STUDIES ON THE MATING SYSTEMS OF ELEVEN SPECIES OF MYXOMYCETES

Genetic analysis of 20 isolates representing 11 species of Myxomycetes was carried out to determine whether they were heterothallic or homothallic. Each of the single isolates of Badhamia utricularis, Didymium minus, D. nigripes, and Physarum cinereum was found to be heterothallic, the first such reports for all of the species except D. nigripes. All isolates of Badhamia foliicola (1), Didymium squamulosum (1), Physarum compressum (3), P. gyrosum (1), P. pusillum (2), Stemonitis flavogenita (6) and an unidentified species of the order Physarales (2) were homothallic, with B. foliicola, P. compressum, and S. flavogenita being reported for the first time.

Delineations of forest fungi

Summary Several forest fungi, primarily species that occur in Mississippi, are discussed, and three species are described as new. These includeBotryobasidium (subgenusBrevibasidium)croceum Lentz,Tharoopama mississippiensis Lentz, andHarpographium zonatum Lentz.Dactylium leptosporum (Sacc.)Lentz is recognized as a distinct species, rather than as a subspecies ofD. dendroides Fr. Allescheriella crocea (Mont.)Hughes,D. leptosporum andMelanographium cookei M. B. Ellis are reported from Mississippi for the first time. Attention is called to the fact thatM. citri (Fragoso &Ciferri)M. B. Ellis apparently has not previously been reported from the United States, although a specimen from Florida is in the National Fungus Collections.B. croceum evidently represents the basidiophorous stage ofA. crocea.     

THE LABORATORY CULTIVATION OF STEMONITIS

Alexopoulos , Constantine J. (State U. Iowa, Iowa City.) The laboratory cultivation of Stemonitis. Amer. Jour. Bot. 46(2): 140-142. Illus. 1959.—The cultivation of a species of Stemonitis, probably S. flavogenita, in laboratory culture is reported here for the first time. The organism completed its entire life cycle on artificial media from spore to spore, in the presence of contaminating bacteria, in 36 days. The plasmodium, characteristically different from those of the Physarales, is described and illustrated.     

Heteromerikarpie und Fruchtpolymorphismus beiMicroparacaryum,gen. nov., (Boraginaceae)

Microparacaryum (M. Pop. exH. Riedl)Hilger & Podlech is described as a new genus of theBoraginaceae-Cynoglosseae. It comprises the annual species hitherto included inParacaryum (DC.)Boiss. andMattiastrum (Boiss.)Brand. Distribution maps are given for all 3 genera.Microparacaryum consists of two species,M. salsum (Boiss.)Hilger & Podlech (M. s.) andM. intermedium (Fresen.)Hilger & Podlech (M. i.). ParticularlyM. i. is a very variable species, and most of the species formerly recognized belong here. Scattered all over the range of the genus, plants occur with nutlets exhibiting flat or incurved marginal wings, often in mixed populations. This fruit polymorphism is taxonomically treated by recognizing formae. In addition, the following new infraspecific taxa and combinations are described:M. i. var.intermedium formaparacaryoides Hilger & Podlech,M. i. var.stellatum (H. Riedl)Hilger & Podlech,M. i. var.stellatum formamattiastroides Hilger & Podlech,M. s. formamattiastroides Hilger & Podlech.

     

Nutritional studies on species and mutants of Lepista,Cantharellus, Pleurotus and Volvariella

The purpose of this study is to determine the ability of select Agaricales species to utilize various sources of carbon, nitrogen, vitamins, and growth hormones. Fungi selected for the studies include:Cantharellus clavatus Fries,C. cibarius Fries,Lepista nuda (Bull. ex. Fries)Cooke,Pleurotus ostreatus (Jacq. ex. Fries)Kummer, andVolvariella volvacea (Bull. ex. Fries)Singer. Three strains ofC. cibarius and one mutant ofV. volvacea (V135), V134, were employed to determine if nutritional requirement differences occurred. One species,V. volvacea, is grown commercially as a cottage industry in the Orient (Alicbusan &Ela, 1961) while the other species currently have no commercial value. All species studied possess pleasing flavors and have potential use in the mushroom production industry.A literature compilation of the nutritional regulation of basidiocarp formation and vegetative growth of Agaricales was made with specific mention to the named species (Volz &Beneke, 1969). Recent nutritional studies with one or more of the specific species include those byYusef &Allam (1967), andEger (1970).

