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).
Crepidotus is a genus of fungi in the family Crepidotaceae. Species of Crepidotus all have small, convex to fan-shaped sessile caps and grow on wood or plant debris. The genus has been studied extensively, and monographs of the North American, European, and Neotropical species have been published.
Podaxis is a genus of secotioid fungi in the family Agaricaceae. Species, which have the appearance of a "stalked-puffball", have a worldwide distribution, and tend to be found growing solitary or scattered on sandy soils, especially in arid regions. Although close to 50 species have been described, it has been argued that many of them may represent extremes in the natural range of variations found in Podaxis pistillaris.
Allopsalliota is a fungal genus in the family Agaricaceae. A monotypic genus, it consists of the single species Allopsalliota geesterani, found in the Netherlands. The specific epithet honors Dutch mycologist Rudolph Arnold Maas Geesteranus. Allopsalliota was circumscribed in 1998 to contain what was then known as Agaricus geesterani, a species first described in 1986 by Cornelis Bas and Paul Heinemann.
Chlorolepiota is a genus of fungi in the family Agaricaceae. It is characterized by mushrooms with a macrolepiotoid habit, a pruinose yellow-greenish spore print, and the lack of clamp connections in the hyphae. The genus was circumscribed in 1979, with C. mahabaleshwarensis as the type and only species. C. indica was described in 2013, and C. brunneotincta in 2014. All species are found in India. The generic name Chlorolepiota is a portmanteau of Chlorophyllum and Macrolepiota, two closely related genera.
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.
Crucispora is a genus of fungi in the family Agaricaceae. The genus, described by mycologist Egon Horak in 1971, contains two species found in New Zealand and Asia.
Hymenagaricus is a genus of fungi in the family Agaricaceae. The widespread genus contains species found largely in tropical regions. Hymenagaricus was circumscribedby Belgian mycologist Paul Heinemann in 1981.
Leucoagaricus is a genus of mushroom-forming fungi in the family Agaricaceae. As of March 2023 there are over 200 accepted species of Leucoagaricus with ongoing research into the genus adding several more each year. Leucocoprinus is a similar genus and considered by some sources to be indistinct from Leucoagaricus based on genetic data that demonstrates they are monophyletic. Species are separated into these genera based on macroscopic features such as cap striations in Leucocoprinus or the more persistent basidiocarps (mushrooms) of Leucoagaricus as well as microscopic features such as the lack of a germ pore in Leucoagaricus species. As a result of the similarities and disagreement on taxonomy, many of the species within these genera have formerly been classified in the other and may still be known by previous classifications. For instance the species Leucoagaricus gongylophorus is cultivated by fungus-growing ants but was formerly known as Leucocoprinus gongylophorus whilst other species cultivated by the lesser attine ants are still classified as undescribed Leucocoprinus species.
Queletia is a genus of fungi in the family Agaricaceae. The genus was circumscribed by Elias Magnus Fries in 1872. Fruit bodies of Queletia species are sequestrate with a thin outer skin (peridium) and a harder inner skin that breaks into small pieces with age. The genus is named after French mycologist Lucien Quélet (1832–1899).
Smithiomyces is a genus of fungi in the family Agaricaceae. It was circumscribed by Rolf Singer in 1944. The type species, S. mexicanus, was formerly placed in Amanita, as well as the now obsolete genera Leucomyces and Venenarius. The genus was named to honor American mycologist Alexander H. Smith.
Xanthagaricus is a genus of fungi in the family Agaricaceae. The genus contains 23 species found in India, Sri Lanka, Bangladesh, Thailand, China and Africa. Originally described in 1984 by Belgian mycologist Paul Heinemann as Hymenagaricus subgen. Xanthagaricus, it was promoted to generic status in 1997.
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. The species has also been observed in Malaysia, Singapore, Cambodia, Indonesia, Taiwan, Philippines, and South Africa.
Paul Heinemann was a Belgian botanist and mycologist. Heinemann specialized in African mycology. In his long career, he published 435 names, including 2 families, 6 genera, 346 species, and 40 varieties. His collections of dried specimens, numbering about 7000, are preserved in the herbaria of the University Faculty of Agricultural Sciences in Gembloux and of the National Botanic Garden of Belgium, in Meise. The fungal genus Heinemannomyces was named in his honor, as were the species Agaricus heinemannianus, Marasmius heinemannianus, and Peyritschiella heinemanniana.
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".
Xanthagaricus flavosquamosus is a species of the fungal family Agaricaceae.This species is described from China.
