmykologer. Det er ikke nødvendigt at abonnere på "Nova Hedwigia" for
at erhverve tillæggene.

Helmut Garns: Flechten (Lichenes) . Kleine Kryptogamenflora III, udgivet af HELMUT GAMS. - 244 s., 84 fig. Gustav Fisehers Verlag. Stuttgart
1967. - Pris DM 28.-.
I den nyttige serie af mellemeuropæiske kryptogamfloraer i lommeformat er der nu også kommet et bind om laver, udarbejdet af seriens
redaktør. En sådan bog har længe været imødeset med forventning, for vi
mangler i høj grad sammenfattende lavfloraer.
De færreste lichenologer har haft mod til at gå i gang hermed måske afskrækkes de af, at der stadig mangler special-monografier over
mange store og artsrige slægter af laver, samt af det forhold, at laverne
er dobbelt-organismer, hvad der yderligere gør det vanskeligt at opstille
en fornuftig lav-systematik.
Det er derfor meget fortjentsfuldt, at HELMUT GAMS, som ikke selv er
lavforsker af faget, har påtaget sig at skrive en lavflora for Europa,
og det skal siges med det samme, at det er lykkedes ham at løse opgaven
fortrinligt, når der tages hensyn til den begrænsede plads, der har stået til
hans rådighed.
Det siger sig selv, at det har været umuligt at få alle de fra Mellemeuropa angivne arter af laver med, især af skorpelaverne; men det er der
nu heller ikke sket nogen større skade ved, for en stor del af disse arter
er ret tvivlsomme og skal maske snarere betegnes som modifikationer end
som arter. Ligeledes har forf. i almindelighed ikke medtaget arter, som
kun adskiller sig fra andre lignende arter ved sporernes dimensioner eller
ved kemiske reaktioner, og der er heller ikke medtaget arter, som kun er
angivet fra en enkelt lokalitet. Til brug for dem, som ønsker at gå mere i
dybden med deres lavstudier, er der givet oplysning om den forhåndenværende (men desværre ikke altid tilstrækkeligt fyldestgørende) speciallitteratur.
Oplysningerne om arternes udbredelse er ret detaillerede med rimelig
hensyntagen til de nordiske lande. Det kan således nævnes, at det er om
den i Nordamerika hyppige, men i Europa sjældne art Caloplaca microphyllina (TUCK.) HASSE angives, at den forekommer i 0stalperne, i Danmark og i Sydsver~ge. Ligeledes noteres, at det om den i Troperne og i
Subtroperne vidt udbredte art Graphis elegans (SM.) ACH. angives, at den
forekommer i Vesteuropa indtil Skotland, i Danmark og i Tyskland til
Weser og Schwarzwald.
Det kan yderligere nævnes, at der også er blevet plads til en omtale af
de hovedsageligt subarktiske og alpine basidiolichener. Af særlig interesse
for danske forhold er de dobbelt-organismer, som dannes ved symbiose
mellem grønalger af slægten Coccomyxa og bladhatte af slægten Omphalina) dels Botrydina vulgaris med homoeomert, grynet thallus og dels Coriscium vulgare med heteromert thallus af form som små runde skæl.
De anførte eksempler turde være tilstrækkelige til at dokumentere, at
bogen er særdeles brugbar, også for et dansk publikum. Den være hermed
anbefalet på det bedste.

FORENINGEN TIL SVAMPEKUNDSKABENS FREMME.
ORDINÆR GENERALFORSAMLING I 1963.
Torsdag d. 21. februar 1963, kl. 20,00, afholdtes den ordinære generalforsamling i Botanisk Laboratoriums auditorium, Gothersgade 140.
Fabrikant Sv. TROYER valgtes til dirigent og erklærede generalforsamlingen for lovligt indvarslet.
a. Formanden, professor N. F ABRITIUS BucHwALD, aflagde derpå
beretning for året 1962. Sommerens triste vejr, der var koldt og fugtigt, er der gjort nærmere rede for i indledningen til ekskursionsberetningerne for 1962 ("Friesia " 7: 134-135, 1963).
N år artsantallet på svampeudstillingen trods de dårlige vejrforhold kom op på 256, skyldes det en stor ihærdighed hos de mange,
der deltog i indsamlingen. Om udstillingen, se "Friesia" 7: 147-149,
1963.
Blandt ekskursionerne var der særlig grund til at nævne den vellykkede weekend-tur den 8.-9. september til Andrarum i Skåne, hvor
der blev fundet bemærkelsesværdigt mange eksemplarer af Pisolithus
tinetorius (ærtetrøffel ). *)
Efter ekskursionsberetningen vistes farvelysbilleder fra årets
ekskursioner optaget af redaktør BØRGE RØNNE.
Angående "Friesia" nævnte formanden, at heftet, der skulle gælde
for 1962, var på trapperne. En glædelig ting var det, at overlærer
K. BJØRNEKÆR havde modtaget 13.000,00 kr. af Carlsberg-Fondet til
trykning af sin store monografi over de danske slimsvampe.*":- ) Fra
undervisningsministeriet var modtaget 1.750,00 kr. for finansåret
1961/62.

