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.
Calvatia is a genus of puffball mushrooms that includes the giant puffball C. gigantea. It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the puffballs, Calvatia spp. are now placed in the family Agaricaceae of the order Agaricales.
Petter Adolf Karsten was a Finnish mycologist, the foremost expert on the fungi of Finland in his day, and known in consequence as the "father of Finnish mycology".
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.
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.
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.
Passerinula is a genus of fungi in the class Dothideomycetes. The relationship of this taxon to other taxa within the class is unknown.
Roumegueriella is a genus of fungi in the class Sordariomycetes. It consists of three species.
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.
Mycotodea is a genus of fungi in the Ascomycota division. It was later placed in the Leptosphaeriaceae family. The widespread genus contained 14 species, before most were transferred to Leptosphaerulina and Leptopeltis genera. It was left as a monotypic genus, with just Mycotodea litoreaKirschst. (1939).
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.
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.
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.
Smithiogaster is a fungal genus in the family Agaricaceae. It is a monotypic genus, containing the single gasteroid species Smithiogaster volvoagaricus. Smithiogaster was circumscribed by J.E.Wright in 1975.
Robert Kühner was a French mycologist most notable for reviewing many forms of agaric genera.
Dennisiomyces is a genus of fungi in the family Tricholomataceae. Described by mycologist Rolf Singer in 1955, the genus contains five species found in South America.
Rimbachia is a genus of fungi in the family Tricholomataceae. The genus contains about ten species with a widespread distribution in tropical regions.
Carlo Luigi Spegazzini, in Spanish Carlos Luis Spegazzini, was an Italian-born Argentinian botanist and mycologist.
