Protostropharia
Protostropharia Redhead, Moncalvo & Vilgalys, in Redhead, Index Fungorum 15: 2 (2013)
Etymology: Proto- (early), Stropharia.
Diagnosis: Distinguished from Stropharia by the formation of astrocystidia rather than acanthocytes on mycelium including that at the bases of basidiomes and in cracks and pockets within the dung substrate. Protostropharia astrocystidia consisting of short branch hyphae bearing terminal globose heads of sharp, coarse hyaline crystals (presumably calcium oxalate) in contrast to the encrusted dendroid hyphal ends bearing a stellate mass of needle sharp and shaped crystalline branches characteristic of true acanthocytes formed by Stropharia sensu stricto. Coprophilous. Pileus and stipe glutinous. Basidiospores smooth, thick-walled, with a germ pore. Pleurocystidia are chrysocystidia. Clamp connections present
