Protostropharia, is a coprophilous agaric fungal genus that produces glutinous, mostly yellowish to yellow brown fruit bodies. Characteristically most form chrysocystidia and rather large, smooth, violaceous basidiospores each with a prominent germ pore (as Stropharia subg. Stercophila [1] [2] ). It is differentiated from Stropharia by production of astrocystidia on its mycelium rather than by acanthocytes that Stropharia produces. [3] [4] [5] [6] Phylogenetically, Protostropharia is distinct from Stropharia, Pholiota , and Leratiomyces . [7] [8] Two species, P. luteonitens and P. tuberosa , form pseudosclerotia within the dung substrate. [9] [10]
The name Protostropharia refers to the less anatomically complex astrocystidia (Greek proto-) as compared to the acanthocytes in Stropharia .
