Pseudobaeospora is a genus of fungi in the family Tricholomataceae. [1] A 2008 estimate placed about 20 species in the widespread genus. [2]
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.
Collybia is a genus of mushrooms in the family Tricholomataceae. The genus has a widespread but rare distribution in northern temperate areas, and contains three species that grow on the decomposing remains of other mushrooms.
Pegleromyces is a genus of fungi in the family Tricholomataceae. It is a monotypic genus, containing the single species Pegleromyces collybioides, found in Brazil, and described as new to science by mycologist Rolf Singer in 1981.
Asproinocybe is a genus of fungi in the family Tricholomataceae. The genus contains five species found in tropical Africa.
Caulorhiza is a genus of fungi in the family Tricholomataceae. The genus, which contains three species found in the US, was circumscribed by Joanne Lennox in 1979.
Cellypha is a genus of fungi in the family Tricholomataceae. The widespread genus contains 10 species.
Clavomphalia is a genus of fungi in the family Tricholomataceae. It is a monotypic genus, containing only Clavomphalia yunnanensis, a Chinese species first described by German mycologist Egon Horak in 1987.
Delicatula is a genus of fungi in the family Tricholomataceae. It was first described by Swiss mycologist Victor Fayod in 1889. The genus contains two widely distributed species.
Dennisiomyces is a genus of fungi in the family Tricholomataceae. Described by mycologist Rolf Singer in 1955, the genus contains five species found in South America.
Leucocortinarius is a genus of fungus in the family Tricholomataceae. It is a monotypic genus, containing the single species Leucocortinarius bulbiger, found in Europe.
Mycenella is a genus of fungi in the family Tricholomataceae. The widespread genus contains 10 species, found mostly in temperate regions. Mycologist Rolf Singer circumscribed the genus in 1938.
Melanomphalia is a genus of fungi in the family Tricholomataceae. The genus is monotypic, containing the single species Melanomphalia nigrescens, found in Europe. The species was first described by M.P. Christensen in 1936.
Myxomphalia is a genus of fungi in the family Tricholomataceae. The genus has a widespread distribution in north temperate areas, and contains four species.
Omphaliaster is a genus of fungi in the family Tricholomataceae. The widespread genus contains seven species, predominantly in northern temperate regions.
Phaeomycena is a genus of fungi in the family Tricholomataceae. The genus contains five species found in Asia and Africa.
Physocystidium is a genus of fungi in the family Tricholomataceae. This is a monotypic genus, containing the single species Physocystidium cinnamomeum. This species is found in Trinidad, and was originally described as new to science in 1951 as Collybia cinnamomea by mycologist R.W.G. Dennis; Rolf Singer transferred it to the then newly created genus Physocystidium in 1962.
Pleurella is a genus of fungi in the family Tricholomataceae. This is a monotypic genus, containing the single species Pleurella ardesiaca, found in New Zealand.
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.
Nothoclavulina is a genus of fungus in the family Tricholomataceae. The genus is monotypic, containing the single species Nothoclavulina ditopa, described by American mycologist Rolf Singer in 1970. The species, found in Argentina, is an anamorphic version of the genus Arthrosporella. The generic name Nothoclavulina is Latin for "false Clavulina".
