The Boletaceae are a family of mushroom-forming fungi, primarily characterised by small pores on the spore-bearing hymenial surface, instead of gills as are found in most agarics. Nearly as widely distributed as the agarics, the family is renowned for hosting some prime edible species highly sought after by mushroom hunters worldwide, such as the cep or king bolete . A number of rare or threatened species are also present in the family, that have become the focus of increasing conservation concerns. As a whole, the typical members of the family are commonly known as boletes.
The Omphalotaceae are a family of fungi in the order Agaricales. Basidiocarps are most frequently agarics, but occasionally corticioid or poroid.
The Agaricomycetes are a class of fungi in the division Basidiomycota. The taxon is roughly identical to that defined for the Homobasidiomycetes by Hibbett & Thorn, with the inclusion of Auriculariales and Sebacinales. It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. Within the subdivision Agaricomycotina, which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes, which are generally considered to be jelly fungi. However, a few former "jelly fungi", such as Auricularia, are classified in the Agaricomycetes. According to a 2008 estimate, Agaricomycetes include 17 orders, 100 families, 1147 genera, and about 21000 species. Modern molecular phylogenetic analyses have been since used to help define several new orders in the Agaricomycetes: Amylocorticiales, Jaapiales, Stereopsidales, and Lepidostromatales.
Rhodocybe is a genus of fungi in the family Entolomataceae. Basidiocarps are agaricoid producing pink basidiospores that are unevenly roughened or pustular under the microscope. Species are saprotrophic and mostly grow on the ground, occasionally on wood. The genus is distributed worldwide.
Rhizomarasmius is a genus of fungi in the family Physalacriaceae, containing about five species.
Callistosporium is a genus of fungi in the order Agaricales. Basidiocarps are agarics, either with a central stipe (stalk) or pleurotoid. The latter group were formerly referred to Pleurocollybia. Recent molecular research, based on cladistic analysis of DNA sequences, has shown that the genus is a natural, monophyletic grouping, though not all species have yet been sequenced. Species are saprotrophic, typically growing on wood, and the genus is found worldwide.
Catathelasma is a genus of fungi in the family Biannulariaceae. Basidiocarps are agaricoid, with a conspicuous veil, adnate to decurrent lamellae, and amyloid basidiospores. The genus is separated on DNA characteristics as well as morphology. Species are known from North America, Europe, and Asia and are ectomycorrhizal, forming an association with the living roots of trees.
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.
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.
Eichleriella is a genus of fungi in the order Auriculariales. Species produce effused or cupulate, waxy to leathery basidiocarps on wood, with a smooth to spiny surface. The genus contains some twelve species.
Catathelasma imperiale, also known as Catathelasma imperialis, and commonly known as the imperial mushroom, Hutsul mushroom, or korban, is a species of agaric in the family Biannulariaceae. Basidiocarps are stocky, with a double annulus (ring), and a tapering to rooting stipe (stem). The species is ectomycorrhizal with conifers and is found in continental Europe and Asia. Reports from North America are unconfirmed and may refer to Catathelasma evanescens or similar species. Fruit bodies are edible and collected for food in China and elsewhere. The species is widespread but uncommon and is assessed as globally "near threatened" on the IUCN Red List of Threatened Species.
Naiadolina is an agaric fungal genus that produces striking, yellowish fruit bodies on sedges in wetlands in eastern Canada. The lamellae are merulioid, forked and anastomosing. The type species was previously classified as a Marasmius in the Marasmiaceae, but phylogenetically, Naiadolina flavomerulina is in the Physalacriaceae sister to the genus Cryptomarasmius.
The genus Saproamanita contains about 24 species of agarics and is one of six genera in the family Amanitaceae, of which the similar Amanita is also a member. Saproamanita differs from Amanita in that its species are saprophytic, and not ectomycorrhizal.
Bonomyces is a genus of fungi in the family Biannulariaceae. Basidiocarps are agaricoid, similar to those of Clitocybe, but with a distinctly hard stipe (stem). The genus is separated on DNA characteristics as well as morphology. Species are known from Europe, North Africa, and northern China.
Bonomyces sinopicus is an agaricoid species of fungus in the family Biannulariaceae with a European districution. It has been given the recommended English name of spring funnel. The species was formerly placed in the genus Clitocybe, but has been separated on DNA characteristics.
The Biannulariaceae are a family of fungi in the order Agaricales. The family contains three genera. All species form agaricoid basidiocarps. The family was originally described to accommodate the single genus Catathelasma, but has been extended as a result of DNA research.
The Callistosporiaceae are a family of fungi in the order Agaricales. The family contains six genera. All species form agaricoid basidiocarps. The family is based on recent DNA research.
