Coprinellus disseminatus, formerly known as Coprinus disseminatus and commonly known as the fairy inkcap, fairy bonnet, or trooping crumble cap, is a species of agaric fungus in the family Psathyrellaceae. Unlike most other coprinoid mushrooms, C. disseminatus does not dissolve into black ink (deliquesce) in maturity. The species was given its current name in 1939 by Jakob Emanuel Lange. Coprinellus disseminatus has about 143 sexes (mating types). The species is nonpoisonous.