Medlemstallet viste en tilbagegang på 4 medlemmer. I beretningsåret var 5 medlemmer afgået ved døden, nemlig: Sproglærer VALDEMAR CHRISTENSEN, overretssagfører W. KARNOV, fhv. retspræsident
K. MUNDT, overlærer F. H. MØLLER og fil. dr. E. G. RENNERFELT.
Formanden udtalte særlige mindeord over retspræsident K. MUNDT,
fil. dr. E. G. RENNERFELDT og overlærer F. H. MØLLER. Over K. MUNDT
og E. G. RENNERFELDT er der optaget nekrologer i "Friesia", henholdsvis i bd. 7: 105-106 (1963) og 7: 372-374 (1964). Om sidstnævnte
udtalte formanden: "Ved overlærer F. H. MØLLER'S død har dansk,
ja nordisk mykologi lidt et meget stort tab. Der vil utvivlsomt gå
mange år, inden Danmark atter fostrer en så dygtig amatørmykolog.
MØLLER begyndte allerede få år efter sin indtræden i foreningen i
1912 - han havde altså ved sin død netop været medlem i 50 år at publicere om svampe. Et par af hans første betydelige bidrag til
dansk mykologi var fundene af den overordentlig giftige Teglstensrød Trævlehat (Inocybe patouillardii) syn. I. lateraria) og den ligeledes meget giftige Satans-Rørhat (Boletus satanas) ) begge arter
påvist første gang i Danmark af MØLLER. Siden har han, som vi alle
ved, skrevet meget. Jeg skal nøjes med blot at nævne hans to hovedværker: "Fungi of the Færoes", I-II (1945,1958) og den store Champignon-monografi: "Danish Psalliota species" (1950-52). Det sidstnævnte arbejde må vel betegnes som hans betydeligste og har vundet
almindelig anerkendelse overalt i den mykologiske verden. Den fremragende svenske agaricaceforsker, fil. dr. SETH LUNDELL skrev, da
han hørte om overlærer MØLLER'S død, bl. a.: "Han var den store
svampentusiasten ...... Fremforallt genom sin overdådiga Psalliotamonografi kommer hans namn alltid att leva, - et sannskyldigt
monumentum aere perennius!(( Personligt vil jeg mindes MØLLER som
min bedste mykologiske ven gennem 40 år. I næsten 20 år var han
min medredaktør af "Friesia". En mere nidkær, samvittighedsfuld og
pligtopfyldende medredaktør kan ingen ønske sig". - En nekrolog
over overlærer MØLLER vil senere fremkomme i "Friesia".
Vi vil ære disses minde.
b. Kassereren fremlagde derefter regnskabet, som blev godkendt.
c. De fire bestyrelsesmedlemmer, Fru ELISABETH ANDERSEN, professor N. F. BUCHWALD, amanuensis J. KOCH og redaktør BØRGE
RØNNE og suppleanten, afdelingsbestyrer PAUL NEERGAARD, der afgik
efter tur, blev alle genvalgt.
d. Som revisor genvalgtes ekspeditionssekretær K. RANKOV.
-

e. Formanden forelagde et forslag om at udnævne fil. dr. h. c.
SETH LUNDELL til æresmedlem af foreningen. Særligt fremhævede
formanden SETH LUNDELL'S udforskning af den svenske hymenomycetflora og hans medvirken ved udgivelsen af exsikkatværket "Fungi
exsiccati suecici". Forslaget blev vedtaget med akklamation (se
"Friesia" 7:107, 1963).
f. Følgende ekskursioner blev foreslået: Boserup Skov og Skovvænge samt Hvalsø-skovene, Romele Klint, Tisvilde Hegn, Aastrup
Skov og Kongsøre Skov.
g. Eventuelt. Intet at bemærke. Generalforsamlingen hævet. Formanden takkede dirigenten.
sign. Sv. TROYER
Efter generalforsamlingen holdt forsøgsleder, havebrugskandidat
C. RIBER RASMUSSEN et interessant foredrag med titlen: "Nyere
fremskridt inden for champignondyrkningen".
Efter mødet samledes man til tvangfrit samvær på Universitetets
Spisestuer, Nørregade 10.

