List of Tricholomataceae genera

Last updated

The Tricholomataceae are a family of fungi in the order Agaricales. A 2008 estimate placed 78 genera and 1020 species in the family. [1] Subsequent molecular research, based on cladistic analysis of DNA sequences, has however found that this wide interpretation of the Tricholomataceae renders the family polyphyletic and is no longer tenable.

Contents

In 2014, Sánchez-García and colleagues proposed a revised classification of the Tricholomataceae with just seven genera: Leucopaxillus , Tricholoma , Dennisiomyces , Porpoloma , and the newly circumscribed genera Corneriella , Pogonoloma (now moved to the Pseudoclitocybaceae), and Pseudotricholoma . [2]

Of the genera formerly placed in the Tricholomataceae, Amparoina is considered a synonym of Mycena ; [3] Callistosporium (with Pleurocollybia as a synonym) and Macrocybe have been moved to the Callistosporiaceae [4] Catathelasma has been moved to the Biannulariaceae; [4] Phyllotopsis and Tricholomopsis to the Phyllotopsidaceae; [5] Leucopholiota and Squamanita to the Squamanitaceae; [6] Pseudoclitocybe , Musumecia , and Pogonoloma to the Pseudoclitocybaceae; [7] Cantharellopsis to the Rickenellaceae; [5] Arthromyces to the Lyophyllaceae; [8] and Hygroaster and Melanomphalia to the Hygrophoraceae; [9]

Following changes to the International Code of Nomenclature for algae, fungi, and plants, the practice of giving different names to teleomorph and anamorph forms of the same fungus has been discontinued. As a result two anamorphic genera referred to the Tricholomataceae become synonyms of their teleomorphs: Tilachlidiopsis becomes a synonym of Dendrocollybia and Nothoclavulina a synonym of Arthrosporella . [10]

Currently (2023) the following ten genera are accepted in the Tricholomataceae sensu stricto: Albomagister , Corneriella , Dennisiomyces , Dermoloma , Leucopaxillus , Porpoloma , Pseudobaeospora , Pseudoporpoloma , Pseudotricholoma , and Tricholoma . [11] An additional eleven genera are related, but not yet assigned to a family, and further genera await research. [11] All are listed below.

<i>Clitocybe</i> Genus of fungi

Clitocybe is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus.

<span class="mw-page-title-main">Marasmiaceae</span> Family of fungi

The Marasmiaceae are a family of fungi in the order Agaricales. Basidiocarps are most frequently agarics, but occasionally cyphelloid. According to a 2008 estimate, the family contained 54 genera and 1590 species, but molecular research, based on cladistic analysis of DNA sequences, has led to a more restricted family concept, so that the Marasmiaceae included just 13 genera, and some 1205 species. It was reduced further down in 2020, to 10 genera and about 700 species.

<span class="mw-page-title-main">Hygrophoraceae</span> Family of fungi

The Hygrophoraceae are a family of fungi in the order Agaricales. Originally conceived as containing white-spored, thick-gilled agarics, including Hygrophorus and Hygrocybe species, DNA evidence has extended the limits of the family, so it now contains not only agarics, but also basidiolichens and corticioid fungi. Species are thus diverse and are variously ectomycorrhizal, lichenized, associated with mosses, or saprotrophic. The family contains 34 genera and over 1000 species. None is of any great economic importance, though fruit bodies of some Hygrocybe and Hygrophorus species are considered edible and may be collected for sale in local markets.

<i>Camarophyllopsis</i> Genus of fungi

Camarophyllopsis is a genus of agarics in the family Clavariaceae. Basidiocarps are dull-coloured and have dry caps, rather distant, decurrent lamellae, white spores, and smooth, ringless stems. In Europe species are characteristic of old, unimproved grasslands which are a declining habitat, making them of conservation concern.

<span class="mw-page-title-main">Tricholomataceae</span> Family of fungi

The Tricholomataceae are a large family of fungi within the order Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae.

<i>Melanoleuca</i> Genus of fungi

Melanoleuca is a poorly known genus of saprotrophic mushrooms traditionally classified in the family Tricholomataceae. Most are small to medium sized, white, brown, ocher or gray with a cylindrical to subcylindrical stipe and white to pale yellowish gills. The basidiospores are ellipsoid and ornamented with amyloid warts. Melanoleuca is considered a difficult group to study due to their macroscopic similarities among species and the need of a thorough microscopic analysis to separate species. DNA studies have determined that this genus is closely related to Amanita and Pluteus and that it does not belong to the family Tricholomataceae.

<span class="mw-page-title-main">Physalacriaceae</span> Family of fungi

The Physalacriaceae are a family of fungi in the order Agaricales. Species in the family have a widespread distribution, ranging from the Arctic, (Rhizomarasmius), to the tropics, e.g. Gloiocephala, and from marine sites (Mycaureola) and fresh waters (Gloiocephala) to semiarid forests (Xerula).

