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).
Coprinus comatus, commonly known as the shaggy ink cap, lawyer's wig, or shaggy mane, is a common fungus often seen growing on lawns, along gravel roads and waste areas. The young fruit bodies first appear as white cylinders emerging from the ground, then the bell-shaped caps open out. The caps are white, and covered with scales—this is the origin of the common names of the fungus. The gills beneath the cap are white, then pink, then turn black and deliquesce ('melt') into a black liquid filled with spores. This mushroom is unusual because it will turn black and dissolve itself in a matter of hours after being picked or depositing spores.
Coprinopsis is a genus of mushrooms 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 recently been sequenced completely.
Coprinopsis atramentaria, commonly known as the common ink cap, tippler's bane, or inky cap, is an edible mushroom found in Europe and North America. Previously known as Coprinus atramentarius, it is the second best known ink cap and previous member of the genus Coprinus after C. comatus. It is a widespread and common fungus found throughout the northern hemisphere. Clumps of mushrooms arise after rain from spring to autumn, commonly in urban and disturbed habitats such as vacant lots and lawns, as well as grassy areas. The grey-brown cap is initially bell-shaped before opening, after which it flattens and disintegrates. The flesh is thin and the taste mild. It can be eaten, but due to the presence of coprine within the mushroom, it is poisonous when consumed with alcohol, as it heightens the body's sensitivity to ethanol in a similar manner to the anti-alcoholism drug disulfiram.
Coprinopsis lagopus is a species of fungus in the family Psathyrellaceae. Until 2001, the species was known as Coprinus lagopus; advances in the understanding of phylogenetic relationships between the various coprinoid species led to a major reorganization of that genus. It is a delicate and short-lived fungus, the fruit bodies lasting only a few hours before dissolving into a black ink – a process called deliquescence. The vague resemblance of the young fruit body to the paw of a white rabbit has earned this species the common name harefoot mushroom.
Tulosesus angulatus is a species of mushroom producing fungus in the family Psathyrellaceae.
Coprinellus ellisii is a species of mushroom in the family Psathyrellaceae. Found in Europe, it was first described as Coprinus ellisii by Peter D. Orton in 1960, and later transferred to the genus Coprinellus in 2001. The specific epithet ellisii honours E.A. Ellis, who, according to Orton, was "the Norfolk naturalist and mycologist who collected this and who brought me many puzzling and apparently undescribed agarics."
Coprinellus curtus is a species of mushroom in the family Psathyrellaceae. It was first described as Coprinus curtus by Károly Kalchbrenner in 1876 before being transferred to the genus Coprinellus in 2001.
Tulosesus callinus is a species of mushroom producing fungus in the family Psathyrellaceae.
Tulosesus bisporus is a species of mushroom producing fungus in the family Psathyrellaceae.
Tulosesus pellucidus is a species of mushroom producing fungus in the family Psathyrellaceae.
Tulosesus marculentus is a species of mushroom producing fungus in the family Psathyrellaceae.
Tulosesus heterosetulosus is a species of mushroom producing fungus in the family Psathyrellaceae.
Coprinellus verrucispermus is a species of fungus in the family Psathyrellaceae. The fungus has been identified in a study of soils from the northern-central region of New South Wales, Australia. Formerly in the genus Coprinus, it was given its current name in 2001.
Tulosesus sassii is a species of mushroom producing fungus in the family Psathyrellaceae.
Coprinopsis variegata, commonly known as the scaly ink cap or the feltscale inky cap, is a species of fungus in the family Psathyrellaceae. Distributed in eastern North America, it has a medium-sized, bell-shaped to flattened cap up to 7.5 cm (3.0 in) in diameter, with felt-like, patchy scales. The gills, initially white, turn black in maturity and eventually dissolve into a black "ink". Fruit bodies grow in clusters or groups on leaf litter or rotted hardwood, although the wood may be buried, giving the appearance of growing in the soil. The fungus is found in the United States, in areas east of the Great Plains. Coprinus ebulbosus and Coprinus quadrifidus are names assigned by Charles Horton Peck to what he believed were species distinct from C. variegata; they were later shown to represent the same species, and are now synonyms. The mushroom is not recommended for consumption, and has been shown to cause allergic reactions in susceptible individuals.
Coprinopsis radiata, formerly known as Coprinus radiatus, and commonly known as the miniature woolly inky cap, is a coprophilous fungus that grows on herbivore dung. It is heterothallic.
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 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.