EKSKURSIONER I 1963.
Søndag den 19. maj 1963. Ekskursion til B o s e r u p S k o v og
S k o v h u s V æ n g e. Ca. 45 deltagere, hvoraf 31 med bus. Efter
en usædvanlig lang vinter med is og sne blev det endelig forår. Bøgeskoven havde kun været fuldt udsprunget et par dage, da ekskursionen fandt sted. Bøgebladene var endnu smukt lysegrønne, violerne
netop kommet i blomst, slåenbuskene var lige ved at springe ud, og
skovbundsfloraen, som er så rig både i Boserup og Skovhus Vænge,
stod på sit højeste. Det måtte være Morkeltid ! Men nej! De var endnu
ikke rigtigt kommet frem, så der fandtes kun få eksemplarer (Morchella esculenta) i Boserup og slet ingen i Skovhus Vænge. Jordtemperaturen var åbenbart endnu for lav.
Skønt det øsregnede klo 6-7, var skovbunden allerede blevet tør
ved ankomsten til Boserup Skov, og det blev tørvejr resten af dagen.
På Hotel Postgaarden, Køge, hvor frokosten skulle være indtaget,
var der ikke plads, og vi kørte derfor videre til Vallø Strandhotel, syd
for Køge, efter at vi ved en opringning havde forvisset os om, at

hotellet havde plads til et halvt hundrede frokostgæster. Efter frokosten kørte vi kl. 13112 til Skovhus Vænge, og kl. 16 forlod vi parkeringspladsen ved Yderholm Kro og var i København ved 17-tiden.
Storsvampefloraen, især Bladhatfloraen, var yderst ringe på begge
lokaliteter, øjensynligt af samme årsag som angivet for Morklernes
vedkommende. Opmærksomheden koncentreredes derfor for en del
til de parasitiske Mikromyceter. Der er grund til at nævne, at ny for
den danske flora er vist H eterosporium vegetum) der fandtes i Skovhus Vænge på en nedfalden Bøgepind sammen med Hypoxylon fragiforme) samt at Fusidium eburneum fandtes på en for landet ny vært,
Ficaria verna. laIt iagttoges 56 arter. Bestemmelsen af de resupinate
arter skyldes tandlægerne K. HAUERSLEV og J. E. BREGNHØJ LARSEN.

Søndag den 25. august 1963. Ekskursion til L i Il e D y r e h a v e,
I n d e l u k k e t og J æ g e r b a k k e n. Deltagerantal 27 med tog til
Slotspavillonens st., hvortil ankomst kl. 9,16; en halv snes deltagere
kom i egen befordring. - August måned var usædvanlig regnfuld,
med en samlet nedbør på 154 mm (normalt 83 mm) og således endnu
fugtigere end nogen måned i de ellers regnrige somre 1960-62 (jfr.
Friesia 7: 134-135).*) Da temperaturen tilmed for hele måneden lå
lidt over normalen, var der således skabt betingelser for en god
svampesæson. Svampeudbyttet på denne og de følgende efterårsekskursioner skuffede da heller ikke, tværtimod. Der fandtes på
denne ekskursion 159 arter, hvoraf alene 99 Agaricalesj som sædvanligt på denne årstid dominerede rør- og skørhattene, med henholdsvis 10 og 19 arter.
Fra Slotspavillonens st. gik man gennem anlægget omkring
S l o t s p a v i Il o n e n, der viste sig at være en god lokalitet for Boleter(Boletus miniatoporus og B. edulis) og Kantareller; her fandtes
også 4 smukke eksemplarer af Tue-Poresvamp (Polyporus jrondosus)
ved foden af gamle Ege. Derefter gik turen ind i L i Il e D y r eh a v e, hvor bl. a. et enkelt mindre Egetræ tiltrak sig opmærksomheden ved dets mange hvide blade, som lyste langt bort. Bladene viste
sig at være tæt dækket med peritecier af Egemeldug ; endvidere note*) Man skal helt tilbage til 1891 for at træffe en tilsvarende stor nedbør
i august.

