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. About 50% of species produce fruiting bodies that dissolve into ink-like ooze when the spores are mature via autodigestion. 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. However, the type species of Coprinus, Coprinus comatus, and a few other species, were found to be more closely related to Agaricaceae. The former genus Coprinus was split between two families, and the name "Coprinaceae" became a synonym of Agaricaceae in its 21st-century phylogenetic redefinition. Note that in the 19th and early 20th centuries the family name Agaricaceae had far broader application, while in the late 20th century it had a narrower application. The family name Psathyrellaceae is based on the former Coprinaceae subfamily name Psathyrelloideae. The type genus Psathyrella consists of species that produce fruiting bodies which do not liquify via autodigestion. Psathyrella remained a polyphyletic genus until it was split into several genera including 3 new ones in 2015.Lacrymaria is another genus that does not autodigest its fruiting bodies. 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).
