Protostropharia
Genus of fungi
From Wikipedia, the free encyclopedia
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]

Etymology
The name Protostropharia refers to the less anatomically complex astrocystidia (Greek proto-) as compared to the acanthocytes in Stropharia.
