Studies of coprophilous Ascomycetes. I. Gelasinospora.

Abstract

Two species of Gelasinospora are described for the first time. G. adjuncta Cain, a heterothallic species with eight-spored asci, was grown in moist chambers on dung from Germany and Quebec. G. retispora Cain, distinguished by means of the large angular pits in the ascospore wall was isolated in culture from seeds of Swiss chard from Holland and from apple twigs in Quebec. G. tetrasperma Dowding has been found in moist chambers on dung from Ontario, Quebec, Venezuela, and Germany and isolated from seeds from Quebec. Notes are added regarding the disposition of Anthostomella destruens Shear and Sordaria uvicola Viala and Marsais.
