The following is a list of the species of the genus Coprinopsis in the family Psathyrellaceae. Coprinopsis was split out of the genus Coprinus based on molecular data. The species Coprinopsis cinerea is a model organism for mushroom-forming basidiomycota, and its genome has been sequenced completely.
Coprinus is a small genus of mushroom-forming fungi consisting of Coprinus comatus—the shaggy ink cap (British) or shaggy mane (American)—and several of its close relatives. Until 2001, Coprinus was a large genus consisting of all agaric species in which the lamellae autodigested to release their spores. The black ink-like liquid this creates gave these species their common name "ink cap" (British) or "inky cap" (American).
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.
Parasola is a genus of coprinoid mushrooms in the family Psathyrellaceae. These small frail fungi have translucent caps where the radiating gills look like the spokes of a parasol. In the past these mushrooms were classified under Coprinus, but unlike that genus there is no veil and the caps do not really turn to ink, but curl up and wither.
Arrhenia is a genus of fungi in the family Hygrophoraceae. Arrhenia also includes species formerly placed in the genera Leptoglossum and Phaeotellus and the lectotype species itself has an unusual growth form that would not normally be called agaricoid. All of the species grow in association with photosynthetic cryptogams such as mosses, including peat moss, and alga scums on decaying wood, and soil crusts consisting of mixes of such organisms. Typically the fruitbodies of Arrhenia species are grey to black or blackish brown, being pigmented by incrusting melanized pigments on the hyphae.
Tulosesus amphithallus is a species of mushroom producing fungus in the family Psathyrellaceae.
Tulosesus plagioporus is a species of mushroom producing fungus in the family Psathyrellaceae.
Tulosesus heterosetulosus is a species of mushroom producing fungus in the family Psathyrellaceae.
Tulosesus subpurpureus is a species of mushroom producing fungus in the family Psathyrellaceae.
Tubaria is a genus of fungi in the family Tubariaceae. The genus is widely distributed, especially in temperate regions. Tubaria was originally named as a subgenus of Agaricus by Worthington George Smith in 1870. Claude Casimir Gillet promoted it to generic status in 1876. The mushrooms produced by species in this genus are small- to medium-sized with caps ranging in color from pale pinkish-brown to reddish-brown, and often with remnants of the partial veil adhering to the margin. Mushrooms fruit on rotting wood, or, less frequently, in the soil. There are no species in the genus that are recommended for consumption.
Parasola auricoma is a species of agaric fungus in the family Psathyrellaceae. First described scientifically in 1886, the species is found in Europe, Japan, and North America. The mushroom was reported in February 2019 in Colombia, in the city of Bogota by the mycologist Juan Camilo Rodriguez Martinez. The small, umbrella-shaped fruit bodies (mushrooms) of the fungus grow in grass or woodchips and are short-lived, usually collapsing with age in a few hours. The caps are up to 6 cm (2.4 in) wide, initially elliptical before flattening out, and colored reddish-brown to greyish, depending on their age and hydration. They are pleated with radial grooves extending from the center to the edge of the cap. The slender, whitish stems are up to 12 cm (4.7 in) long and a few millimeters thick. Microscopically, P. auricoma is characterized by the presence of setae in its cap cuticle. This characteristic, in addition to the relatively large, ellipsoid spores can be used to distinguish it from other morphologically similar Parasola species.
Coprinopsis acuminata, commonly known as the humpback inkcap mushroom and earlier as Coprinus acuminatus, is a coprophilous fungus that grows on herbivore dung. It is heterothallic.
Coprinopsis mexicana is a species of fungus in the family Psathyrellaceae. Originally described in 1918 as Coprinus mexicanus by American mycologist William Alphonso Murrill, it was transferred to Coprinopsis in 2001.
Coprinopsis martinii is a species of mushroom producing fungus in the family Psathyrellaceae.
Coprinopsis nivea is a species of mushroom producing fungus in the family Psathyrellaceae. It is commonly known as the snowy inkcap.
