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 25 genera and over 600 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.
Cantharellopsis is a tan- to whitish-colored bryophilous monotypic genus in the Agaricales. The fruit bodies of the single species Cantharellus prescotii has a form intermediate between an Omphalina and a chanterelle (Cantharellus) because of its forked, fold-like gills. It inhabits moss on calcareous soils in temperate regions of Europe. Phylogenetically related agarics are in the genera Contumyces, Gyroflexus, Loreleia, Rickenella and Blasiphalia, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and the clavarioid genus, Alloclavaria.
Rhodotus is a genus in the fungus family Physalacriaceae. It is a monotypic genus and consists of the single mushroom species Rhodotus palmatus, known in the vernacular as 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 Tricholomataceae family. The genus has a widespread but rare distribution in north temperate areas, and contains three species that grow on the decomposing remains of other mushrooms.
Leucopholiota is a genus of fungi in the Tricholomataceae family of mushrooms. It consists of the species Leucopholiota decorosa and Leucopholiota lignicola.
Hygrophoropsis is a genus of gilled fungi in the family Hygrophoropsidaceae. It was circumscribed in 1888 to contain the type species, H. aurantiaca, a widespread fungus that, based on its appearance, has been affiliated with Cantharellus, Clitocybe, and Paxillus. Modern molecular phylogenetic analysis shows that the genus belongs to the suborder Coniophorineae of the order Boletales.
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.
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.
Austroomphaliaster is a fungal genus in the family Tricholomataceae. It is a monotypic genus, containing the single species Austroomphaliaster nahuelbutensis, found in temperate South America.
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.
Porpoloma is a genus of fungi in the family Tricholomataceae. The genus contains about 12 species found predominantly in South America. Porpoloma was described by mycologist Rolf Singer in 1952 with P. sejunctum as the type species.
Leucopholiota decorosa is a species of fungus in the Tricholomataceae family of mushrooms. 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.
Archaeomarasmius is an extinct genus of gilled fungus in the Agaricales family Tricholomataceae, containing the single species Archaeomarasmius leggetti. It is known from two fruit bodies recovered from amber, one consisting of a complete cap with a broken stem, the other consisting of a fragment of a cap. The cap has a diameter ranging from 3.2 to 6 mm, while the stem is 0.5 mm (0.02 in) thick. Spores were also recovered from the amber, and are broadly ellipsoid to egg-shaped, measuring roughly 7.3 by 4.7 μm. The species, which resembles the extant genera Marasmius and Marasmiellus, is inferred to have been saprobic on plant litter or other forest debris.
Aureofungus is an extinct monotypic genus of gilled fungus in the order Agaricales. At present it contains the single species Aureofungus yaniguaensis.
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.
Corneriella is a genus of fungi in the family Tricholomataceae. The genus contains two species known from the United States and Thailand, and at least four others have been detected by DNA sequencing. Corneriella was described the mycologist Marisol Sánchez-García in 2014 with Corneriella bambusarum as the type species.
Pseudotricholoma is a genus of fungi in the family Tricholomataceae. The genus contains two species known from the Canada, the United States and Europe. Pseudotricholoma was described the mycologists Marisol Sánchez-García and P. Brandon Matheny in 2014 with Pseudotricholoma umbrosum as the type species.
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.
