Dear Fellow Members:

Nearly six years have passed since I began my three-year tour of duty as your Secretary-Treasurer. I must say that the last three years and their accompanying offices have been considerably less hectic than the first three! But I have derived much pleasure and satisfaction from serving you and I am grateful for the honor you accorded me when you elected me President.

Following a shaky start at the beginning of the decade (we counted a net increase of only 39 new members in all categories from December 1959 to December 196~)~the Society has come back strongly. During the period December 1961 to December 1964 we registered a net increase of slightly over 300 new members. This phenomenal growth of about 28% in three years was the result of the efforts of many dedicated members of the Society; but one person, Dr. C. T. Rogerson, must be singled out as having done much more than his share in bringing about our revival, if not our survival. Following a period of 13 months during which only one issue of bfycologia was published, Dr. Rogerson guided 21 issues of the journal through the press in 24 months, and Mycologia once again was appearing regu- larly by early 1963. His job having been done exceedingly well, Clark is resigning as Editor-in-Chief this summer. Dr. Robert W. Lichtwardt has consented to take on this de- manding task. I wish him well.

Several other items of business of considerable importance to the Society have been completed or brought nearer to completion during the past year. The MSA brochure -A Career -in Mycology has been revised by Dr. Beneke and his committee, Drs. Routien, Kneebone, and Shigo; it now is in the hands of the printer. Work on the Mycology Guidebook is progressing satisfactorily according to Dr. R. B. Stevens, Chairman of the Guidebook Committee, and he hopes by this fall to have a "first editionf' ready for trial by a few selected graduate students under the supervision of the various committee members (~rs. Barnett, Beneke, Emerson, Farr, Gray, Korf, and Simmons).

Of great significance to us all has been the revision of the Constitution which was a prerequisite for obtaining tax-exempt status from the Internal Revenue Service. The latter has been achieved; and this accomplishment is due almost entirely to the efforts of the Secretary-Treasurer, Dr. E. G. Simmons, who prepared almost two pounds of written doc- --- .

Dr. Donald P. Rogers, Department 0.f ~otan~,~~niversi€~of Illinois, is making the local arrangements for the /foray. . ,- - .. . . . , . , . Headquarters will be' maintained in!~oom408, Natural History Building, with a field trip departing from and returning to the campus each day. Library, laboratory, and drying facilities will be available. Individuals should provide their own collecting and pressing equipment.

Field trips are scheduled for full days on Friday and Saturday and for a long half-day on Sunday, August 13, 14, and 15. Several collecting sites are being considered, but final selection will be deferred until a few days before the foray. Dr. Rogers re- quests that all qualified medicine men engage in raindances about one week prior to the foray, with transference of their pluvial intentions to the east-central Illinois area.

Assembly'p6int, etc. The Fridaftrip will leave at 8:00 a.m. from the large parking area near .the Assembly Hall (not- from Natural History Bldg. ) . Check details Thursday night, if possible, ahddaily.thereafter.in the headquarters room. Chiggers are abundant in the Midwest during the summer; Dr. Rogers will have a supply of repellent, but bring your own if you have a proven favorite.

Transportation on all three days will'be by private cars. If you will have a car

at Urbana and can accommodate other passengers,- - . please- send tklis information to Dr. Rogers (see form below).

Meals. Box lunches will be available for all three days. Check details on ar- rival or certainly well'in advance of. 8:00 a.m. Friday. Breakfast and dinner will be on an individual basis.

Housing. University'housi.ng will be available. Preregistration and housing forms were distributed with the MSA call-for-papers and now are appearing in each issue of AIBS BioScience. Be certain that you have firm housing arrangements made before arriving in Urbana . 111. THE ANNUAL MEETING--1965. UNIVERSITY OF U;ELNOIS

The Annual Meeting will be held August 15-20, 1965, on the camp~~o~the University of Illinois, Urbana. Information on housing accommodations and food ser7aice.i~being pub- lished in current issues of AIBS BioScience. You are urged to preregister before July 16, 1965. The fee until July 16 for all registrants (except students) .is $10.00; $3.00 for students. The fee for delegates who apply for registration aRer July 16.is $12.00; $5.00 for students.

