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The Lycoperdales are a now outdated order of fungi. The order included some well-known types such as the giant puffball, the earthstars, and other tuberous fungi. They were defined as having epigeous basidiomes, a hymenium present, one to three layers in the peridium, powdery gleba, and brown spores.
The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft to very tough. Most members of this family have their hymenium in vertical pores on the underside of the caps, but some of them have gills or gill-like structures. Many species are brackets, but others have a definite stipe – for example, Polyporus badius.
Gautieria is a genus of hypogeal fungi in the family Gomphaceae. They form mycorrhizae with various tree species, mostly from the family Pinaceae. Species are present over much of the world's temperate and boreal forest habitats. It is well documented that species from this genera are an important part of the diet of the northern flying squirrel. Also, some Australian marsupials, especially the rat-kangaroos, feed extensively on these fungi. The fungi also benefit from this relationship: not only do the squirrels help to disperse the spores and propagate the species, studies suggest that passage through the digestive tract of a mammal promotes germination of spores.
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.
Nidula is a genus of fungi in the family Agaricaceae. Their fruit bodies resemble tiny egg-filled birds' nests, from which they derive their common name "bird's nest fungi". Originally described in 1902, the genus differs from the related genera Cyathus and Crucibulum by the absence of a cord that attaches the eggs to the inside of the fruit body. The life cycle of this genus allows it to reproduce both sexually, with meiosis, and asexually via spores. Species in this genus produce a number of bioactive compounds, including 4-(p-hydroxyphenyl)-2-butanone, a major component of raspberry flavor and insect attractor used in pesticides.
Battarrea phalloides is an inedible species of mushroom in the family Agaricaceae, and the type species of the genus Battarrea. Known in the vernacular as the scaley-stalked puffball, sandy stiltball, or desert stalked puffball, it has a woody, slender, and shaggy or scaly stem that is typically up to 40 centimeters (15.7 in) in length. Although its general appearance resembles an agaric with stem and gills, atop the stem is a spore sac, consisting of a peridium and a powdery internal gleba. In maturity, the spore sac ruptures to release the spores. Battarrea phalloides is found in dry, sandy locations throughout the world, and has been collected from Africa, Asia, Australia, Europe, North America, and South America. There is currently some disagreement in the literature as to whether the European B. stevensii is the same species as B. phalloides.
Arachnion is a genus of gasteroid fungi in the family Agaricaceae.
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.
Calbovista is a fungal genus containing the single species Calbovista subsculpta, commonly known as the sculptured puffball, sculptured giant puffball, and warted giant puffball. It is a common puffball of the Rocky Mountains and Pacific Coast ranges of western North America. The puffball is more or less round with a diameter of up to 15 cm (6 in), white becoming brownish in age, and covered with shallow pyramid-shaped plates or scales. It fruits singly or in groups along roads and in open woods at high elevations, from summer to autumn.
Montagnea is a genus of fungi in the family Agaricaceae. The genus has a widespread distribution in subtropical dry areas, and contains six species. Montagnea was circumscribed by Swedish mycologist Elias Magnus Fries in 1836.
Mycenastrum is a fungal genus in the family Agaricaceae. The genus is monotypic, containing one widely distributed species, Mycenastrum corium, known by various common names: the giant pasture puffball, leathery puffball, or tough puffball. The roughly spherical to turnip-shaped puffball-like fruit bodies grow to a diameter of 6–24 cm (2–9 in). Initially covered by a thick, felted, whitish layer, the puffballs develop a characteristic checkered skin (peridium) in age. When the internal spore mass, the gleba, is firm and white, the puffball is edible, although some individuals may suffer mild gastrointestinal symptoms after eating it. As the spores mature, the gleba turns first yellowish then purplish brown. Spores are released when the peridium eventually splits open into irregularly shaped sections. Microscopically, the gleba consists of spherical, dark brown spores with rounded bumps on their surfaces, and a capillitium—intricately branched fibers that form long thorn-like spines. The puffball grows on or in the ground in prairie or desert habitats. Although widely distributed, it is not commonly encountered. Mycenastrum corium is a threatened species in Europe.
Rugosospora is a genus of fungi in the family Agaricaceae. The genus contains two species: R. ochraceobadia, found in Africa, and R. pseudorubiginosa, found in Colombia and Mexico. These species have fruit bodies (mushrooms) with free gills, a white spore print, and a ring on the stipe. Rugosospora was circumscribed by Belgian mycologist Paul Heinemann in 1973.
Flaviporus is a genus of poroid fungi in the family Steccherinaceae.
Poronidulus is a fungal genus in the family Polyporaceae. It is a monotypic genus, and contains the single polypore species Poronidulus conchifer, found in North America. The genus was circumscribed by American mycologist William Alphonso Murrill in 1904. The generic name, which combines the Ancient Greek word πόρος ("pore") with the Latin word nidulus, refers to the superficial similarity of the cup-shaped Poronidulus fruit bodies with those of the genus Nidularia. A second species, Poronidulus bivalvis, found in Bogor, was placed in the genus by Franz Xaver Rudolf von Höhnel in 1914. The actual identity of this taxon, however, is uncertain.
Agaricus deserticola, commonly known as the gasteroid agaricus, is a species of fungus in the family Agaricaceae. Found only in southwestern and western North America, A. deserticola is adapted for growth in dry or semi-arid habitats. The fruit bodies are secotioid, meaning the spores are not forcibly discharged, and the cap does not fully expand. Unlike other Agaricus species, A. deserticola does not develop true gills, but rather a convoluted and networked system of spore-producing tissue called a gleba. When the partial veil breaks or pulls away from the stem or the cap splits radially, the blackish-brown gleba is exposed, which allows the spores to be dispersed.
Elias Judah Durand was an American mycologist, and botanist. He was one of the foremost American experts on the discomycetes.
Ramaria myceliosa is a species of coral fungus in the family Gomphaceae. Found in North America, it was originally described by Charles Horton Peck in 1904 with the name Clavaria myceliosa. The type was collected by botanist Edwin Bingham Copeland in the mountains near Stanford University in California. E.J.H. Corner transferred it to the genus Ramaria in 1950. Giachini and colleagues proposed that Ramaria myceliosa is the same species as the European Phaeoclavulina curta, but did not provide molecular evidence to support their suggested synonymy. In a recent (2014) publication on California fungi, the authors propose the transfer of Ramaria myceliosa to the genus Phaeoclavulina, but as of January 2016, this transfer has not been accepted by either MycoBank or Index Fungorum.
