Fungi named in 1946

Agaricus bisporus, commonly known as the cultivated mushroom, is a basidiomycete mushroom native to grasslands in Eurasia and North America. It is cultivated in more than 70 countries and is one of the most commonly and widely consumed mushrooms in the world. It has two color states while immature – white and brown – both of which have various names, with additional names for the mature state, such as chestnut, portobello, portabellini, button, cremini, and champignon de Paris (see Names below). Some poisonous lookalikes in the wild, such as Entoloma sinuatum, may appear similar. Agaricus

Kuehneromyces mutabilis (synonym: Pholiota mutabilis), commonly known as the sheathed woodtuft, is a species of fungus that grows in clumps on dead wood. It is edible but strongly resembles the deadly poisonous Galerina marginata.

The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith.

Psilocybe cyanescens, commonly known as the wavy cap or potent psilocybe, is a species of potent psychedelic mushroom. The main compounds responsible for its psychedelic effects are psilocybin and psilocin. It belongs to the family Hymenogastraceae. A formal description of the species was published by Elsie Wakefield in 1946 in the Transactions of the British Mycological Society, based on a specimen she had recently collected at Kew Gardens. She had begun collecting the species as early as 1910. The mushroom is not generally regarded as being physically dangerous to adults. Psilocybe

Kuehneromyces is a genus of agaric fungi in the family Strophariaceae. The genus was circumscribed by mycologists Rolf Singer and Alexander H. Smith in 1946. The genus name of Kuehneromyces is in honour of Robert Kühner (1903–1996), who was a French mycologist most notable for reviewing many agaric. The best known species in the genus is K. mutabilis, the sheathed woodtuft, which – despite closely resembling the deadly galerina, Galerina marginata, – is a popular edible mushroom in Europe that can also be cultivated on wood.

Squamanita is a genus of parasitic fungi in the family Squamanitaceae. Basidiocarps (fruit bodies) superficially resemble normal agarics (gilled mushrooms) but emerge from parasitized fruit bodies of deformed host agarics.

Callistosporium luteo-olivaceum is a species of agaric fungus in the family Callistosporiaceae. It was originally described in 1859 as Agaricus luteo-olivaceus by Miles Joseph Berkeley and Moses Ashley Curtis in 1859. Rolf Singer transferred it to Callistosporium in 1946. The fungus has an extensive synonymy. The brownish mushroom has caps up to 4.5 centimetres (1+3⁄4 in) wide. The gills are yellowish and close. The stem is 7 cm (2+3⁄4 in) long, fibrillose and hollow, with yellowish tomentum near the base. The spores are colorless, producing a whitish print or a yellow color in ammonia. The

Psathyrella bipellis is a species of mushroom in the family Psathyrellaceae.

The Asterinaceae are a family of fungi in the class Asterinales.

The Meliolaceae are a family of fungi in the order Meliolales. Mostly tropical in distribution, species in this family are biotrophic on the leaves and stems of plants. Despite this, most species do not cause extensive damage to the host plant, and are not generally considered to be of economic significance.

Squamanita schreieri is a species of fungus in the order Agaricales and the type species of the genus Squamanita. It is parasitic on basidiocarps (fruit bodies] of the ectomycorrhizal fungi Amanita solitaria and A. strobiliformis, replacing their caps with its own. The species was first described scientifically by Swiss mycologist Emil J. Imbach in 1946. It is only known from a few sites in central mainland Europe and threats to its habitat (hardwood forests) have resulted in the species being assessed as globally "endangered" on the IUCN Red List of Threatened Species.

Elsinoë mangiferae, common name "mango scab", is also known Denticularia mangiferae or Sphaceloma mangiferae (anamorph). It is an ascomycete plant pathogen native to tropical regions and specific for survival on only one host, the mango. Originally described in 1943 from Florida and Cuba specimens, this pathogen has since spread worldwide and is becoming a pathogen of great concern for the mango industries in Australia and India. The species was first described formally in 1946.