Dr. R. K. Benjamin will deliver his presidential address "The Merosporangium". The sixteenth annual lecture will be presented by Professor C. T. Ingold, Birkbeck College (university of t on don) , on the subject : "The Tetraradiate Aquatic Fungal Spore1'. Formal meetings of the Society begin on Monday, August 16. 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 arrange- ments 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 rep- resentative on program arrangements for the Mycological Society.

IV. MYCOLOGICAL SOCIETY GRADUATE FELLOWSHIP The Committee op Research Grants and Fublications, composed of-Drs,Alma W. Barksdale, Chm., Kenneth B. Raper, and Josiah L. Lowe, has selected Mr. AbrahamA. 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. MYCOLOGIA

Selection of a new Editor-in-Chief of MYCOLQGIA for the next five years now is in progress. It is expected that the final steps of selection will be completed in time for an appropriate announcement at the Annual Meeting. [~utsee Presidentts letter, @. 11

VII. MSA BROCHURE The final draft of a second edition of the Society's brochure "A Career in Mycology" now is complete and ready for the priqter. Some rewriting aqd.a few new il- lustrations should insure the quality of this popular publication. It is,expected that copies will be available for distribution by midsummer 1965. The revis3~n:haS been supervised by a committee of members Dr. Everett S . Beneke, Chm., : ~eonR';:fieebone, John B. Routien, and Alex L. Shigo.

VIII. GUIDEBOOK IN MYCOLOGY

The committee on preparation of the Society1s "Guidebook.-inMycologyf1 met 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: Life Members ...... 7 Regular Members ...... 951 Sustaining Members ...... 34 Affiliated Societies ...... 7 Corresponding Members ...... 1 Emeritus Members ...... 19 Associates ...... -57 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

AHEARN, Donald G., Frank J. REH, Jr., and Samuel P. MEYERS (university of Miami, Coral Gables, and Institute of Marine Science, Miami, la. ) Speciation and population studies of the indigenous yeasts of the Everglades. The taxonomy of yeasts occurring in virginal fk-esh, brackish, and true marine waters of the Everglades of Florida has been established. Studies have demo~stratedthat greater populations and diversity of species are present in fresh water locales than in other aquatic areas; however, certain sites in all of the major types of environments scudied showed yeast populations in excess of 2000 cells per .liter. Maintained cuitures evidenced a wide latitude of saline tolerances which failed to show correlation with the salinity value observed in their procurement site, although the salt concentration of the primary isolation medium had a profound effect on the num- ber of yeast co1oni.e~produced. As",~osporogenous forms and those yeasts with strong fer- mentative abilities were in highest frequency in the fresh water environs. By far the most commonly encountered taxa were Sry-ptococcus laurentii, Debaryomyces hansenii, and Rhodotorula glutinis.

AL-DOQRY, Yousef, and S . S . KALYEIi (Southwest Foundation for Research and Education, San Antonio, ex as) The mycoflora of the normal baboon. It is imperative that the nor- mal microbiological flora of the baboon be known since it has been recognized that this primate has good potential as ax experimental animal. In the present study, the mycoflora of three sites (rectum, vagina and skin) in one hundred normal baboon8 (papio sp.) was ex- amined. Sterile swabs were used to collect the specimens, after which they were streaked on plates of three differenc media (sabouraud9s Dextrose Agar, Brain Heart Infusion Agar and Mycosel). More than 800 fingal isolates were collected; about 400 of these were yeasts. The yeasts were mairiiy representatives of the genera Candida, Cry-ptococcus, Rhodotorula, Trichosporog,, --Geotrichwn and Saccharomyces. The pathogenicity of the various isolates of Candida d~inanspias a few other species of Candida was studied by using fe- male Swiss white mice for inoculation. An evaluation of the procedures and results is discussed.

AIEXOPOULCS, Constantine U. ('~,iniversity of Texas, Austin, ex as ) St,udies on two geo- firaphical races. of Gelasinospora autosteira Alexop. et Sun. 'Gelasinospora autosteira, a heterot4allic, bipol.ar ascomycete with octosporous asci, first described from Mississippi, was crossed with an isoi.ace from Costa Rica of what appears to be the same species. Perithecia are produced when either of the two mating types of each isolate is paired with either of those of the other isolate, but formation of asci and ascospores varies in different pairings. Results of the four crosses are presented.

