Abstract
The discovery of homothallism and heterothallism in the Mucorales by Blakeslee (2), in the Eubasidiomycetes by Kniep (8), Mlle. Bensaude (1), andothers, in the Rusts by Craigie (3), in the Smuts by Hanna (6), and others, and in the Ascomycetes by Dodge (4), Edgerton (5), etc, has led the writer to undertake further studies in the Ascomycetes. This paper presents some work that has been done on a few coprophilous Ascomycetes. Single spore cultures were made in all cases and matings in all combinations were employed in the study of the sexuality of these fungi. The cultures were all grown on agar in petri dishes at room temperature. Single spore cultures were obtained by a dry needle method similar to that described by Hanna (7). It was found helpful in germinating the spores of Ascobolus to treat them first with a warm solution of dilute HC1 for five or ten
