Chamaemyces is a genus of fungi in the family Agaricaceae. It was circumscribed by mycologist Franklin Sumner Earle in 1906. [2]
Based on current taxonomy, the genus comprises six species : [3]
Secotioid fungi produce an intermediate fruiting body form that is between the mushroom-like hymenomycetes and the closed bag-shaped gasteromycetes, where an evolutionary process of gasteromycetation has started but not run to completion. Secotioid fungi may or may not have opening caps, but in any case they often lack the vertical geotropic orientation of the hymenophore needed to allow the spores to be dispersed by wind, and the basidiospores are not forcibly discharged or otherwise prevented from being dispersed —note—some mycologists do not consider a species to be secotioid unless it has lost ballistospory.
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).
Leucocoprinus is a genus of fungi in the family Agaricaceae. Its best-known member is the distinctive yellow mushroom Leucocoprinus birnbaumii, which is found in plant pots and greenhouses worldwide. The type species is Leucocoprinus cepistipes. The genus has a widespread distribution and contains over 80 recognised species, however many of these species are very scarcely recorded and little known with only a small number of Leucocoprinus species which are commonly observed. The majority of the species in this genus are exclusive to tropical environments however numerous species have become a common sight in plant pots and greenhouses resulting in them becoming well known worldwide.
Nidularia is a genus of nine species of fungi in the family Agaricaceae. Their fruit bodies resemble tiny egg-filled bird nests. The name comes from the Latin nidus meaning nest. The related genus Mycocalia was segregated from Nidularia in 1961 based on differences in the microscopic structure of the peridium.
Battarrea is a genus of mushroom-producing fungi. The genus used to be classified in the family Tulostomaceae until molecular phylogenetics revealed its affinity to the Agaricaceae. Species of Battarrea have a peridium that rests atop an elongated, hollow stipe with a surface that tends to become torn into fibrous scales. Inside the peridium, the gleba consists of spherical, warted spores, and a capillitium of simple or branched hyphal threads that have spiral or angular thickenings. The genus is named after Italian priest and naturalist Giovanni Antonio Battarra.
Arachnion is a genus of gasteroid fungi in the family Agaricaceae.
Bovistella is a genus of puffball fungi in the family Agaricaceae. The genus was circumscribed by mycologist Andrew Price Morgan in 1892.
Constricta is a genus of fungi in the family Agaricaceae. This is a monotypic genus, containing the single species Constricta africana. Not much is known about C. africana, other than its appearance.
Disciseda is a genus of gasteroid fungi in the family Agaricaceae. It is a widely distributed genus that is prevalent in arid zones. Disciseda was circumscribed by mycologist Vassiliĭ Matveievitch Czernajew in 1845.
Hiatulopsis is a genus of two species of fungi in the family Agaricaceae. The genus was circumscribed in 1967 by mycologists K. Grinling and Rolf Singer with H. amara as the type species. H. aureoflava was added to the genus by Singer in 1989.
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.
Metraria is a genus of two species of fungi in the family Agaricaceae.
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).
Ripartitella is a genus of fungi in the family Agaricaceae. The genus was circumscribed by Rolf Singer in Mycologia vol.39 on page 85 in 1947.
Secotium is a genus of fungi in the family Agaricaceae. The members of this genus are closely related to ordinary Agaricus mushrooms, but do not open out in the usual way; this has given rise to the term "secotioid" for such mushrooms in general. They are thought to form an evolutionary link between agarics and gasteroid fungi. Secotium is a widespread genus, with species that are predominantly found in warm and arid regions.
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.
