Austroomphaliaster is a fungal genus in the family Tricholomataceae. It is a monotypic genus, containing the single species Austroomphaliaster nahuelbutensis, also known as the Big Puma Mushroom, Austroomphaliaster nahuelbutensis was found in temperate South America. [2] This species lived on Patagonian Oak Trees and Dombey’s Beech Tree. [3] This species hasn’t been seen in 35 years and is part of Re:wild’s Search For Lost Species Initiative. In May 2023, specimens have been found which may be Austroomphaliaster nahuelbutensis, but DNA analysis is still needed to confirm the identity. [3]
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.
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.
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.
The Mycenaceae are a family of fungi in the order Agaricales. According to the Dictionary of the Fungi, the family contains 10 genera and 705 species. This is one of several families that were separated from the Tricholomataceae as a result of phylogenetic analyses. Taxa in the Mycenaceae are saprobic, have a cosmopolitan distribution, and are found in almost all ecological zones. The family was circumscribed by Caspar van Overeem in 1926.
Rhodotus is a genus in the fungus family Physalacriaceae. There are two species in the genus with the best known, Rhodotus palmatus, called the netted rhodotus, the rosy veincap, or the wrinkled peach. This uncommon species has a circumboreal distribution, and has been collected in eastern North America, northern Africa, Europe, and Asia; declining populations in Europe have led to its appearance in over half of the European fungal Red Lists of threatened species. Typically found growing on the stumps and logs of rotting hardwoods, mature specimens may usually be identified by the pinkish color and the distinctive ridged and veined surface of their rubbery caps; variations in the color and quantity of light received during development lead to variations in the size, shape, and cap color of fruit bodies.
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.
Callistodermatium is a fungal genus in the family Tricholomataceae. It is a monotypic genus, and contains the single species Callistodermatium violascens. The holotype was found in Brazil, and described by mycologist Rolf Singer in 1981.
Mycoalvimia is a genus of fungus in the family Tricholomataceae. It is a monotypic genus, and contains the single species Mycoalvimia theobromicola, found in Brazil.
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.
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.
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.
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.
Omphaliaster is a genus of fungi in the family Tricholomataceae. The widespread genus contains seven species, predominantly in northern temperate regions.
Pseudobaeospora is a genus of fungi in the family Tricholomataceae. A 2008 estimate placed about 20 species in the widespread genus.
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.
Rimbachia is a genus of fungi in the family Tricholomataceae. The genus contains about ten species with a widespread distribution in tropical regions.
Leucopholiota decorosa is a species of fungus in the mushroom family Tricholomataceae. Commonly known as the decorated pholiota, it is distinguished by its fruit body which is covered with pointed brown, curved scales on the cap and stem, and by its white gills. Found in the eastern United States, France, and Pakistan, it is saprobic, growing on the decaying wood of hardwood trees. L. decorosa was first described by American mycologist Charles Horton Peck as Agaricus decorosus in 1873, and the species has been transferred to several genera in its history, including Tricholoma, Tricholomopsis, Armillaria, and Floccularia. Three American mycologists considered the species unique enough to warrant its own genus, and transferred it into the new genus Leucopholiota in a 1996 publication. Lookalike species with similar colors and scaly fruit bodies include Pholiota squarrosoides, Phaeomarasmius erinaceellus, and Leucopholiota lignicola. L. decorosa is considered an edible mushroom.
Pseudotricholoma is a genus of fungi in the family Tricholomataceae. The genus contains three species known from North America. Europe, and the Azores. Basidiocarps resemble those of the genus Tricholoma, with a dry fibrillose pileus and white to brown lamellae that have adnate to emarginate attachment and stain reddish when damaged, eventually turning black. Microscopically, the basidiospores are smooth, ellipsoid to ellipsoid-oblong, thin-walled and amyloid. Cheilocystidia are rare to absent and pleurocystidia are absent. The pileipellis is a cutis and clamp connections are present. Species in Pseudotricholoma are found on soil in grasslands and woods. They are probably biotrophic, and may be ectomycorrhizal.