redes her de sjældnere rørhatte: Boletus castaneus og B. pulverulentus samt Russula sororia under Eg. Ved 12-tiden indtoges frokosten i
restaurant "Rosenhaven" ved Frederiksborg Slotssø. I kronen af et
stort Gråpæretræ (Pyrus communis) i restaurationshaven sad taglagt
stillede frugtlegemer af Polyporus sulphureus. Efter en demonstration af formiddagens svampefund sejlede vi over Slotssøen til I n d el u k k e t, hvor vi straks overraskedes af en regnbyge, der dog kun
blev kortvarig. I Indelukket fandtes ikke nær så mange svampe som i
Dyrehaven. På et gammelt Bøgestød voksede en rig flora: Crepidotus
moZlis) Polyporus giganteus) P. varius og Stereum rugosum. Peritecier af Egemeldug fandtes også her på en gammel Eg's lavt siddende
blade*). Fra Indelukket gik vi ind i Frederiksborg Slotsh a v e, hvor det interessantes te fund var den sjældne Thelephora
spiculosa) der voksede op ad græsstængler, og ekskursionen sluttede
på "J æ g e r b a k k e n", hvor der fandtes talrige i græs voksende
eksemplarer af Hummer-Skørhat (Russula xerampelina) i mange
udviklingsstadier .
Udbyttet af spisesvampe var ret stort. Der indsamledes mange
Kantareller, "Karl Johan", Punktstokket Rørhat og enkelte eksemplarer af Mandel-Champignon og Pigsvamp.
Ved udarbejdelsen af den følgende artsliste er foruden egne notater
benyttet lister modtaget fra fru ELISABETH ANDERSEN, overlærer M.
P. CHRISTIANSEN, tandlæge K. HAUERSLEV og tandlæge J. E. BREGNHØJ LARSEN.

*) Fundet af peritecier hos Egemeldug (Microsphaera alphitoides) i stor
mængde må betegnes som ekskursionens mest interessante oplevelse.
Det skulle senere vise sig, at Egemelduggen også havde udviklet peritecier på andre lokaliteter i landet; bl. a. fandtes talrige peritecier på
egetræer i Landbohøjskolens have, Rolighedsvej. Der er tidligere mange
gange søgt efter peritecier, men indtil 1963 var de kun iagttaget 2-3
gange i Danmark (jfr. FERDINANDSEN & JØRGENSEN: Skovtræernes Sygdomme, 1938-39).

Søndag den 8. september 1963. Ekskursion til G a n l ø s e E g e d,
K r o g e n l u n d og U g g e l ø s e S k o v. Ca. 55 deltagere mødte
op ved togets ankomst til Farum st. kl. 9,49, hvorfra de i taxa og
private vogne transporteredes videre til vestkanten af Bastrup Sø;
her tog ekskursionen sin begyndelse med en gennemsøgning af Ganløse Eged. Af mere bemærkelsesværdige fund kan nævnes Boletus
appendiculatus og B. porphyrosporus) som begge fandtes flere steder,
Clitocybe injundibulijormis med et frugtlegeme i superposition i
normal stilling, Lactarius volemus) flere eksemplarer, og en snes individer af Amanita phalloides) hvoraf et enkelt med en stærk afvigende
farve, nærmest glinsende grå og kun med en ganske svag grønlig
tone i hatranden, men med tydeligt vatret stok.
Frokosten indtoges på traktørstedet ved Bure Sø, som desværre
viste sig at være alt for lille til det store rykind; adskillige måtte
betjene sig selv, og mange nåede endda ikke at få en kop kaffe. Om
nogen svampedemonstration kunne der under disse forhold ikke blive
tale.
Efter frokosten gik turen op gennem den vestlige del af Krogenlund, som væsentligt består af gammel Bøgeskov. Her var det interessanteste fund Hydnotrya tulasnei. Sammen med redaktør B. RØNHE,

der fandt det første eksemplar, lykkedes det os på morbund under en
gammel Bøg at finde 15-20 eksemplarer. De ti største frugtlegemer,
der tilsammen havde en friskvægt på 86 g -X- ), havde følgende mål:
4.75X3.75X2.25 cm
4.25 X 4.25 X 2.50 4.25 X 3.00 X 2.00 4.00 X 3.50 X 1.50 4.00 X 3.25 X 1.75 -

3.50 X 2.50 X 1.50 3.25 X 2.75 X 1.75 3.00 X 2.25 X 1.00 2.00 X 1.50 X 1.00 -
Et andet interessant fund var Hypholoma cotoneum) ved hvis gule
stokbasis der fandtes sklerotier:>:--X- ) På den kendte store hængebøg i
den nordlige udkant af Krogenlund voksede Armillaria mucida. Ekskursionen afsluttedes med et på grund af den stærkt fremrykkede
tid kortvarigt besøg i Uggeløse Skov. Her voksede Schizophyllum
commune og Polyporus hirsutus i stor mængde på tørre, barksprukne,
gamle Bøgekævler, der havde ligget for længe i skoven.
Der noteredes lige som på den forrige ekskursion et ret betydeligt
artsantal, nemlig 139, hvoraf 90 var Agaricales; der noteredes ingen
resupinate arter. Udbyttet af spisesvampe var godt og bestod især
af Kantarel, Trompetsvamp, Pigsvamp, Punktstokket Rørhat, PerleFluesvamp og Rabarber-Parasolhat.

