Psathyrella (les Psathyrelles), est un genre de champignons basidiomycètes de la famille des Psathyrellaceae.
Ce genre comporte une centaine d'espèces, semblables phylogénétiquement aux genres Coprinellus et Coprinopsis, et proches morphologiquement des Coprinus et Panaeolus.
C’est le premier genre connu dont une espèce possède des lames qui sont capables de sporuler sous l'eau : Psathyrella aquatica.

## Description du genre (sensu lato)
