Comments on this species from the comments on Observation 5079:
Matthew Keirle says “Parasola leiocephala closely resembles P. plicatilis, but is readily distinguished in that it has significantly smaller basidiospores that exhibit a more consistently central germ pore and by the fact that it is found in soil associated with woodchips in parks, not in grass.” Parasola plicatilis seems to always be in grass.