BATRA, L. F.. , and Suzanne W. E&LL (~jniversityof Kansas, Lawrence, ~ansas) Fungus- rowing termites. The f'ungus-growing termites occur in Africa, South Asia and Australia fnd exclusively iive in mil. ' Inside their nests grow specific as well as non-specific hngi on a sponge-like nr.d brittle substratum consisting of minute pellets of excreta and termite carcasses. Roger Heim in 1942 studied many associations between fungi and termites from Africa found 10 species in the genus- Termitomyces Heim (~~aricaceae). In India we recovered Secotium, Armillaria, Collybia, Xylaria and some Fungi hperfecti from fungus gardens. Behaviour of these termites in relation to fungi is discussed.

13A,YTER, u'ohn W. (i~niversityof Wisconsin-,Milwaukee, Milwaukee, Wis .) Taxonomic problems -In Ravenelia and related genera of rust fingi. Recent studies of the genus Ravenelia indicate a need for a reappraisal of certain taxonomic characters, particularly the mor- phology of the cysts sgbtending the teliospore head. Some revision of existing termi- nology may be desirable, There is also s need for more emphasis on variation of" shape of aspmetrical urediospores. The taxonomic sit~ationin Ravenelia and related genera has been complicated f'urther by the discovery that several species are intermediate be- tween Ravenelia and Spurnula, one species is intermediate between Ravenelia and Ilicrchi- -dium? w.d a new rust species, recently collected in Nexico, is intermediate betwee?? Spumul-a and Hapalophragmiwn.

BENE,W, E. S . , and Flora MJID (~ichj.~a,nState University, East Lansing, Michigan) -Submerged cult-we studies of several species of Suillus. Different carbon sources were sukskituted in a basal medium to determine if tumor-inhibiting substances were produced in greater quantities by several species of Suillus under conditions of submerged culture. Assays were made by the use of sarcoma 180 in Swiss white mice.

BERLINEil, Martha D . , Peter W. NEURATH, and Barbara M. YANKOVICH (AVCO,RAI) Div. , Wijmington, Mass. ) -Control of rhythmic growth of a Neurospora "clock" mutant by sugars.- Xeurospora "clock" mutant CL lga, when gyoTm on certain agar media, forms clear growth rings at periodic time intervals. This report gives evidence for the chemical control of th2s rhythm. When grown or, an inorganic minimal medium containing 1%sucrose, growth is con5inuous without ring formation. men filter-sterilized dextrose, maltose and fruc- tose are s~bstitutedas the carbon source, well-defined bands which are due to branching and sub-branching of the hy-phae are formed. The linear growth rate remains constant; o~lythe pattern of branching is rhythmic. A sugar concentration between 0.1%and 2% is effective. ?/lacnose, lactose, raffinose, sorbose and glycerol in varjing concentrations were ineffective. The rhythmic pattern is also temperature dependent and light inde- pendent. Since the branching is the visible evidence of the rhythm, what we measure is the egd prodilct of a morphogenetic phenomenon many chemical steps removed from the cyclic or step-like chemical reactions controlling hy-phal branching. Morphological aberrations in Neurospora have been associated with changes in both the structure and the composition of the cell wall. This may indicate that the cause of the oscillations lles in the self- regulation of biochemical syntheses rather than in external physical factors, altho?~gh these ir some instances may interact and control the period.

BLSTIS, George N. (!Yew York Botanical Garden, Bronx, N. Y,) -Some aspects of" the process of dikaryotizstion in Clitocybe truncicola. In the tetrapolar basidiomycete Clitocybe ----truncico1.a the process of dj-karyotization has been studied in living material by micro- scopic observation of compatible mating~. The nuclei in such material were visualized by (1) growing and/or mounting the fungus in 15-20% gelatin medium and (2) observing tkr.rough a phase contrast microscope. The process of dikaryotization was studied in both oidium X mycelium and mycelium X mycelium cohtrasts; the following stages were cxerved: (1) the origin of hyphal branches (fusion hy-phae) on the mycelium and their grow.tln to individual oidia, (2) fusion of an oidium and a fusion hypha, (3) the breakdown of some of the septa of the main hypha that gave rise to the fusion hy-pha, (4) the delayed ap- pearacce of the dikaryon, i,e., hyphae bearing clamp connections, (6) the concomitant abnormal growth of the homokaryotic hy-phae, (7) the retardation of the linear growth of the colony during stages (5) and (6).

