Almost all modern sources consider T. myomyces to be a synonym of T. terreum,[6][7][8] but there are some exceptions. Bon mentions that T. myomyces has been defined for lowland mushrooms with white gills and a fleecy cap.[9] Courtecuisse separates it on a similar basis: the cap surface is felty and the gills are whitish and more crowded.[10] Moser distinguished T. myomyces on the basis that the gills should go yellow.[11]
The gray cap is 2–5 cm wide. The whitish stalk is 2–5 cm long and .5–1 cm wide. It has white spores.[12]
