The Agaricaceae are a family of basidiomycete fungi and include the genus Agaricus, as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae.
Stereum is the type genus of the Stereaceae family of fungi, in the Russulales order. Until recently, the genus was classified in the Corticiaceae family, of the Corticiales order. However, it was given its own family as a result of the split-up of the Corticiales. Common names for species of this genus include leaf fungus, wax fungus, and shelf fungus. Fungi having a shape similar to a Stereum are said to have a stereoid shape. Stereum contains 27 species that have a widespread distribution.
An agaric is a type of fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. In the UK, agarics are called "mushrooms" or "toadstools". In North America they are typically called "gilled mushrooms". "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body.
Weraroa was a genus of mushrooms from the families Hymenogastraceae and Strophariaceae. The genus was initially described by mycologist Rolf Singer in 1958 to accommodate the single species Secotium novae-zelandiae reported by Gordon Herriott Cunningham in 1924. It was thought that the genus represented an intermediary evolutionary stage between a hypogeous (underground) ancestor and the related epigeous genus Stropharia. Advances in phylogenetics and taxonomic changes since 1958 found it contained unrelated species from multiple genera. It is now considered a synonym of the genus Psilocybe.
Psilocybe weraroa, formerly Weraroa novae-zelandiae, is a secotioid fungus in the family Hymenogastraceae. It is endemic to New Zealand, where it grows in native forests from rotting wood and woody debris. Despite its pouch-like form this species is closely related to Psilocybe cyanescens and Psilocybe subaeruginosa. As a bluing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin. It has been cultivated commercially by Rua Bioscience with a view to researching potential medical applications, bringing together its traditional uses in Rongoā Māori with the recent interest in Western medicine into the medical applications of psilocin and psilocybin.
Banksiamyces is a genus of fungi in the order Helotiales, with a tentative placement in the family Helotiaceae. The genus contains four species, which grow on the seed follicles of the dead infructescences or "cones" of various species of Banksia, a genus in the plant family Proteaceae endemic to Australia. Fruit bodies of the fungus appear as small, shallow dark cups on the follicles of the Banksia fruit. The edges of dry fruit bodies fold inwards, appearing like narrow slits. The first specimens of Banksiamyces, known then as Tympanis toomansis, were described in 1887. Specimens continued to be collected occasionally for almost 100 years before becoming examined more critically in the early 1980s, leading to the creation of a new genus to contain what was determined to be three distinct species, B. katerinae, B. macrocarpus, and B. toomansis. A fourth species, B. maccannii, was added in 1984.
Phlebopus is a genus of fungi in the family Boletinellaceae. The genus has a widespread distribution in subtropical and pantropical regions, and contains 12 species. The species are saprobic, with some possibly able to form mycorrhizae with exotic trees in certain conditions. It contains the gigantic Phlebopus marginatus, the cap of which can reach 1 m (3.3 ft) in diameter.
Gymnogaster is a genus of fungi in the family Boletaceae. It is a monotypic genus, containing the single secotioid species Gymnogaster boletoides, found in Australia. The fungus produces bright yellow fruit bodies with a light brown internal gleba, and the fruit bodies turn blue then dark brown after bruising or handling.
Leucoagaricus is a genus of mushroom-forming fungi in the family Agaricaceae. As of March 2023 there are over 200 accepted species of Leucoagaricus with ongoing research into the genus adding several more each year. Leucocoprinus is a similar genus and considered by some sources to be indistinct from Leucoagaricus based on genetic data that demonstrates they are monophyletic. Species are separated into these genera based on macroscopic features such as cap striations in Leucocoprinus or the more persistent basidiocarps (mushrooms) of Leucoagaricus as well as microscopic features such as the lack of a germ pore in Leucoagaricus species. As a result of the similarities and disagreement on taxonomy, many of the species within these genera have formerly been classified in the other and may still be known by previous classifications. For instance the species Leucoagaricus gongylophorus is cultivated by fungus-growing ants but was formerly known as Leucocoprinus gongylophorus whilst other species cultivated by the lesser attine ants are still classified as undescribed Leucocoprinus species.
Rhodoarrhenia is a genus of fungi in the family Bolbitiaceae. Most species of the genus Rhodoarrhenia have a tropical or subtropical distribution. The genus was circumscribed by mycologist Rolf Singer in 1963. He made R. pezizoidea the type species; in its taxonomic history, this fungus had been placed in the genera Merulius, Campanella, Rimbachia, and Arrhenia by various authors.
Pseudoarmillariella is a genus of fungi in the family Hygrophoraceae. The genus contains three species found in Central America, North America, and Asia. Pseudoarmillariella was described by mycologist Rolf Singer in 1956.
Clitocybula is a genus of mushroom-forming fungi in the family Porotheleaceae but was originally classified within Marasmiaceae. The genus was circumscribed by Georges Métrod in 1952. Species in the genus are commonly known as "coincaps".
Coprinites is an extinct monotypic genus of gilled fungus in the Agaricales family Agaricaceae. At present it contains the single species Coprinites dominicana.
Pseudoclitocybe cyathiformis, commonly known as the goblet funnel cap, is a species of fungus in the family Pseudoclitocybaceae, and the type species of the genus Pseudoclitocybe. It was first described scientifically as Agaricus cyathiformis by Jean Baptiste François Pierre Bulliard in 1786, and later transferred to the genus Pseudoclitocybe by Rolf Singer in 1956. The fungus is found in North America and Europe.
Amparoina spinosissima is a species of fungus in the family Tricholomataceae, and the type species of the genus Amparoina. It was originally named Mycena spinosissima by mycologist Rolf Singer in 1951, who had originally found the species in Argentina in 1949. He transferred it to Amparoina in 1958.
Callistosporium palmarum is a species of fungus in the family Callistosporiaceae, and the type species of the genus Callistosporium. Originally named Gymnopus palmarum by William Alphonso Murrill in 1939, the species was transferred to the genus Callistosporium by Rolf Singer in 1944.
Xanthoconium stramineum is a species of bolete fungus and the type species of the genus Xanthoconium. First described as a species of Gyroporus by William Alphonso Murrill in 1940, it was placed in its current genus by Rolf Singer in 1944.
Pseudotricholoma umbrosum, commonly known as the amyloid tricholoma, is a species of fungus in the family Tricholomataceae, and the type species of the genus Pseudotricholoma. It was first described scientifically by mycologists Alexander H. Smith and Maurice B. Walters in 1943 as a species of Tricholoma. Rolf Singer transferred it to Porpoloma in 1962. The mushroom is found in North America, where it fruits singly or in small groups under conifer trees. Although it resembles a Tricholoma species, it is distinguished from that genus by its amyloid spores.
Amylocystis lapponica is a species of bracket fungus in the family Fomitopsidaceae, and the type species of genus Amylocystis. It produces medium-sized, annual fruit bodies that are soft, and have a strong, distinct smell. The fungus is a saprophyte that feeds on coniferous wood of logs lying on the ground, and causes brown rot. It is a rather rare species that only occurs in old-growth forest.