BRUMC, Marq and H. L. EWNETT (west Virginia University, Morgantown, W. Va.) Parasitism and host ranges of Dispira simplex and D. parvispora. Dispira simplex Benjamin and D. parvispora Benjamin are similar morphologically but they have completely d-ifferert host ranges. Both species produce special branches which penetrate host hy-phae by infection pegs and form haustoria. The known hosts of D. simplex are limited to 11 species of Chaetomium. All other mgi tested, includin; 15 species of Mucorales, were immune. D. parvispora parasitized 7 species of Mucorales and Monascus purpureus. Concentrations rf glucose and yeast extract were critical in determining susceptibility of hosts to their respective parasites. 2. parvispora made slow axenic growth on agar media containing yeast extract, but sporulation was abnormal.

BURMEISTER, H. R., and C. W. HESSELTINE (~orthernRegional Research Laboratory, Peoria, Illinois) Microorganisms inhibited by aflatoxin. Aflatoxin-sensitive microorganisms may facilitate future studies concerning the mechanism of toxicity; and the development of a microbiological assay should supplement chromatographic deternat ions. several hundred microorganisms were screened to determine their reaction to aflatoxin. Some species of several genera of bacteria are inhibited by 5-30 pg/ml of the combined aflatoxins when incorporated into the growth substrate. The most sensitive strains are being tested for possible use in an assay.

CARMICHAEL, J. W. (university of Alberta, Edmonton, Alta. ) Similarity and undifference. The idea that overall similarity is some kind of sum of a number of qualitative, one- dimensional similarities has proved usef'ul. It would be even more userul if the one- dimensional similarities could be quantified. This can be accomplished by considering similarities as being ratios of undifferences.

COOKE, W . Bridge (~obertA. Tart Sanitary Engineering Center, Cincinnati, 0hio) Fungi in sludge digesters.

DAVIDSON, Ross W. (colorado State University, Fort Collins, ~olo.) Two interesting new species of Ceratocystis from conifers. Ceratocystis abiocarpa, a large perithecial species, is common in subalpine fir killed by Dryocetes confusus Sw. bark beetles in the central Rocky Mountain areas from northern Arizona through Wyoming. It also occurs in Englemann spruce logs on trees infested by Ips spy. bark beetles but is not associated with the common Dendroctonus engelmani Hopk. The other species, C. seticollis, is known from only one culture isolated from ambrosia beetle galleries in Fapwood of a stump of recently cut hemlock tree in eastern New York. Perithecial morphology of this species is striking and differs from any previously described.

EL-ANI, Arif S. (~ewYork State Department of Health, Albany, N. Y.) Leptosphaeria tompkinsii, a new species and etiologic agent of mycetoma. Leptosphaeria tompkinsii was isolated from a Mauritanian patient in Paris by Segretain and his associates, who de- scribed it as a new strain of L. senegalensis. However, comparative morphological in- vestigations carried out on the new isolate and on five strains of L. senegalensis re- vealed that the ascospores of the former are so different from those of the latter as to justif'y establishing a new species. The.ascospores of L. senegalensis are 4-septate (rarely 5- or 6- septate), 23-30 x 8-10 w; each ascospore Fs surrounded by a turbinate gelatinous sheath bearing a basal satellite. In the new isolate the ascospores are larger, 33-45 x 8.8-11 p, and are 4-8 septatey,with 6- and 7- septate ones being most common. The sheath is almost uniform in shape and the basal satellite is lacking. Thus a new species differing fr0m.L. senegalensis in spore size and septation and in the form of the gelatinous sheath was established as L. tompkinsii in the honor of Dr. Victor N. Tompkins, Director of the Division of"~aboracoriesand Research and Professor of Pathology, Albany Medical College, for his inspiring association and profound interest in mycoses.