Søndag den 22. september 1963. Ekskursion til G r e v i n g e S k o v
og K o n g s ø r e S k o v. Ekskursionen udgik fra Studenterforeningen, H. C. Andersens Boulevard, hvor 27 deltagere samledes kl. 8.
Under køreturen fortalte redaktør B. RØNNE i korte træk om inddæmningen af Lammefjord og Sidingefjord. Samtidig gjorde han
opmærksom på, at da Gundestrup Kro kun kunne huse 30 personer
med "medbragte madkurve", var frokosten blevet forlagt til Vig Kro,
hvor vi senere blev vel modtaget, og hvor arrangementet klappede
fuldkomment. Ingenør HERTZ gennemgik her efter frokosten i korte
træk formiddagens fund.
Efter ankomsten til Grevinge Skov ved 9,15-tiden spredtes man i
terrænet. Af særlige fund i denne skov kan nævnes: Xylaria longipes
på bøg; M erulius serpens også på bøg; Trametes mollis på asp;
Hypholoma cotoneum med sklerotier*); Lactarius acer (eet eksemplar) ; Hebeloma (Pholiota) radicosum i adskillige eksemplarer.
Fra eftermiddagens tur i Kongsøre Skover der anledning til at
notere følgende fund: Microsphaera alphitoides med peritecier på
talrige blade af stødskud ; **) Gomphidius viscidus)· Russula sororia
under eg; Geaster jimbriatus)· N aucoria myosotis f. macrospora.

Søndag den 6. oktober 1963. Ekskursion til V r a n g e s k o v og
S k j o l d n æ s h o l m. 56 deltagere. I gråvejr startede man med bus
lidt over kl. 8 fra Studenderforeningen og nåede frem til Vrangeskov
Kro til planlagt tid, ca. kl. 9,30. Efter at professor N. F. BUCHWALD
havde givet en lille oversigt over de historiske begivenheder omkring
mordet på Knud Lavard i 1131, gennemsøgte man "skoven med de
vrange bøge". Noget rigt svampeflor var her ikke; der er dog noteret
140 arter herfra. På et bøgetræ bag kroen fandtes mange frugtlegemer af Polyporus pjeifferi) og på et dødt, kroget bøgetræ foran kroen
fandtes følgende 7 arter: Coprinus micaceus) Dictydiaetalium plumbeum) Hypoxylon coccineum) Libertella jaginea) Polyporus jomentarius) Psathyrella disseminata og Ustulina maxima. Efter frokosten og
fru ELISABETH ANDERSEN'S demonstration af de indsamlede svampe
fortsattes turen til Skjoldnæsholm. På vejen dertil gjorde man et
øjeblik holdt for at betragte mindekorset for KNUD LAVARD. I skoven
ved Skjoldnæsholm fandtes straks en interessant lokalitet i en beplantning med Cypres, hvor der før havde stået Rødgran; det bløde
mostæppe var rigt på svampe, især Cortinarius cinnamomeus, Lepiota
amianthina) Lepiota carcharias og Limacium pustulatum. Efter et
besøg på Gyldenløveshøj, hvor det blæste koldt, tiltrådtes hjemturen;
dog måtte man først beundre to flotte eksemplarer af Pholiota aurea)
som fru ASTA PETERSEN havde fundet ved vejen. Dagen var forløbet
godt, til dels i solskin og med kun en enkelt regnbyge ved frokosttid.
Ved hjælp af lister fra professor N. F. BUCHWALD, kaptajn M. P.
CHRISTIANSEN og ingeniør S. HERTZ kommer den fuldstændige liste
på 202 arter og varieteter til a t se således ud:

Søndag den 20. oktober 1963. Ekskursion til J æ g e r s b o r g D Y r eh a v e. Ca. 50 mødtes ved Klampenborg St. Vejret var mildt efter
årstiden, og solen skinnede. Om formiddagen afsøgtes den sydøstlige
del af Dyrehaven, og af fund kan nævnes Hydnum coralloides på en
i hvert fald for Danmark ny vært, Ulmus glabra.*) Desuden kan nævnes
Tremella joliacea på Eg og Phaeolepiota (Pholiota) vahlii. Frokosten
spiste s på "Kildeøen", for manges vedkommende i det fri, lokket af
solen. Om eftermiddagen gik man ad Indelukket til, men da der
ekskursioneredes under vejs, nåede kun et fåtal frem. Indelukket bør
stryges, da det ikke er første gang, man ikke er nået frem, og man
må om eftermiddagen i stedet for koncentrere sig om den sydlige del
af Dyrehaven, i hvert fald hvis udgangspunktet er "Kildeøen".
Efterfølgende 133 arter noteredes.

