Rhacophyllus lilacinus was obtained in moist chamber from bark collected in Austin, Texas. A perfect state of an undescribed fungus, Coprinus clastophyllus sp. nov., developed in laboratory culture from R. lilacinus. Some morphologic, cultural, cytologic and genetic features of both states are discussed and illustrated.
Analysis of crosses between granular and downy self-sterile strains of Arthroderma benhamiae ( = Trichophy ton mentagrophytes var. granulosum) displaying high and low extracellular elastin-hydrolysing capabilities indicates that the locus for mating-type segregates independently of a colonial morphology locus and a locus determining elastin-hydrolysing capability. The colonial morphology locus consists of two alleles which govern the production of granular or downy phenotypes, and is closely linked to a locus consisting of two alleles which determine high or low extracellular elastolytic activity, showing a recombination frequency of approximately 5 yo.
Fields, William G., and James Maniotis. (Wayne State U., Detroit, Mich.) Some cultural and genetic aspects of a new heterothallic Sordaria. Amer. Jour. Bot. 50(1): 80–85. lllus. 1963.— Sordaria heterothallis sp. nov., isolated from rabbit dung collected in Austin, Texas, is characterized as a spermatium‐prcducing, hcterothallic Sordaria with carbonous stromatic walls. Spermatia may germinate, but their low frequency of germination suggests their role in asexual reproduction is minor. The fungus was determined to be biotin‐ and thiamine‐deficient. A single pair of factors about 1.9 units from the centromere governs compatibility. Ordered tetrad analyses indicates regular segregation of factors for ascospore germination, the production of aerial mycelium and pigmentation. Intra‐ and intergeneric reactions stimulating protoperithecial production occurs between Sordaria heterothallis and the related species Sordaria brevicollis and Gelasinospora atilosleira.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
