Field notes

Coprinellus is a genus of mushroom-forming fungi in the family Psathyrellaceae. The genus was circumscribed by the Finnish mycologist Petter Adolf Karsten in 1879. Most Coprinellus species were transferred from the once large genus Coprinus. Molecular studies published in 2001 redistributed Coprinus species to Psathyrella, or the segregate genera Coprinopsis and Coprinellus.

In 2020, phylogenetic analysis conducted by the German mycologists Dieter Wächter & Andreas Melzer reclassified many Coprinellus species as belonging to the new genus Tulosesus.
