Coprinopsis atramentaria, commonly known as the alcohol inky cap, common ink cap, tippler's bane, or inky cap, is a species of fungus. It is the second best-known ink cap after Coprinus comatus, its former congener. 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 is a widespread and common 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. It can be eaten,

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

Coprinopsis picacea, commonly known as the magpie mushroom, magpie fungus, or magpie inkcap, is a species of fungus in the family Psathyrellaceae.

Protostropharia semiglobata, commonly known as the hemispherical stropharia, the dung roundhead, or the halfglobe mushroom, is an agaric fungus of the family Strophariaceae. The mushrooms have hemispherical straw yellow to buff-tan caps measuring 1–4 cm (0.4–1.6 in), greyish gills that become dark brown in age, and a slender, smooth stem 3–12 cm (1.2–4.7 in) long with a fragile ring. A common and widespread species with a cosmopolitan distribution, the fungus produces mushrooms on the dung of various wild and domesticated ruminants.

Neolentinus lepideus is a basidiomycete mushroom of the genus Neolentinus, until recently also widely known as Lentinus lepideus. Common names for it include scaly sawgill, scaly lentinus and train wrecker.

Parasola plicatilis, commonly known as the pleated inkcap, is a small saprotrophic mushroom. The body resembles a cocktail umbrella. The plicate cap is up to 3.5 centimetres (1+1⁄2 in) wide. The species has no veil. Though nonpoisonous, the species is generally regarded as inedible and thin-fleshed. Two related species, P. hemerobia and P. leiocephala, have similar microscopic features but appear in different habitats and have unique spores. Other lookalikes include Leucocoprinus fragilissimus and members of Coprinopsis, Narcissea, and Tulosesus. P. plicatilis is a widely distributed species

Coprinopsis nivea, commonly known as the snowy inky cap or snowy inkcap, is a species of mushroom producing fungus in the family Psathyrellaceae.

Coprinopsis lagopus, commonly known as the hare's foot inkcap, harefoot mushroom, or rabbit's foot inky cap, is a species of fungus in the family Psathyrellaceae. It is commonly known as the harefoot mushroom due to the vague resemblance of the young fruit body to the paw of a white rabbit. 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.

Ampulloclitocybe clavipes, commonly known as the club-foot or club-footed clitocybe, is a species of gilled mushroom from Europe and North America. The grey-brown mushrooms have yellowish decurrent gills and a bulbous stalk, and are found in deciduous and conifer woodlands. While potentially edible, it resembles poisonous species and its consumption with alcohol can result in a disulfiram-like reaction.

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 (except for P. conopilea which was recently added to the genus). In the past these mushrooms were classified under Coprinus, but unlike that genus there is no veil and the caps do not break down into inky fluid, but curl up and wither as they age. Species in this genus are commonly known as umbrella inky caps.

Lichenomphalia umbellifera, also known as the lichen agaric or the green-pea mushroom lichen, is a species of basidiolichen in the family Hygrophoraceae. It forms a symbiotic relationship with unicellular algae in the genus Coccomyxa.

Lichenomphalia is both a basidiolichen and an agaric genus. Most of the species have inconspicuous lichenized thalli that consist of scattered, small, loose, nearly microscopic green balls or foliose small flakes containing single-celled green algae in the genus Coccomyxa, all interconnected by a loose network of hyphae. The agaric fruit bodies themselves are nonlichenized and resemble other types of omphalinoid mushrooms. These agarics lack clamp connections and do not form hymenial cystidia. The basidiospores are hyaline, smooth, thin-walled, and nonamyloid. Most of the species were

Coprinopsis cinerea is a species of mushroom in the family Psathyrellaceae. Commonly known as the gray shag, it is edible, but must be used promptly after collecting. Coprinopsis cinerea is an important model organism for studying fungal sex and mating types, mushroom development, and the evolution of multicellularity of fungi. The genome sequence was published in 2010. It is considered to be particularly suited organism to study meiosis, due to its synchronous meiotic development and prolonged prophase.

Coprinellus truncorum is a species of mushroom-forming fungus in the family Psathyrellaceae. Part of the cluster of mushrooms morphologically related to Coprinellus micaceus, this species can be distinguished from C. micaceus by a smooth, rather than pruinose (powdery) stipe, and by having more elliptical spores. Although not conclusively proven, this species may be conspecific with C. micaceus.

Hypsizygus ulmarius, also known as the elm oyster mushroom, and less commonly as the elm leech. It has often been confused with oyster mushrooms in the Pleurotus genus but can be differentiated easily as the gills are either not decurrent or not deeply decurrent. While not quite as common as true oyster mushrooms, they have a wide range globally in temperate forests. It is an edible species. The mushrooms and vegetative hyphae of this species have been studied in recent years for their potential benefits to human health, and mycoremediation.

Parasola auricoma or goldenhaired inkcap is a species of agaric fungus in the family Psathyrellaceae first described scientifically in 1886. 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)

Neolentinus is a genus of wood-decaying agarics with tough (leathery to woody) fruit bodies composed of dimitic tissue, serrated lamella edges, and nonamyloid white binucleate basidiospores among other features. It was segregated from Lentinus in the broad taxonomic sense, hence the derivation of the name. Biologically Neolentinus species produce a brown rot type of decay of wood, whereas Lentinus causes a white rot. Molecular phylogenetic analysis shows that the two genera are unrelated. Neolentinus is phylogenetically allied to other brown rot genera such as Gloeophyllum, Heliocybe, and

Ampulloclitocybe is a genus of three species of fungi with a widespread distribution.

Agroathelia rolfsii is a corticioid fungus in the order Amylocorticiales. It is a facultative plant pathogen and is the causal agent of "southern blight" disease in crops.

Phloeomana speirea, commonly known as the bark bonnet, is a species of fungus in the family Porotheleaceae. It is a bark-inhabiting agaric that produces fuscous-colored to whitish mycenoid to omphalinoid fruit bodies in temperate forests. The fungus was first described to science as Agaricus speireus by Elias Fries in 1815. Scott Redhead transferred it to the new genus Phloeomana in 2013, in which it is the type species.

Cyptotrama asprata (alternatively spelled aspratum), commonly known as the golden-scruffy collybia or spiny woodknight is a saprobic species of mushroom in the family Physalacriaceae. This fungus has had a varied taxonomical history, having been placed in fourteen genera before finally settling in Cyptotrama. It is characterized by the bright orange to yellow cap that in young specimens is covered with tufts of fibrils resembling small spikes. This species is differentiated from several other similar members of genus by variations in cap color, and spore size and shape. It is widely

Arrhenia spathulata is a mushroom-forming fungus in the family Hygrophoraceae. Found in Europe, it is widespread along the Atlantic coast.

Arrhenia epichysium is a species of agaric fungus in the family Hygrophoraceae. The fruit body has small brown to dark gray caps measuring 1–3 cm (1⁄2–1+1⁄4 in) in diameter. The cap color changes to light gray to tan when it is dry. The gills are narrow and thin, placed together closely, and decurrently attached to the stipe, which can be up to 5 cm (2 in) long. The flesh is grayish and watery. The spores are smooth and ellipsoid, measuring 6–7.5 μm. The spore print is white. Outside of its genus, it can resemble the slightly larger Pseudoclitocybe cyathiformis. It can be found on dead wood

Ossicaulis is a genus of mushroom-forming fungi in the family Lyophyllaceae.

Lichenomphalia hudsoniana is a species of basidiolichen in the family Hygrophoraceae. It is widely distributed in alpine and arctic regions of the world, where it grows on moist soil amongst moss.

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."
