Russulales genera

Russula is a very large genus composed of around 750 worldwide species of fungi. The genus was described by Christian Hendrik Persoon in 1796.

Lactarius is a genus of mushroom-producing, ectomycorrhizal fungi, containing several edible species. The species of the genus, commonly known as milk-caps, are characterized by the milky fluid ("latex") they exude when cut or damaged. Like the closely related genus Russula, their flesh has a distinctive brittle consistency. It is a large genus with over 500 known species, mainly distributed in the Northern hemisphere. Recently, the genus Lactifluus has been separated from Lactarius based on molecular phylogenetic evidence.

Albatrellus is a genus of 19 species of mushroom-producing fungi in the family Albatrellaceae. Species are common in northern temperate forests, producing medium to large fleshy fruit bodies of various colors.

Stereum is the type genus of the Stereaceae family of fungi, in the Russulales order. 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.

Auriscalpium is a genus of mushroom-forming fungi typifying the family Auriscalpiaceae.

Heterobasidion is a genus of basidiomycetes in the family of Bondarzewiaceae. Species in this genus include tree decay fungi that may be pathogenic and cause deterioration of tree health including mortality. Fungi in the genus produce shelf-like polyporous fruiting bodies that release spores from pores. Mating studies in the late twentieth century and genetic studies in the early twenty-first century have led to description of several new species and replacement of some of the original names. As a result, two former Heterobasidion species, H. annosum and H. insulare, are now recogniz

Amylostereum is the single genus in the fungal family Amylostereaceae. The genus currently comprises four saprotrophic and parasitic species, which live off living or dead wood. The Amylostereaceae cause white rot in the wood by disintegrating the tissue component lignin. They produce crust-like, partially wavy fruit bodies on the surface of infested trees, which are similar to those produced by Stereum species.

Peniophora is a genus of fungi which are plant pathogens. Members of the genus belong to the class Agaricomycetes, order Russulales, and family Peniophoraceae. The genus is widespread, and contains 62 species. The species of Peniophora are resupinate, or crust-like, and are described as corticioid. A number of its members are parasitised by other fungi. For example, Tremella mesenterica is a parasite to several species of Peniophora.

Lactifluus is one of three genera of mushroom-forming fungi containing species commonly named "milk-caps", the others being Lactarius and Multifurca. It has been separated from Lactarius based on molecular phylogenetic evidence but is very similar to that genus. There are roughly 150 known Lactifluus species, which have a mainly tropical distribution but are also found in the north temperate zone and Australasia. Some of them are edible mushrooms.

Bondarzewia is a widely distributed genus of fungi in the family Bondarzewiaceae. The genus was circumscribed by mycologist Rolf Singer in 1940.

Lentinellus is a genus of white rot, wood decay, lamellate agaric in the family Auriscalpiaceae, further characterized in part by rough-walled, amyloid spores produced on lamellae with jagged edges. Typically, thick-walled hyphae in the fruit body are in part amyloid, and frequently the taste of the mushrooms is acrid (burning, spicy). The widespread genus has been estimated to contain 15 species. Mycologists Ronald Petersen and Karen Hughes considered 24 species in their 2004 world monograph of the genus.

Laxitextum is a genus of fungi in the family Hericiaceae. The widespread genus contains three species. It was circumscribed by Paul Lewis Lentz in 1955. Species in the genus have fruit bodies that are effused (stretched out flat) to reflexed (with edges turned up) and a smooth hymenium. Molecular analysis shows that the genus groups in a clade with the genera Hericium and Dentipellis. ==Species== {| class="wikitable" |- ! Image !! Scientific name !!

Dentipellis is a genus of fungi in the family Hericiaceae. It was circumscribed by Dutch mycologist Marinus Anton Donk in 1962. Species in the genus have membranous fruit bodies that are either completely resupinate or effuso-reflexed (stretched out flat on the substrate but turned up at the edges). The hymenium (spore-bearing surface) bears "teeth".

Laurilia is a monotypic genus of crust fungi in the family Echinodontiaceae. The genus was described in 1959 by Czech mycologist Zdeněk Pouzar, with Laurilia sulcata (originally Stereum sulcatum) as the type and only species. Pouzar then transferred Laurilia taxodii from Stereum to Laurilia in 1968, but Liu et al. erected the new genus Lauriliella for the latter species in 2017 on the basis of ribosomal DNA molecular phylogeny. Liu et al. also found the Echinodontiaceae as traditionally circumscribed to be paraphyletic and placed Laurilia and Lauriliella instead in the Bondarzewiaceae, though

Echinodontium is a genus of fungi in the family Echinodontiaceae. The genus was published by American mycologist Job Bicknell Ellis in 1900, who described it thus: "Differs from Hydnum in the thick, woody pileus of Fomes and the teeth beset with spines, as in Mucronophorus and Hymenochaete". The type species, Echinodontium tinctorium, is commonly known as the "indian paint fungus" owing to its traditional use for bodypainting.

Multifurca is a rare genus of ectomycorrhizal fungi in the family Russulaceae. It was described in 2008, after molecular phylogenetic study had shown that it forms a monophyletic lineage within the family, sister to Lactarius. The genus contains six species known from the United States, Mexico, Costa Rica, India, China, Thailand, Australia, and New Caledonia, but so far has not been reported from Europe, Africa, or South America. Four of those species were formerly classified as Russula section Ochricompactae, and Multifurca furcata was originally described as a Lactarius species.

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.

Polyporoletus is a genus of fungi in the family Albatrellaceae. The genus was first described by mycologist Walter H. Snell in 1936 to accommodate an unusual terrestrial polypore with a stipe that had been found in the ground in pine-oak woods in Fentress County, Tennessee. He named this specimen Polyporoletus sublividus; the generic name refers to the possible relationship to both the boletes and the polypores. Although this species would be later transferred to the genus Scutiger, it is now considered to be Polyporoletus. Currently there are two other species in the genus, P. neotropicu
