Tulosesus is a genus of fungi in the family Psathyrellaceae.
The Tulosesus genus was created in 2020 by the German mycologists Dieter Wächter & Andreas Melzer when the Psathyrellaceae family was subdivided based on phylogenetic analysis. Many members of the Coprinellus genus were reclassified as Tulosesus. The type species, Tulosesus callinus was previously classified as Coprinellus callinus.
This genus name is an anagram of setulosus, Latin for having coarse hair or bristles.
