Flammulina is a genus of fungi in the family Physalacriaceae. The genus, widespread in temperate regions, has been estimated to contain 10 species.
Tricholomopsis is a genus of fungi closely related to the large genus Tricholoma. Its best known member and type species is Tricholomopsis rutilans. The name means appearing like Tricholoma. The genus has a widespread distribution, and contains about 30 species. Tricholomopsis was described in 1939 by American mycologist Rolf Singer.
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).
Austroboletus is a genus of fungi in the family Boletaceae. The widely distributed genus contains 28 species that form mycorrhizal relationships with plants.
Boletellus is a genus of fungi in the family Boletaceae. The genus has a widespread distribution, especially in subtropical regions, and contains about 50 species. The genus was first described by American mycologist William Alphonso Murrill in 1909. The genus name means "small Boletus".
Oudemansiella is a genus of fungi in the family Physalacriaceae. The genus contains about 15 species that are widely distributed in tropical and temperate regions. Yang and colleagues revised the genus in a 2009 publication, describing several new species and several varieties. They classified species in the genus into four sections based on the structure of the cap cuticle: Oudemansiella, Mucidula, Dactylosporina, and Radicatae.
Rhizomarasmius is a genus of fungi in the family Physalacriaceae, containing about five species.
Pseudohiatula is a genus of fungi in the family Physalacriaceae. It was originally described as a subgenus of Mycena by the mycologist Rolf Singer before he moved to its own genus two years later. It was formerly thought to belong in the family Tricholomataceae, but a molecular phylogenetics study found it to be more closely The genus Cyptotrama in the Physalacriaceae. Rolf Singer had previously hypothesized these two genera to be closely related based on morphological features in 1986. It contains five species that are widely distributed in tropical areas.
Descolea is a genus of fungi in the family Bolbitiaceae. Described by mycologist Rolf Singer in 1952, the widespread genus contains about 15 species. It was formerly placed in the family Cortinariaceae because of its limoniform basidiospores and its ectomycorrhizal lifestyle. A 2013 molecular phylogenetics study by Tóth et al. found it to be closely related to the genus Pholiotina The genus Pseudodescolea, erected for the single Descolea-like species Pseudodescolea lepiotiformis, was formerly considered distinct until a 1990 study found it to be a synonym of Descolea antarctica.
Palaeocephala is a genus of fungi. This is a monotypic genus, containing the single species Palaeocephala cymatelloides, described by Rolf Singer in 1962. According to the Dictionary of the Fungi, the genus is classified in either the Marasmiaceae or Physalacriaceae families; the taxonomical database MycoBank includes it in the Marasmiaceae.
Flammulina velutipes is a species of agaric in the family Physalacriaceae. In the UK, it has been given the recommended English name of velvet shank. The species occurs in Europe and North America. Until recently Flammulina velutipes was considered to be conspecific with the Asian Flammulina filiformis, cultivated for food as "enokitake" or "golden needle mushroom", but DNA sequencing has shown that the two are distinct.
Strobilurus is a genus of fungi in the family Physalacriaceae. The genus has a widespread distribution in temperate regions, and contains 10 species. Species of Strobilurus grow on pine cones.
Gymnopaxillus is a genus of fungi in the family Serpulaceae. According to the Dictionary of the Fungi, the family contains four species found in temperate South America and Australia. Gymnopaxillus was circumscribed by mycologist Egon Horak in 1966 with G. morchelliformis as the type species. G. crubensis, described from Argentina, was added in 1989, while the Australasian species G. nudus and G. vestitus were added to the genus in 2001.
Pseudohiatula cyatheae is a species of fungus in the family Physalacriaceae, and the type species of the genus Pseudohiatula. The species was first described by mycologist Rolf Singer in 1938.
Cryptomarasmius is a genus of fungi in the family Physalacriaceae.
Protoxerula is a fungal genus in the family Physalacriaceae. Described in 2010 by American mycologist Ron Petersen, the genus is monotypic, containing the sole species Protoxerula flavo-olivacea. This species was originally described as a Xerula in 2008 and transferred to Oudemansiella the following year before the new genus was circumscribed to accommodate it. P. flavo-olivacea is known from northeastern Australia, where it fruits singly to scattered in undisturbed rainforest, usually near plants from the genera Acacia, Agathis, and Corymbia. The variety kimberleyana, named for its type locality in the Kimberley region of Western Australia, has a greenish-cream cap colour, gills that become white and readily crumble when dry, long pseudorhiza with a hairy surface, ellipsoid basidiospores, thick-walled "hairs" (setae) on the cap surface, and a unique capitulate ("head-like") pleurocystidia.
