Britzelmayria Coprinellus Coprinopsis Cystoagaricus Gasteroagaricoides Homophron Hormographiella Kauffmania Lacrymaria Macrometrula Narcissea Olotia †Palaeocybe Parasola Psathyrella Punjabia Tulosesus Typhrasa The Psathyrellaceae are a family of dark-spored agarics that generally have rather soft, fragile fruiting bodies, and are characterized by black, dark brown, rarely reddish, or even pastel-colored spore prints.
Prior to phylogenetic research based upon DNA comparisons, most of the species that autodigested were classified as Coprinaceae, which contained all of the inky-cap mushrooms.
It is characterized by rough basidiospores and lamellar edges that exude beads of clear liquid when in prime condition, hence the Latin reference, lacryma (tears).
Most Psathyrellaceae basidiospores have germ pores, and the pigment in the spore walls bleaches in concentrated sulfuric acid.
The species Coprinopsis cinerea is a model organism for mushroom-forming Basidiomycota, and its genome has recently been sequenced completely.
