SUMMARY
Ascocarps of Eleutherascus peruvianus, a simple ascomycete isolated from soil from Peru, consist of only one to two (rarely three) asci and a few sterile hyphae. The asci are without a peridium, globose to subglobose, and typically 8-spored. The ascospores are brownish, globose to subglobose, and ornamented with spines, short ridges, and a longitudinal ridge. Eleutherascus peruvianus differs from the type species, E. lectardii, in cultural characters and ornamentation of ascospores. Although Eleutherascus is retained in the Plectomycetes near Arachniotus and Amauroascus, it relates in some characters to Ascodesmis in the Discomycetes.
