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).
Cyptotrama asprata, commonly known as the golden-scruffy collybia or spiny woodknight is a saprobic species of mushroom in the family Physalacriaceae. Widely distributed in tropical regions of the world, it is characterized by the bright orange to yellow cap that in young specimens is covered with tufts of fibrils resembling small spikes. This fungus has had a varied taxonomical history, having been placed in fourteen genera before finally settling in Cyptotrama. This species is differentiated from several other similar members of genus Cyptotrama by variations in cap color, and spore size and shape.
Cyptotrama is a genus of mushrooms in the family Physalacriaceae.
Xanthoconium is a genus of bolete fungi in the family Boletaceae. It was circumscribed by mycologist Rolf Singer in 1944, who included Boletus affinis and what was then known as Gyroporus stramineus as the type species. These two species were part of the "strange group of species described by Murrill and Snell as white-spored Gyropori, and separated by the latter under the new generic name Leucogyroporus." C.B. Wolfe described three species from the United States in 1987: X. chattoogaense, Xanthoconium montaltoense, and X. montanum. As of February 2015, the nomenclatural database Index Fungorum list seven species in Xanthoconium.
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.
Physalacria is a genus of fungi in the family Physalacriaceae. The genus contains 30 species widely distributed in tropical regions of the Southern Hemisphere.
Rhizomarasmius is a genus of fungi in the family Physalacriaceae, containing about five species.
Hiatulopsis is a genus of two species of fungi in the family Agaricaceae. The genus was circumscribed in 1967 by mycologists K. Grinling and Rolf Singer with H. amara as the type species. H. aureoflava was added to the genus by Singer in 1989.
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.
Epicnaphus is a genus of mushroom-forming fungi in the family Marasmiaceae. The genus, circumscribed by mycologist Rolf Singer in 1960, contains two species found in South America. Fruitbodies of Epicnaphus species are similar in appearance to those in Marasmius section Sicci, but have a smooth hymenium and broom cells of the Rotalis-type. Singer initially included only the type species, E. phalaropus, which was originally collected from fallen branches in a Bolivian rainforest. The Argentinian species E. longispora was added to the genus by Jörg Raithelhuber in 1973.
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.
Cribbea is a genus of secotioid fungi in the family Physalacriaceae. The genus has a widespread distribution in southern temperate areas, and, according to a 2008 estimate, contains four species. A new species, Cribbea turbinispora, was reported from Australia in 2009, and in the same publication, C. lamellata was synonymized with C. gloriosa. The genus is named after mycologist Joan Cribb, in recognition of her contribution to fungal taxonomy.
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.
Pachylepyrium is a genus of fungi in the family Tubariaceae. The genus was circumscribed by Rolf Singer in 1958. The genus Pachylepyrium is widespread in northern temperate areas. Some species of Pachylepyrium have been moved to the genus Crassisporium.
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.
Cryptomarasmius is a genus of fungi in the family Physalacriaceae.
Cibaomyces is an agaric fungal genus found in China, Japan, France, and Germany in forests containing Fagaceae. It resembles Hymenopellis radicata because of its size, radiating stipe and glutinous cap. Unlike species in the genus Hymenopellis, Cibaomyces produces spiny basidiospores. DNA sequence data show it to be distinct from Dactylosporina, another spiny-spored genus in the Physalacriaceae.