SVAMPEKURSUS 1963.
For medlemmer (begyndere) afholdt foreningen på Den kgl. Veterinær- og Landbohøjskole et svampekursus mandagene den 23. og
30. september og den 7. og 14. oktober 1963, hver gang kl. 19,30-21,00.
Kurset omfattede dels en gennemgang af storsvampenes systematik
og biologi, dels en vejledning i bestemmelse af storsvampe. I kurset,
der lededes af foreningens formand og sekretær, deltog 22 medlemmer. Prisen pr. deltager var 25 kr.

ORDINÆR GENERALFORSAMLING I 1964.
Fredag den 28. februar 1964, klo 20,00, afholdtes den ordinære
generalforsamling i Botanisk Laboratoriums auditorium, Gothersgade
140.
Fabrikant Sv. TROYER valgtes til dirigent og konstaterede, at geneneralforsamlingen var lovligt indvarslet.
a. Formanden, professor N. FABRITIUS BUCHWALD, aflagde derefter beretning for året 1963. I tilknytning til omtalen af de enkelte
ekskursioner fremvistes farvelysbilleder, et festligt og godt indslag.
Foruden ekskursionsbillederne vistes der farvelysbilleder af den
sjældne Rørhat, Boletus satanas. Billederne var taget af politiadvokat
BIRGER WILCKE, som havde fundet Satans-Rørhatten i det sydlige Fyn.
I 1963 var der ingen svampeudstilling, men der afholdtes et
svampekursus. Nærmere herom side 95.
I slutningen af 1963 udsendtes et stort hæfte af "Friesia" på
næsten 160 sider, det første hæfte af det nye bind 7. Hovedafhandlingen er en detaljeret redegørelse af fil. dr. LENNART HOLM & professor J. A. NANNFELDT for det berømteste af alle svampeexsiccater,
nemlig det af E . FRIES udgivne exsiccat "Scleromyceti Sueciae", der
udsendtes i 10 fascikler indeholdende 340 svampearter, ganske overvejende Pyrenomycetes) udgivet 1819-1822 (1825). Hæftet indeholder
desuden et billede af foreningens første udenlandske æresmedlem
dr. h. c. SETH LUNDELL og en medlemsfortegnelse. Næste hæfte var
på trapperne og vil indeholde overlærer K. BJ0RNEKÆR'S og grosserer A. B. KLINGE'S store monografi over danske Slimsvampe.
Fra undervisningsministeriet modtoges for 1962/63 kr. 1.750.-;
for nærværende finansår er der, som sidste år, søgt om kr. 2.000.-.
Medlemstallet var desværre gået tilbage fra 482 pr. 1.1.1963 til
463 pr. 1.1.1964. Antallet af udenlandske medlemmer er glædeligvis
i stadig stigen og udgør 140 pr. 1.1.1964.
Også i dette beretningsår har foreningen lidt store tab ved dødsfald: Professor E. GAUMANN, grosserer A. B. KLINGE, frk. R. MUNKVAD og direktør M. P. WILKENS, alle medlemmer, der havde stået i
foreningen i mange år:r.)
På en af de sidste dage døde den betydelige schweiziske mykolog
og plantepatolog E. GAUMANN (1893-1963), kort efter at være fyldt

70 år. Han var vel på sine ældre dage foreningens mest berømte medlem; han havde været abonnent på "Friesia" siden dets start i 1932*).
Deres minde blev æret.
b. Kassereren fremlagde herefter det reviderede regnskab, der
blev godkendt uden bemærkninger. Af regnskabets poster kan nævnes, at udgiften til trykning af det netop udkomne nummer af
"Friesia" beløb sig til kr. 13.606.
c. Bestyrelsesmedlemmerne overlærer K. BJØRNEKÆR, tandlæge K.
HAUERSLEV og ingeniør S. HERTz afgik efter tur og blev genvalgt.
Suppleanten, mag. scient. fru E. LøHR ønskede ikke genvalg, og formanden foreslog som ny 1. suppleant dr. JOHANNES JØRGENSEN, som
valgtes.
d. Som revisor genvalgtes K. RANKov.
e. Som emner til ekskursioner blev foreslået Kongelunden, Mogenstrup As, Bornholm (week-endtur). En sommertur til Tisvilde Hegn
med tog eller til Rådvad. Endvidere week-endtur til Midtjylland eller
Corseli tze-skovene.
f. Under eventuelt oplæste formanden et brev fra ingeniør E.
TRYLL, hvori denne foreslog en ændring af forenings navnet. Formanden redegjorde for forenings navnets tilblivelseshistorie og konkluderede, at han og andre i bestyrelsen fandt det uheldigt at skifte
navn, idet det kun ville skabe uklarhed, men erklærede, at generalforsamlingen hverken kunne forkaste eller godkende forslaget, da
dette ikke var fremsendt til bestyrelsen inden afvigte nytår, som det
skulle have været efter foreningens love.
Generalforsamlingen hævedes, og dirigenten takkedes.
(sign.) Sv. TROYER.
Professor N. F. BUCHWALD holdt efter generalforsamlingen følgende foredrag: "I hundredåret for tre danske mykologers fødsel".
De tre mykologer er: JAKOB E. LANGE (1864-1941), POUL LARSEN
(1864-1938) og OVE RoSTRUP (1864-1933). Foredraget ledsagedes af
lysbilleder. - Efter mødet var der tvangfrit samvær på Universitetets Spisestuer.

