F ields , W illiam G., and J ames M aniotis . (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.