Paleobotanical studies inFagaceae of the European Tertiary

A systematic reassessment of megafossil records ofFagaceae in Central Europe has been undertaken on the basis of leaf cuticular characters. The oldest representatives date back to the Eocene:Quercus subhercynica spec. nova,Dryophyllum furcinerve (Rossm.)Schmalh.,Trigonobalanopsis rhamnoides (Rossm.) gen. & comb. nov. In the Oligocene other members of extant genera appear:Quercus rhenana (Weyl. & Kilpp.)Knobloch & Kvaek,Fagus attenuata Goepp.,Lithocarpus saxonicus spec. nova. In the Neogene these ancient taxa (except inFagus lineage), are gradually replaced by deciduous species ofQuercus andCastanea. Trigonobalanus andCastanopsis are recorded by fruits (or wood) only.     

Oxfordian perisphinctid ammonites from Chacay Melehué, Argentina

A significant assemblage of Oxfordian perisphinctids was collected at Chacay Melehué, Neuquén, Argentina. It is composed of well preserved specimens belonging to the family Perisphinctidae:Perisphinctes aff.promiscuus Bukowski (Perisphinctinae),Tenuisphinctes herreroduclouxi (Leanza) (Perisphinctinae), andSubvinalesphinctes pseudokranaus n. sp. andS. prophetae (Gygi & Hillebrandt) (Vinalesphinctinae). The family Ataxioceratidae is represented byLithacosphinctes aff. janus (Choffat) (Ataxioceratinae). The subfamily VinalesphinctinaeMeléndez & Myczynski, 1987 is discussed and organized into three genera:Subvinalesphinctes Wierzbowski,Vinalesphinctes Spath andCubasphinctes Judoley & Furrazola, which seems to cover the whole of the subfamily, ranging, at least, from the lowerplicatilis to the lowerbifurcatus zones, Middle Oxfordian in Cuba, part of Mexico, Chile and Argentina. The root of the subfamily is most likelyS. pseudokranaus n. sp. The paleobiogeographic affinites are mainly Tethyan, and Tethyan-Caribbean during the Middle Oxfordian.

Fungi causing plant diseases at Jabalpur (M.P.) XI

Summary In this paper eight foliicolous fungi have been described from Jabalpur (M.P.) India.

The utilization of the mixtures of monosaccharides by some mucorales

Summary The utilization of mixtures of monosaccharides byBlakeslea trispora Thaxter,Choanephora circinans (Naganish &Kawakami)Hesseltine &Benjamin,Gilbertella persicaria var.indica Mehrotra &Mehrotra andHelicostylum piriforme Bainier was studied. The effect of sorbose on the utilization of other sugars present in the mixtures was also studied. It was found that all the mixtures of sugars in combination with asparagine or ammonium chloride were valueless for all the organisms exceptHelicostylum piriforme. Growth ofHelicostylum piriforme on the mixtures with asparagine as the nitrogen source was better than on the mixtures with ammonium chloride as the source of nitrogen. Asparagine being a favourable source counteractecd sorbose inhibition, while ammonium chloride failed to do so. On the other hand, both of the nitrogen sources failed to counteract sorbose inhibition in the rest of the organisms. None of the organisms could finish sorbose and rhamnose from any of the mixtures within the specified period.     

Effect of prior vaccination on experimental Blastomycosis

Immunogens were found associated with particular fractions prepared from spherules ofCoccidioides immitis (Kong, Levine &Smith, 1963) and from yeast cells ofHistoplasma capsulatum (Salvin &Ribi, 1955). However,Blastomyces dermatitidis, another dimorphic systemic fungal pathogen was shown to elicit a minimal immunogenic response in experimental animals (Kong &Levine, 1967). It was therefore deemed pertinent to study factors which might enhance the resistance of mice to infection withB. dermatitidis.
