Stereum is the type genus of the Stereaceae family of fungi, in the Russulales order. Until recently, the genus was classified in the Corticiaceae family, of the Corticiales order. However, it was given its own family as a result of the split-up of the Corticiales. Common names for species of this genus include leaf fungus, wax fungus, and shelf fungus. Fungi having a shape similar to a Stereum are said to have a stereoid shape. Stereum contains 27 species that have a widespread distribution.
The Pyronemataceae are a family of fungi in the order Pezizales. It is the largest family of the Pezizales, encompassing 75 genera and approximately 500 species. Phylogenetic analyses does not support the prior classifications of this family, and suggest that the family is not monophyletic as it is currently circumscribed.
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.
Lentinus is a genus of fungi in the family Polyporaceae. The genus is widely distributed, with many species found in subtropical regions.
Phlebia is a genus of mostly crust fungi in the family Meruliaceae. The genus has a widespread distribution. Phlebia species cause white rot.
Gigasperma is an inactive genus of fungi in the order Agaricales with a single species. It was treated either as the only genus in the monotypic family Gigaspermataceae, or part of the wider Cortinariaceae. Gigasperma was circumscribed by Austrian mycologist Egon Horak in 1971.
Pisolithus is a genus of fungi within the family Sclerodermataceae.
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.
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.
Descolea is a genus of fungi in the family Bolbitiaceae. Described by mycologist Rolf Singer in 1952, the widespread genus contains about 15 species. It was formerly placed in the family Cortinariaceae because of its limoniform basidiospores and its ectomycorrhizal lifestyle. A 2013 molecular phylogenetics study by Tóth et al. found it to be closely related to the genus Pholiotina The genus Pseudodescolea, erected for the single Descolea-like species Pseudodescolea lepiotiformis, was formerly considered distinct until a 1990 study found it to be a synonym of Descolea antarctica.
Lenzites is a widespread genus of wood-decay fungi in the family Polyporaceae. It was circumscribed by Elias Magnus Fries in 1835. The generic name honours German naturalist Harald Othmar Lenz (1798–1870).
Tyromyces is a genus of poroid fungi in the family Polyporaceae. It was circumscribed by mycologist Petter Karsten in 1881. The type species is the widely distributed Tyromyces chioneus, commonly known as the white cheese polypore. The phylogenetic position of Tyromyces within the Polyporales is uncertain, but it appears that it does not belong to the "core polyporoid clade". Tyromyces is polyphyletic as it is currently circumscribed, and has been described as "a dumping place for monomitic white-rot species with thin-walled spores."
Zelleromyces is a genus of fungi in the family Russulaceae. It was first described by mycologists Rolf Singer and Alexander H. Smith in 1960 to contain hypogeous (underground) fungi with gasteroid fruit bodies that "bleed" latex when they are cut.
Hysterangium is a genus of truffle-like fungi in the family Hysterangiaceae. The genus is widespread, especially in temperate regions, and contains more than 60 species. Hysterangium was circumscribed by Italian mycologist Carlo Vittadini in 1831.
Arcangeliella is a genus of gasteroid fungi in the family Russulaceae. Taxonomic and phylogenetic research has shown that it is very likely a synonym of Lactarius. The type species Arcangeliella borziana was moved to Lactarius in 2003. However, the genus name is still in use for several species for which new combinations have not yet been proposed.
Stephanospora is a genus of truffle-like gasteroid fungi in the order Agaricales. In 2014, nine new Australasian species were described from collections previously thought to represent S. flava.
