Lepiota is a genus of gilled mushrooms in the family Agaricaceae. All Lepiota species are ground-dwelling saprotrophs with a preference for rich, calcareous soils. Basidiocarps are agaricoid with whitish spores, typically with scaly caps and a ring on the stipe. Around 400 species of Lepiota are currently recognized worldwide. Many species are poisonous, some lethally so.
The Agaricaceae are a family of basidiomycete fungi and include the genus Agaricus, as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae.
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).
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).
Mycocalia is a genus of fungi in the family Agaricaceae. Their fruit bodies resemble tiny egg-filled birds' nests. Species are usually found growing on herbaceous stems and other plant debris. Thus genus was circumscribed in 1961 by mycologist J.T. Palmer with Mycocalia denudata as the type species.
Attamyces is a fungal genus in the family Agaricaceae. This is a monotypic genus, containing the single species Attamyces bromatificus. The fungus was found fruiting on the nest of the fungus-growing ants Atta insularis in Cuba. Both the species and genus were described by German mycologist Hanns Kreisel in 1972. The specific epithet bromatificus refers to bromatia, which are swollen tips on the hyphae that the ants use as food.
Barcheria is a fungal genus in the family Agaricaceae. This is a monotypic genus, containing the single sequestrate species Barcheria willisiana, found in western Australia.
Clarkeinda is a genus of fungi in the family Agaricaceae. According to the Dictionary of the Fungi, the widespread genus contains five species. Species in this genus, especially Clarkeinda trachodes, are only distributed in south Asia and southeast Asia.
Janauaria is a fungal genus in the family Agaricaceae. This is a monotypic genus, containing the single species Janauaria amazonica, found in Brazil and described as new to science in 1986 by mycologist Rolf Singer.
Lycogalopsis is a genus of puffball fungi in the family Agaricaceae. It was circumscribed by mycologist Eduard Fischer in 1886, with L. solmsii as the type species.
Lycoperdopsis is a fungal genus in the family Agaricaceae. A monotypic genus, it contains the single gasteroid species Lycoperdopsis arcyrioides, described as new to science in 1900.
Metrodia is a genus of fungi in the family Agaricaceae. It was circumscribed in 1971 by mycologist Jörg H. Raithelhuber, with M. collybioides as the type species. M. excissa was added to the genus in 1983.
Ripartitella is a genus of fungi in the family Agaricaceae. The genus was described by Rolf Singer in 1947.
Xerocoprinus is a fungal genus in the family Agaricaceae. This is a monotypic genus, containing the single species Xerocoprinus arenarius, originally named Coprinus arenarius by Narcisse Théophile Patouillard in 1896. Xerocoprinus was circumscribed by French mycologist René Maire in 1907.
Coniolepiota is a fungal genus in the family Agaricaceae. The genus is monotypic, containing only a single species, Coniolepiota spongodes. It was first described from Thailand, and later also reported from Bangladesh and China.
Eriocybe is a fungal genus in the family Agaricaceae. Circumscribed by mycologist Else Vellinga in 2011, it is a monotypic genus, containing the single species Eriocybe chionea, found in northern Thailand. The genus name is derived from the Ancient Greek words ἔριον, meaning "wool" and κύβη, "head". The specific epithet comes from the Latin translation of the Greek χιόνεος, meaning "snow white".
Clavogaster virescens is a species of secotioid or pouch-like fungus in the family Agaricaceae. It is endemic and indigenous to New Zealand, where it grows on rotting wood in native bush and mixed native and introduced forests. It has a stout yellowish stem, and a powder blue, purpleish or greenish blue cap that forms a pouch, often referred to as a peridium, enclosing reddish brown or orange chambered gleba. The species is sometimes knows as the "Spindle Pouch".
