Russulaceae
The Russulaceae are a diverse family of fungi in the order Russulales, with roughly 1,900 known species and a worldwide distribution. They comprise the brittlegills and the milk-caps, well-known mushroom-forming fungi that include some edible species. These gilled mushrooms are characterised by the brittle flesh of their fruitbodies. In addition to these typical agaricoid forms, the family contains species with fruitbodies that are laterally striped ( pleurotoid), closed (secotioid or gasteroid), or crust-like (corticioid). Molecular phylogenetics has demonstrated close affinities between species with very different fruitbody types and has discovered new, distinct lineages. An important group of root-symbiotic ectomycorrhizal fungi in forests and shrublands around the world includes ''Lactifluus'', ''Multifurca'', ''Russula'', and ''Lactarius''. The crust-forming genera ''Boidinia'', ''Gloeopeniophorella'', and ''Pseudoxenasma'', all wood-decay fungi, have basal positions ...

Lactarius (fungus)
''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. Systematics and taxonomy The genus ''Lactarius'' was described by Christian Hendrik Persoon in 1797 with '' L. piperatus'' as the original type species. In 2011, '' L. torminosus'' was accepted as the new type of the genus after the splitting-off of ''Lactifluus'' as separate genus. The name "''Lactarius''" is derived from the Latin ''lac'', "milk". Placement within Russulaceae Molecular phylogenetics uncovered that, while macromorphologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russula
''Russula'' is a very large genus composed of around 750 worldwide species of ectomycorrhizal mushrooms. They are typically common, fairly large, and brightly colored – making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include usually brightly coloured caps, a white to dark yellow spore print, brittle, attached gill (mushroom), gills, an absence of latex, and absence of partial veil or universal veil, volva tissue on the stem. Microscopically, the genus is characterised by the amyloid ornamented spores and flesh (trama) composed of spherocysts. Members of the related genus ''Lactarius (fungus), Lactarius'' have similar characteristics but emit a milky latex when their gills are broken. The genus was described by Christian Hendrik Persoon in 1796. Taxonomy Christian Hendrik Persoon first circumscription (taxonomy), circumscribed the genus ''Russula'' in his 1796 work ''Observationes Mycologicae'', and c ...

Zelleromyces
''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. The genus was circumscribed in Mem. Torrey Bot. Club vol.21 (3) on page 18 in 1960. The genus name of ''Zelleromyces'' is in honour of Sanford Myron Zeller (1885–1948), who was an American mycologist. Phylogenetic analyses show that ''Zelleromyces'' species fall into the genus ''Lactarius''. Nevertheless, the genus name is still in use and has not been formally synonymised with ''Lactarius'' yet. Species As accepted by Species Fungorum ''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Mi ...; Former species; (all are Russulaceae fa ...

Arcangeliella
''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 ''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 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.

Cystangium
''Cystangium'' is a genus of fungi in the family Russulaceae. The genus contains 32 species that are distributed in Australia and South America. ''Cystangium'' was described by American mycologists Rolf Singer and Alexander H. Smith in 1960. The taxon is phylogenetically part of ''Russula'' and thus probably a synonym. However, it has not been formally synonymised yet and continues to be used by taxonomists.

Pseudoxenasma
''Pseudoxenasma'' is a fungal genus in the family Russulaceae, described in 1976. The genus is monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispec ... and contains the single species ''Pseudoxenasma verrucisporum'', found in Sweden. The original description reads: "Fruitbody resupinate, effused, thin, hymenium more or less ceraceous, generally smooth. Hyphal system monomitic with the individual hyphae indistinct. Always with sulphocystidia i.e. with positive reaction to sulphovanilline as in ''Gloeocystidiellum''. The cystidia are provided with globose apical appendices (schizopapilles according to Boidin and Lanquetin). Basidia clavate, in most cases pleurobasidiate, with four sterigmata. Spores verrucose, thickwalled, broadly ellipsoid to subglobose in side view and with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multifurca
''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. ''Multifurca'' is morphologically intermediate between ''Lactarius'' and ''Russula'': Fruitbodies have adnate to subdecurrent gills and are zonate; latex (as in ''Lactarius'' and ''Lactifluus'') is present only in ''M. furcata''; spore print 300px, Making a spore print of the mushroom ''Volvariella volvacea'' shown in composite: (photo lower half) mushroom cap laid on white and ...

Russula Emetica
''Russula emetica'', commonly known as the sickener, emetic russula, or vomiting russula, is a basidiomycete mushroom, and the type species of the genus ''Russula''. It has a red, convex to flat cap up to in diameter, with a cuticle that can be peeled off almost to the centre. The gills are white to pale cream, and closely spaced. A smooth white stem measures up to long and thick. First described in 1774, the mushroom has a wide distribution in the Northern Hemisphere, where it grows on the ground in damp woodlands in a mycorrhizal association with conifers, especially pine. The mushroom's common names refer to the gastrointestinal distress they cause when consumed raw. The flesh is extremely peppery, but this offensive taste, along with its toxicity, can be removed by parboiling or pickling. Although it used to be widely eaten in Russia and eastern European countries, it is generally not recommended for consumption. There are many similar ''Russula'' species that have a red ...

Gloeopeniophorella
''Gloeopeniophorella'' is a genus of crust-like, wood-decaying fungi in the family Russulaceae. It contains six known species. ''Gloeopeniophorella'' was first described by Brazilian mycologist Johannes Rick Johannes (João Evangelista) Rick (19 January 1869 – 1946) was an Austrian-born Brazilian priest and mycologist considered the "father of Brazilian mycology". He was the first to systematically document the fungal biodiversity, particularly the ... in 1934. Hjortstam & Ryvarden (2007) wrote on ''Gloeopeniophorella'': "The genus should be fairly easy to recognize with species having an almost smooth hymenophore, hyphae without clamp-connections, both metuloids and gloeocystidia, and spores that are both rugose and amyloid. We are of the opinion that the dextrinoid reaction of the metuloids in ''Dextrinocystidium'' is not an important character for generic separation."

Boidinia
''Boidinia'' is a genus of crust fungi in the family Russulaceae. The genus is widely distributed, and contains 10 species. ''Boidinia'' was described in 1982 with the type species ''Boidinia furfuracea'' (formerly placed in '' Gloeocystidiellum''). It is named in honor of French mycologist Jacques Boidin. N. Maekawa (1994) wrote: "The genus ''Boidinia'' is a satellite genus of ''Gloeocystidiellum'' and differs from the latter in forming loose texture in subiculum and globose, echinulate to verrucose basidiospores." ''Boidinia'' is probably not monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants.

Milk-cap
Milk-cap (also milk cap, milkcap, or milky) is a common name that refers to mushroom-forming fungi of the genera ''Lactarius'', ''Lactifluus'', and ''Multifurca'', all in the family Russulaceae. The common and eponymous feature of their fruitbodies is the latex ("milk") they exude when cut or bruised. Mushrooms with typical milk-cap characteristics are said to have a lactarioid habit. Some of them are edible. Historically, these species were all united in the genus ''Lactarius'', but molecular phylogenetic analysis has shown that they belong in fact to three distinct clades: * ''Lactarius'' holds most of the milk-caps known from the Northern hemisphere. * ''Lactifluus'' contains mainly tropical species, but also some well known northern milk-caps. * ''Multifurca'' contains only one species exuding milk, '' M. furcata'' from North and Central America. Some prominent species *''Lactarius deliciosus'' - "saffron milk-cap" or "red pine mushroom" *''Lactarius deterrimus'' - "false ...