ELLIS, J. J. (~orthernRegional Research ~aboratory,Peoria, ~llinois) Procedure and conditions for the growth of Syncephalis in pire culture. Cultures of Syncephalis can be maintained on a complex organic medium in the absence of a f'ungal host. Optimum tem- perature and pH ranges were investigated as were possible carbon sources'

EMBREE, Robert W. (~rownUniversity, Providence, R. I.) . An aquatic Mucor. An undescribed mucoraceous Fungus growing and sporulating on submerged insect pupae is reported. iii ENGLAND, Wayne H. (west Virginia University, Morgantown, W. 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 mod- ified 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 mycopara- sites (~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-per- parasite of Isaria acaricida Pat., a fungus described as growing on spiders on Chusquea leaves. The present~emonstratesthat D. allogena and I. acaricida are superficial stages of one fungus which possesses a well-developed hypostroma and belongs in Anten- nularia (~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-thium sp. 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 .

HACSKAYLO, E.) and J. G. PflLMER (u.s.D.A. Forest Physiologq Laboratory, Reltsville, Md. , a~.dForest Disease Laboratory, Laurel, Md.) Carbon sources utilized by ectotrophic mycorrhizal fungi. As part of a continuing study on the physiology of six isolates of ectotrophic mycorrhizal fingi, several carbon compounds were tested for utilization.

EAJYKS, David L,, and A. S. SUSSAMAN (university of Michigan, Ann Arbor, ~ichigan) Treha- lose metabolism and conidiation in Neurospora. Wild type and mutant strains of Reuros~ora-- crassa which produce conidia exhibit a relatively high level of trehalose ,activity. In contrast, extremely low activity is found in aconidial strains. 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. The results are dis- cussed in terms of possible models linking trehalose formation and conidiation.

HENNEY, Mary R. (university of Texas, Austin, ex as) Multiple allele heterothallism in Physarum flavicomum and Physzrum polycephalum. Studies of single spore isolates from two collections of Physarum flavicomum and of Physarwn polycephalum, one of" each from Texas and from Costa Rica, proved these organisms to be heterothallic. Hybridization experiments between the Texas and Costa Rica isolates revealed the existence of multiple alleles in both species. Attempts to produce interspecific hybrids have failed so far.

Il'JGOXl, C . T. irkbe beck College, University of London, London, ~n~land)The Tetraradiate 'Aquatic Fungal Spore. Sixteenth Annual Lecture. KERN, Frank D . (~ennsylvaniaState University, University Park, Pa. ) The Uredinales of Puerto Rico. The rust f'ungi as they occur in Puerto Rico have been objects of special study by several collectors and investigators. Extensive collections have been made by Stevens; Whetzel and Olive; and Whetzel, Kern and Toro. Other collectors of note are Chardon, Clinton, Stevenson, Holway, and Roure. Published reports are to be found by Arthur (Mycologia 71168-332, 1915; 8:16-33, 1916; 2: 55-104, 1917), by Kern & Whetzel (Mycologia 18:39-47, 1926; Sci. ~urrPuerto Rico and the Virgin Islands 8:111-114), and by Rome (TE~.Paper 35, Univ. of Puerto Rico, Agric.

For some time an effort has been put forth to bring all available records down to date as regards addi- tional data and changes in classification concepts and particularly to make the nomen- clature of both rusts and hosts comply with the present International. Code. A resume is presented . KLOOS , Floris , and Lois TIFFANY (1owa State University, Ames , 1owa) Ascocarp development in Hypocrea sulphurea.

LICHTWAFDT, Robert W. (university of Kansas, Lawrence, ~ansas)Cultures of Trichomycetes from Hawaii and Japan. Several dozen axenir: isolate-A representing a number of species of Smit tium (~arpellales) and Amoebidium (~moebidiales) were obtained from Diptera larvae in Hawaii and Japan. Evidence suggests that some of these Trichomycetes may be spread by adult insects, though the mechanism by which this is accoqlished is not known.

LICH'TWARDT, Robert W. , Hiroharu INDOH, and Yosio KOBAYASI (university of Kansas, Lawrence, Kansas; Tokyo University of Education; and National Science Museum, Tokyo, ~a~an)*-D&-- tribution of Trichomycetes in Japan and Taiwan. The Trichomycetes are widely distributed in Japan, as indicated by collections of arthropods from various types of habitats on the islands of Honshu, Hokkaido, and Shikoku. Additional limited collections were made in Taiwan. Species representing all major taxa of Trichomycetes were found and studied. The most striking general observation was the similarity of most genera, and some species, to those of the United States and Europe. In addition, a certain lack of host specificity in some widely distributed- species suggests that cautTori'should be-exercised in differ- entiating genera and species of Trichomycetes,primarily on the basis of their hosts.

