ABSTRACT
The distribution and relative abundance of coprophilous Ascomycetes having certain ascocarp morphologies [e.g., cleistothecium; multi-spored ascus (> 8 spores), and distinct bristles or hairs on neck of perithecium] was contrasted for rabbit and cattle feces collected from a semi-arid short-grass prairie, a mixed-grass prairie, and a tall-grass prairie. Species with non-ostiolate ascocarps were most frequently recorded from dung in semi-arid short-grass prairie (p < 0.05); species producing multi-spored asci were more frequently recorded on dung from the mesic prairie (0.10 > p > 0.05); and species with bristles or hairs on the perithecial neck and surrounding the ostiole showed no significant variation among prairies.
