Summary

A taxonomic study was made of morphological variability in several cultures ofGymnoascus reessii isolated from dung and soil, mostly in California. There is considerable variation among isolates of this species with regard to cultural and ascocarp characters such as the nature of the free apices of the peridial hyphae. Ascospore characters are quite stable. Although certain isolates possibly could be grouped into varieties, such groupings merge into one another. Hence, at this time it appears that varieties ofG. reessii cannot readily be distinguished. The single heretofore described variety,G. reessii var.deilephilae Hennings, is reduced to synonymy withG. reessii Baran.
