I must say t h a t t h e l a s t t h r e e y e a r s and t h e i r accompanying o f f i c e s have been considerably l e s s h e c t i c than t h e f i r s t three! But I have derived much p l e a s u r e and s a t i s f a c t i o n from s e r v i n g you and I am g r a t e f u l f o r t h e honor you accorded me when you e l e c t e d me P r e s i d e n t . Following a shaky s t a r t a t t h e beginning of t h e decade (we counted a n e t i n c r e a s e of only 39 new members i n all c a t e g o r i e s from December 1959 t o December 1 9 6 ~ t)h~e S o c i e t y has come back s t r o n g l y . During t h e period December 1961 t o December 1964 we r e g i s t e r e d a n e t i n c r e a s e o f s l i g h t l y over 300 new members. This phenomenal growth o f about 28% i n t h r e e y e a r s was t h e r e s u l t o f t h e e f f o r t s of many dedicated members o f t h e Society; but one person, D r . C . T. Rogerson, must be s i n g l e d out a s having done much more than h i s s h a r e i n b r i n g i n g about our r e v i v a l , i f not our s u r v i v a l . Following a p e r i o d o f 13 months d u r i n g which only one i s s u e of bfycologia was published, D r . Rogerson guided 21 i s s u e s of t h e j o u r n a l through t h e p r e s s i n 24 months, and Mycologia once again w a s appearing regul a r l y by e a r l y 1963.

Six half-day sessions have been arranged, of which two are joint sessions of the Mycological Society and the Microbiological Section of the Botanical Society of America. Current scheduling arrangements indicate that the formal program of the Society will end with theiaf"cernoonsession of Wednesday, August 18. Dr. D. P. Rogers, Department of Botany, University of Illinois, is the local representative on program arrangements for the Mycological Society. IV.

Held, Department of Botany, University of California, Berkeley, to be the recipient of the Societyrs graduate fellowship for 1965-1966. The stipend awarded was $750. V. ELECTION OF OFFICERS Ballots for election of new officers are being prepared for distribution in June. Ballots may be returned to the office of the Secretary-Treasurer up to a few days before the beginning of the Annual Foray in August. VI.

The revis3~n:haSbeen supervised by a committee of members Dr. Everett S . Beneke, Chm., ~ e o n R ' ; fieebone, : John B. Routien, and Alex L. Shigo. : VIII. GUIDEBOOK IN MYCOLOGY The committee on preparation of the Society1s "Guidebook.-inMycologyf1met in Washington, D. C., May 1-2 under the chairmanship of Dr. R. B. Stevens. . Manuscripts which have been received or which are expected will receive preliminary editing during the summer. Laboratory testing of the material is expected to occupy the time of two or three graduate students during the school year 1965-1966. IX. MEMBERSHIP As of June 1, 1965, membership of the Society, including applications on hand to be presented for election at the annual business meeting, was constituted as follows: ............................................... 7 Regular Members ........................................... 951 Sustaining Members ........................................ 34 Affiliated Societies ...................................... 7 Corresponding Members ..................................... 1 Emeritus Members .......................................... 19 Associates ................................................ 57 Life Members 1076 With 1076 members in all categories, the Society has a net gain of 54 members over last year at the same time. Delinquency in 1965 dues has necessitated dropping 61 individuals from active membership; reinstatement of many of these is predicted as soon as they discover that they no longer receive MYCOLOGIA. Fourteen former members resigned this year. Notice of the death of one member has been received since the issue of the December 1964 Newsletter. Deceased Member Dr. Manuel ~ose'pereira Filho, Porto Alegre, Brazil, died in 1963. Dr. Pereira had been a Life Member in the Society since 1948. (!Chis notice was received through the agency of Prof. A. C Batista, who was unable to obtain more specific details,) [ -19631 . X.

Va. ) Relation of age of host fungi to development of mycoparasites. Research was conducted to determine the basis for resistance of aged cells of some host fungi to mycoparasitism.. The resistance of old (30 hrs, or more) hy-phae of Phycomyces blakesleeanus to penetration by Piptocephalis virginiana and other haustorial parKites was found to be primarily mechanical but modified by nutrition of the host. Hy-phal tips were penetrated readily, fl-equently resulting in curling and swelling. Old hy-phae of Choanephora cucurbitarum showed little mechanical resistance to the parasite. Aged cells of hosts of non-haustorial biotrophic mycoparasites (~alcarisporiumparasiticum and Gonatobotrys simplex) showed no greater resistance than did young cells. The necrotrophic mycoparasite Gliocladium roseum showed great,er ability to destroy young host cells and young perithecia than aged tissues of the host. FARR, Marie L. (~ationalFungus Collections, Plant Industry Station, Beltsville, Md. ) An old fungus re-identified. allogena Syd. was originally considered a hy-perparasite of Isaria acaricida Pat., a fungus described as growing on spiders on Chusquea leaves. The p r e s e n t ~ e m o n s t r a t e sthat D. allogena and I. acaricida are superficial stages of one fungus which possesses a well-developed hypostroma and belongs in Antennularia (~enturiaceae). The fungus is also shown to be identical with Dimerina negeriana (P.n. ) Theiss. and Asteridium chusqueae Rehm. Since the latter is the earliest name for the perfect stage, t'ne new combination Antennularia chusqueae (~ehm)is proposed as the correct name for the f'ungus under consideration. FTJLLER, Melvin S . (~niversityof California, Berkeley, Calif.) A P;l-thiumsp. parasitic on the marine alga Porphyra. In the summer of 1964, several species of Porphyra in the Friday Harbor, Washington, Area were examined for marine Phycomycetes. Among the fungi observed, one coenocytic form was parasitic and caused white lesions on the red fronds of Porphyra sp. The mycelium grows from*cell to cell, leaving the infected cells clear and devoid of contents. The f'ungus -was isolated on a marine medium and is a Fythium sp. Zoospores and hyphae of the f'ungus can be used to infect three species of Porphyra in the laboratory. Further studies on the biology of this parasitic phycomycete will be reported .

Upon conidiatio~,the amount of the sugar trehalose in the mycelium is significantly lower than is Yound in that of aconidial strains during corresponding periods of growth.

Liquid media containing sugars and asparagine or aLnmonium nitrate, with and without sodium formaldehyde desulfoxylate, in 25 m l cotton-stoppered conical flasks, were inoculated with liquid-grown, finely chopped, washed cells and were incubated in anaerobic jars. The jars were evacuated and filled with 100% nitrogen gas.