EKSKURSIONER I 1964.
Søndag den 24. maj 1964. Ekskursion til B o s e r u p S k o v og
H e r t h a d a l e n. Ca. 30 deltagere, hvoraf 30. med bus. Landet var
usædvanligt grønt og frodigt og præsenterede sig særligt godt i det
smukke solskinsvejr. Boserup Skov gav mange eksemplarer af Spiselig Morkel (Morchella esculenta) og en enkelt Hætte-Morkel (M. rimosipes). Om eftermiddagen gik hovedparten af deltagerne gennem
Herthadalen til Ledreborg Slotspark; de øvrige af selskabet kørte.
Eftermiddagsturen volder vanskeligheder for bilisterne, der må tilbage for at hente deres vogne. Det var nok rimeligt af denne grund
at lægge turen noget om.
Kun ganske få Agaricaceer noteredes. De resupinate arter er samlet og bestemt af tandlægerne K. HAUERSLEV og J. E. BREGNH0J LARSEN, og de parasitiske micromyceter af licentiatstuderende L. A. HoBOLTH. Der fandtes ialt 64 arter.

Søndag den 23. august 1964. Ekskursion til R u d e S k o v. Der
var 25 deltagere med toget til Birkerød st., hvortil vi ankom kl. 9,54;
en halv snes deltagere kørte i egen befordring. Sommeren 1964 havde
været kølig og juni og juli haft ret mange regnsvejrsdage, men august
var mod sædvane meget fattig på nedbør (sml. årene 1962 og 1963,
"Friesia" 7: 134-135 og 8:83). Ugen forud for ekskursionen var ganske tør, og solen strålede på hele ekskursionsdagen.
Om formiddagen gik turen forbi Ebberødgaard og Skovrøddam.
Frokosten spistes på "Lollikhus", og efterfulgtes af en demonstration af de indsamlede svampe. Om eftermiddagen fortsatte man gennem den østlige del af Rudeskov og gennem Holte Villaby til stationen, hvorfra de fleste deltagere tog hjem med toget 16,48.
Af de fundne svampearter må bl. a. fremhæves følgende: Boletus
pachypus) Helicomyces roseus) der dannede smukke, lillafarvede overtræk på Bøgestød, Helotium monilijerum på Bøgestød, som var angrebet af Bispora monilioides) Hypocrea citrina på og omkring stærkt
frønnet Egestød, Schizophyllum commune på grene af Larix) Rutstroemia petiolorum på fugtigt liggende, visne Egeblade samt Puccinia

synes at være rapporteret fra Danmark.
Skønt der blev noteret ikke færre end 162 arter, deriblandt 87
Agaricales) må svampefloret ikke desto mindre betegnes som meget
pauvert. Der samledes næsten ingen spisesvampe, væsentligt Boletus
edulis og B. appendiculatus. De res up ina te svampearter er bestemt af

Søndag den 6. september 1964. Ekskursion til G a v n ø. Der var
28 deltagere med bussen, og et dusin kom i egen befordring. Det
tørre vejr, som kendetegnede august, fortsatte ind i september måned,
og følgen blev, at svampefloret også fortsatte med at være fattigt.
Der noteredes ganske vist 120 arter på denne ekskursion, men heraf

Ekskursionen indledtes med et besøg i den store Gavnø Slotspark,
som viste sig at være en forholdsvis rig svampelokalitet. Her vokser
mange sjældne træarter, og på flere af de gamle træer fandtes Pore-

Formiddagen afsluttedes med et besøg kl. 11-12 i slotskapellet,
hvor vi først påhørte en højttalerudsendelse (indtalt ved baron
REEDTZ-THOTT) om Gavnø Slots historie og derefter under kyndig
vejledning vistes rundt i slottets storslåede malerisamling, den største privatsamling i Skandinavien.-x-)

I 1960 overlod den nuværende ejer, baron AXEL REEDTZ-THOTT Gavnø
Slot, parken og den væsentlige del af det historiske indbo (herunder
malerisamlingen) til en selvstændig institution: Gavnø Fonden.