MERZ, W. G., and V. G. LIUY (west Virginia University, Morgantown, W. Va. ) Effects of light on sporulation of heterothallic species of Phytophthora. Crosses of Phytophthora capsici,.P. drechsleri, P. nicotianae, 2. pdmivora, and P. parasitica were found to pro- duce more sporangia in lyght than in darkness. Oospores were- only in darkness or in low intensity light. In this study,,a flood plate method of inoculation was used so that sporangia and oospores could be counted. In interspecific crosses oospores were produced only in darkness. Using filters, blue light stimulated the production of spo- rangia and inhibited the production of oospores, while longer wavelengths were less in- hibitory on oospore production and more inhibitory on sporangial. production. These ex- periments were conducted on a half-strength lima bean medium.

OLIVE, L. S ., and Cakmen STOIANOVITCH (~olumbiaUniversity, New York, N. Y. ) A simple new mycetozoan with ballistospores. The vegetative phase of this organism is a plas- modium, which fragments into rmiitinucleate prespore cells, each of which gives rise directly to a multinucleate spore on a short stalk. The small fruiting body closely resembles that of Cavostelium apophysatum, but the spore is discharged by explosion of a gas bubble. There is no evidence of a sexual phase, and zoospores are not produced.

RIDINGS, W. H., M. E. GALLZGLY, and V. G. LIUY (~es's'f,Virginia university, Morgantown, W. Va. ) -~hiami&requirements as a means of distinguishing Pythium from Phytophthora species. Twenty-two species of F'ythium (69 isolates) were studied. All available iso- lates of Wthiwn helicoides, P. oedochilum, P. oligandrum, P. proliferans and P. stellatum were deficient for the pp-imizine moiety of Thiamine. One Tsolate each of P. ~raminicolum and P. undulatum was deficient for pyrimidine whereas the other isolates were self-suf- ficient. All isolates of P. vexans required intact thiamine for growth. All of the iso- lates tested of -P. aphanid&matum, -P. aristosporwn, -P. arrhenomanes , 2. catenulatum, -P. debaryanum, g. deliense, g. irre ulare, P. mammilatum, P. paroecendrum, P. polymoqhon, -P. rostratum, g. splendens, -P. -€--ul imum, anddP.- sp. were self-sufficient for-thiamine. RUTHERFORD, Thomas C . a as t Carolina College, Greenville , N. C . ) Some aquatic lignicolous fungi of southwestern Virginia. Fungi on wood were collected from various aquatic sites in the area of Blacksburg, Virginia. The following fungi were identified: Alternaria sp., Bisporomyces chlamydosporis, Cacumisporium sp., Dictyosporium elegans, Dictyosporium sp., Gonytrichum macrocladum, Humicola sp.)Leptographium sp., Monotospora megalaspora, Piricauda sp., Septonema hormisci~,5. secedens, Sporidesmium caespitulosum, S. anglick, Sporos- chisma saccardoi, Trichocladium opacum, Nocardia sp., Arthrobotrys SF., Clathrosphaerina zalewski, F'usarium solani, Helicomyces roseus, Hobsonia mirabilis, Verticillium sp., Bactrodesmium arnaudii, A os haeria agminalis, Asteromella sp., Coniothyrium sp., Stagonos- pora sp.

SIERRA, Ruth N., and Norvel M. MC CLUN,G (university of Georgia, Athens, Ga.) Studies on the production of cleistothecia by Nannizzia sp. on synthetic media. A number of combina- tions of vitamins, amino acids, minerals,.and trace elements proved to induce the forma- tion of cleistothecia by Nannizzia incurvata and N.-gnsea but failed to stimulate the formation of ascocarps in N. f'ulva. Cleistothecia were produced faster in the vitamin supplemented synthetic med&n than in soil baited with hair. The number of cleistothecia was greater in the synthetic medium for N. vsea but no greater for the other two.species. After 12 days of incubation the number of cleistothecia was similar in all media tested. The effects on growth and cleistothecial formation of components of the synthetic medium were tested.

