# List of Psathyrella species

This is a list of Psathyrella species. Many of its members were formerly classified in the genera Hypholoma, Psilocybe, and Stropharia. Also some well-known species have been moved to new genera, for instance Psathyrella spadicea is now Homophron spadiceum. Lacrymaria lacrymabunda has often been classified as a Psathyrella. According to one 2008 estimate, the genus contains about 400 species.
In 2020 many members of the family Psathyrellaceae were reclassified by the German mycologists Dieter Wächter & Andreas Melzer based on phylogenetic analysis. This study created the new genera Britzelmayria, Candolleomyces and Olotia and placed numerous former Psathyrella species within them. Notable changes include Psathyrella candolleana being reclassified as Candolleomyces candolleanus and Psathyrella multipedata being reclassified as Britzelmayria multipedata.

## Species