Frokosten indtoges kl. 12,15-13,30 i "Karetmagerens Hus", en
smuk gammel bindingsværksbygning, nu indrettet til restaurant. Efter
en svampedemonstration kørte vi til Lønned Skov på sydspidsen af
øen Gavnø. Den mest interessante lokalitet her var græssletten omkring baron REEDTZ-THOTT'S sommerhus, "Sofienlyst", hvor der vokser
mange gamle, fritstående ege. På et enkelt træ taltes ikke færre end
34 frugtlegemer af Polyporus (Fomes) robustus (se fig. log 2);
i øvrigt noteredes på Egene: Daedalea quercina) Polyporus dryadeus
ved grunden af en stamme, P. fumosus på et stød og P. sulphureus i
kronen af et træ. I Lønned Skov fandtes bl. a. den af M. P. CHRISTIANSEN beskrevne Phlebia (Peniophora) danica på gren af Fraxinus.
Godt 16,00 forlod vi Gavnø og var hjemme i København ved 18tiden efter en vel tilbragt dag trods det noget pauvre svampeudbytte.
Foreningen havde gennem Gavnø Godskontor indhentet særlig
tilladelse til fri entre til slotsparken og slottet samt til ekskursion i
Lønned Skov.

Søndag den 13. september 1964. Ekskursion til H a r e s k o v. Selv
om svampeudstillingen blev aflyst,+<) løb denne lille halvdagsindsamlingsekskursion alligevel af stabelen. Der mødte 9 deltagere, og
der blev i løbet af formiddagen fundet 44 arter. Der var mange
svampe i Hareskoven, hvilket var forbavsende i betragtning af, hvor
få storsvampe der fandes på ekskursionen til Gavnø. Af fund var det
mest nævneværdige nok nogle smukke eksemplarer af Cortinarius
bolaris.

Søndag den 4. oktober 1964. Ekskursion til Køge Strandskov,
p r a m s k o v og P u r l u n d. Der var 29 deltagere med bus og en
halv snes i egen befordring. September måneds tørre vejr fortsattes
ind i oktober og satte sit præg på ekskursionens svampe udbytte, men
i øvrigt blev søndagen den 4. oktober en dejlig efterårsdag med strålende sol og vindstille.
Om formiddagen ekskursioneredes i Køge Strandskov, hvis vestlige del - vest for volden - i de senere år er blevet forvandlet fra
Fyrreskov til Bøgeskov. Som sædvanligt bød skoven på interessante
ting som Flammula penetrans i stor mængde på Fyrregrene, Lepiota
clypeolaria og L. seminuda omkring bevoksninger af Brændenælder,
Mycena janthina sensu RICKEN med smuk lilla stok, hat og lamelrande, Omphalia pyxidata) Pluteus salicinus på Quercus og Polyporus
annosus på Pinus silvestris) flere steder. Efter frokost på Vallø
Strandhotel afholdtes svampedemonstration, og derpå gik turen
videre til Pramskov og Purlund. Udbyttet i disse to småskove, der
overvejende består af Bøg, var meget ringe; et af de interessantes te
fund var Polyporus (Fomes) pfeifferi ved grunden af en gammel Bøg.
Der noteredes ikke færre end 184 arter, et ret betydeligt antal i
betragtning af den tørre, svampefattige sæson, men individrigdommen

Søndag den 18. oktober 1964. Ekskursion til J æ g e r s b o r g D Y r eh a v e. Ca. 50 deltagere var mødt i det gode vejr. Turen gik ned til
skovridergården og derfra til restaurationen "Kildeøen". Straks ved
turens begyndelse lykkedes det redaktør B. RØNNE at genfinde den
sjældne pigsvamp Hydnum ramosum (coraZloides) på en kævle af en
UZmus sp. (se beretningen for Dyrehaveturen d. 20. oktob. 1963). Af
formiddagens fund kan endvidere nævnes et usædvanligt stort og smukt
eksemplar af TrichoZoma personatum. Eftermiddagsturen gik ned
langs Fuglesangssøen, hvor det var blevet meddelt foreningen, at
der stod en gruppe af PhaeoZepiota vahZii. Gruppen blev genfundet
ved nordsiden af søen på en for denne svamp typisk lokalitet: dyb,
fed muld i kraftig omsætning, bevokset med en rig nældevegetation.
Der taltes 140 store, veludviklede eksemplarer på et område af størrelsen % X 1% m. På hjemvejen gik vi en lille omvej for at syne en
belægning af slimsvampen BrejeZdia maxima i VON LANGEN'S Plantage. Svampen dækkede næsten fladen af et 8tort bøgestød og var
desuden "klatret" op i nogle nærstående nælder, omkring hvis stængler den havde dannet belægninger, der af størrelse og farve mindede
om den valseformede frugtstand hos Dunhammer.