SPARROW, F. K. (university of Michigan, Ann Arbor, Mich. ) Further studies in Physoderma. STOIANOVITCH, Carmen, and L. S . OLIVE (~olumbiaUniversity, New York, N. Y .) A new protostelioid genus of mycetozoa intermediate between Cavostelium and Protostelium. Two new single-spored species of mycetozoa resembling Protostelium have been found, one with spherical and the other with oblong spores. The vegetative stage is a plasmodium which fragments into multinucleate prespore cells that give rise to multinucleate spores on long, slender stalks. The spores are deciduous. Sexual reproduction and zoospores are unknown.

TABAK, Henq, and Wm. Bridge COOKE (~obertA. Tart Sanitary Engineering Center, Cincinnati , 0hio) Growth of fungi in oxygen-free.atmospheres. The occurrence of filamentous fungi in relatively large numbers in habitats devoid of measurable oxygen in sewage treatment sys- tems posed the question of the ability of fungi ta survive, metabolize, and grow under such conditions. Liquid media containing sugars and asparagine or aLnmonium nitrate, with and without sodium formaldehyde desulfoxylate, in 25 ml cotton-stoppered conical flasks, were inoculated with liquid-grown, finely chopped, washed cells and were incubated in ana- erobic jars. The jars were evacuated and filled with 100% nitrogen gas. Growth was de- termined after 1, 2, 3, and 4 weeks by oven dry weights of cells collected on membrane filters and by determination of combustible residual organic carbon. Appreciable growth was obtained from strains of all species tested to date.

THERRIEN, C. Dale (university of Texas, Austin, Texas) Microspectrophotometric analysis of nuclear DNA in some Myxomycetes. Microspectrophotome~ricanalysis of nuclear DNA in several heterothallic species of Myxomycetes reveals that the nuclei of the spores and myxamoebae contain half the amount of DNA found in the plasmodial nuclei. It was demon- strated that in some species the two mating types differ in the nuclear DNA content. DNA is shown in absolute amounts of DNA per nucleus. The Feulgen nucleal reaction was used in conjunction with absorption microspectrophotometry to measure the DNA. THIERS, Harry D. an Francisco State College, San Francisco, calif. ) The genus Suillus in California. WAGNER, Diane Testrake (~ukeUniversity, Durham, 'N. C .) Incidence of a graminicolous salt marsh fungus. Leptosphaeria discors Sacc. & Ell. occurs commonly on dead culms of Spartina alterniflora Loisel in-the salt marshes of Beaufort, N. C. Geographical distribution of this fingus and the common host is noted in addition to their seasonal occurrence. The spatial relationship of the Fungus in S. alterniflora is investigated. Two methods of sampling were employed to study the intertidal distribution of L. discors. Observations of its distribution in an estuary are made with reference to a horizontal salinity gradient.

WATSON, Alice J. (~ationalFungus Collections , Plant Industry Station, Belt sville, Md .) Latent infections in citrus fruit. Experiments were conducted at Beltsville, m., to determine latent infections of citrus fruit from South Africa, Florida, and California. Black spot of citrus rind caused by Guignardia citricarpa, [fibma- citricarpa stage) was found latent in oranges from South Africa. The Florida fruit did not show this black spot fungus, but it did carny a Cercospora sp. close to Cercospora citri-grisea, previously only reported from the leaves. California fruit rind contained latent infections of Alternaria .- citri but no black spot Mgus. All fruit showed latent infections of Colleto- trichum gloeosporioides.

WELLS, Kenneth (university of California, Davis. Calif. ) Some Tr~mellalesfrom southern Brazil. The morphological characters of several rare or new species of Tremellales from the vicinity of S;Zo Paulo, Brazil, are discussed. These include Martin, known from Ontario and Iowa; Exidiopsis figacissima Trott., known from North America and Europe; Exidiopsis candida (olive) Wells; an unde- scribed species of Exidiopsis ; Heterochaete tremellispor~.) Bodman, known only from Blumenau, Brazil; and Hyaloria pilacre Mdll., known from Blumenag, Brazil, and Colombia.

The spore to spore cultivation of a new species of Comatricha (C. nodulifera) is reported on several types of agar media. Size of fructification and dTameter of sporangium are variable, but the capillitial characters, which distinguish this species from all others, appear to be constant. The plasmodium is, as'expected, an aphanoplasmodium. Preliminary work indicates that the organism .is hetirothallic, plasmod?a and fruiting bodies being formed only when compatible myxanoebal clones, derived from single spores, are mated.