Arthrosporella is a fungal genus in the family Tricholomataceae. It is a monotypic genus, containing the single species Arthrosporella ditopa, found in South America. The genus was described by mycologist Rolf Singer in 1970.

Haasiella is a fungal genus in the family Hygrophoraceae. It is a monotypic genus that contains only the species Haasiella splendidissima. Haasiella venustissima, formerly considered to be a distinct species based on its one and two-spored basidia, was found by a DNA study to be synonymous with H. splendidissima. H. splendidissima is only known from Europe and is saprotrophic on wood. Haasiella was described as a new genus in 1966 by Czech mycologists František Kotlaba and Zdeněk Pouzar. It is most closely related to the genus Hygrophorus.

<i>Infundibulicybe</i> Genus of fungi

Infundibulicybe is a genus of fungi that is robustly placed incertae sedis as sister group to the Tricholomatoid clade. It has previously been part of the family of Tricholomataceae, but recent molecular phylogeny has shown it to take an isolated position within the Agaricales.

Pleurocollybia is a genus of fungi in the family Callistosporiaceae. Basidiocarps are pleurotoid and grow on wood. DNA research has shown that the type species, P. praemultifolia belongs in the genus Callistosporium, making Pleurocollybia a synonym. Not all species have been investigated, however, and it is not clear that every Pleurocollybia species belongs in Callistosporium. Pleurocollybia cibaria has, for example, been transferred to the genus Gerhardtia.

<i>Pseudoomphalina</i> Genus of fungi

Pseudoomphalina is a genus of fungi in the placed in the family Tricholomataceae for convenience. The genus contains six species that are widespread in northern temperate areas. Pseudoomphalina was circumscribed by Rolf Singer in 1956. Pseudoomphalina was found to be paraphyletic to Neohygrophorus in a molecular phylogenetics study and since Pseudoomphalina is an older name, Neohygrophyorus was synonymized with it. The type species of Neohygrophorus was Neohygrophorus angelesianus, now Pseudoomphalina angelesiana. In earlier classifications based on anatomy prior to DNA sequence-based classifications, its unusual combination of features led taxonomists to independently create two subgenera in two genera: Hygrophorus subg. Pseudohygrophorus and Clitocybe subg. Mutabiles; the latter based on Neohygrophorus angelesianus but described under a new species name which is now placed in synonymy, Clitocybe mutabilis. All species of Pseudoomphalina are united by the presence of clamp-connections in their hyphae, an interwoven gill trama and amyloid spores. Pseudoomphalina angelesiana possesses grey-violaceous pigments that turn red in alkali solutions and lacks filiform, hyphal sterile elements in its hymenium and stipitipellis. These were features used to distinguish it from Pseudoomphalina as a genus, but Pseudoomphalina umbrinopurpurascens possesses these same pigments and the filiform elements of Pseudoomphalina. Molecular phylogenetics studies have also found some former species of Pseudoomphalina to belong in other genera. Pseudoomphalina pachyphylla was moved to its own genus, Pseudolaccaria, and Pseudoomphalina clusiliformis was synonymized with it. Pseudoomphalina flavoaurantia and Pseudoomphalina lignicola were found to belong in Clitocybula. Phylogenetically, Pseudoomphalina is in a tricholomatoid clade but not in the Tricholomataceae.

<i>Clitocybula</i> Genus of fungi

Clitocybula is a genus of mushroom-forming fungi in the family Porotheleaceae but was originally classified within Marasmiaceae. The genus was circumscribed by Georges Métrod in 1952. Species in the genus are commonly known as "coincaps".

<i>Albomagister</i> Genus of fungi

Albomagister is a genus of fungi in the family Tricholomataceae. The genus contains just one named species known from Tennessee and North Carolina, however two other undescribed species have been sequenced. Albomagister was described by mycologists Marisol Sánchez-García, Joshua Birkebak & P. Brandon Matheny in 2014 with Albomagister subaustralis as the type species.

<i>Singerocybe</i> Genus of fungi

Singerocybe is a genus of fungi that contains six species. Singerocybe was circumscribed by the Finnish mycologist Harri Harmaja in 1988 with Singerocybe viscida as the type species.

Egon Horak is an Austrian mycologist who has described more than 1000 species of fungi, including many from the Southern Hemisphere, particularly New Zealand and South America. He was an executive editor of the scientific journal Sydowia from 1975 to 1989, and a member of the editorial board afterwards.

<i>Paralepista</i> Genus of fungi

Paralepista is a genus of mushrooms in family Tricholomataceae. Until 2012, its member species were generally assigned either to Lepista or to Clitocybe.
