Fungi named in 1948

Macrolepiota procera, the parasol mushroom, is a basidiomycete fungus with a large, prominent fruiting body resembling a parasol. It resembles some toxic species. It is a fairly common species on well-drained soils. It is found solitary or in groups and fairy rings in pastures and occasionally in woodland. It is widespread in temperate regions of Eurasia and possibly North America. It is a well-regarded edible mushroom.

Psilocybe cubensis, commonly known as the magic mushroom, shroom, golden halo, cube, or gold cap, is a species of psilocybin mushroom of moderate potency whose principal active compounds are psilocybin and psilocin. It belongs to the fungus family Hymenogastraceae and was previously known as Stropharia cubensis. It is the best-known psilocybin mushroom due to its wide distribution and ease of cultivation.

Omphalotus olearius, commonly known as the jack-o'-lantern mushroom, is a poisonous orange gilled mushroom that to an untrained eye appears similar to some chanterelles. It is notable for its bioluminescent properties. It is found in woodland areas in Europe, where it grows on decaying stumps, on buried roots or at the base of hardwood trees. A similar, but phylogenetically distinct species found in eastern North America is Omphalotus illudens. Unlike chanterelles, Omphalotus olearius and other Omphalotus species contain the toxin illudin S, and are poisonous to humans. While not typically

Macrolepiota is a genus of white spored, gilled mushrooms of the family Agaricaceae. The best-known member is the parasol mushroom (M. procera). The widespread genus contains about 40 species.

The Bolbitiaceae are a family of mushroom-forming basidiomycete fungi. A 2008 estimate placed 17 genera and 287 species in the family. Bolbitiaceae was circumscribed by mycologist Rolf Singer in 1948.

The Ganodermataceae are a family of fungi in the order Polyporales. As of April 2018, Index Fungorum accepts 8 genera and 300 species in the family. The family was circumscribed by Dutch mycologist Marinus Anton Donk in 1948 to contain polypores with a double spore wall. The inner wall is verruculose (with moderate-sized growths) to ornamented, thickened and usually coloured, while the outer wall is thin and hyaline.

Chlorociboria aeruginascens is a saprobic species of mushroom, commonly known as the blue stain, green elfcup or the green wood cup because of its characteristic small, green, saucer-shaped fruit bodies. The actual fruit bodies are infrequently seen, with the fungus usually observed through the green staining of wood it causes.

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

Microstoma protractum is a species of cup fungus in the family Sarcoscyphaceae. It was first described as a species of Peziza by Elias Magnus Fries in 1851. American mycologist Bessie B. Kanouse assigned it its current name in 1948. The fungus is found in Europe and North America, where it grows as a saprophyte on partially buried sticks and roots.

The Ceratobasidiaceae are a family of fungi in the order Cantharellales. All species within the family have basidiocarps (fruit bodies) that are thin and effused. They have sometimes been included within the corticioid fungi or alternatively within the "heterobasidiomycetes". Species are saprotrophic, but some are also facultative plant pathogens or are associated with orchid mycorrhiza. Genera of economic importance include Ceratobasidium and Rhizoctonia, both of which contain plant pathogenic species causing diseases of commercial crops and turf grass.

Psathyrella pennata, commonly known as the carbon brittlestem, or bonfire brittlestem, is a species of mushroom in the family Psathyrellaceae. It usually fruits during the spring.

The Broomeiaceae are a family of fungi in the order Agaricales. The family is monotypic, and contains the single genus Broomeia, described by English naturalist Miles Joseph Berkeley in 1844, and named for his collaborator, Christopher Edmund Broome. Berkeley designated the type species to be Broomeia congregata. Species of this fungus family can be found in Mexico as well as various parts of Africa.

Hydropus is a genus of fungi in the family Porotheleaceae. The widespread genus contains about 100 species, especially in tropical areas, but is not well represented in temperate regions. About 15 taxa are found in Europe; H. floccipus has the widest distribution in western Europe. Hydropus was circumscribed by Rolf Singer in 1948. Species in the genus have fruit bodies with caps that are mycenoid, collybioid, or omphaloid in form. Most species occur in tropical and subtropical regions, where they grow as saprobes on rotting wood, forest litter, and mosses. Generally, most Hydropus species

Phellinus ferreus is a plant pathogen infecting stone fruit trees.

Dacryopinax is a genus of fungi in the family Dacrymycetaceae. The genus is widespread, especially in tropical regions, and contains about 15 species. Dacryopinax was circumscribed by American mycologist George Willard Martin in 1948. A taxonomic monograph was published by McNabb (1965). Dacryopinax species are common wood inhabiting fungi worldwide, mostly producing brown rot wood decay. Genomic analysis of Dacryopinax primogenitus revealed the loss of genes for class II peroxidases necessary for lignin degradation, supporting observations of a brown rot physiology.

Pholiota spumosa, commonly known as the slender pholiota, is a species of mushroom in the family Strophariaceae. It grows on decaying wood.

Hebeloma helodes is a species of mushroom in the family Hymenogastraceae.

The Gasterellaceae are a family of fungi in the order Boletales. The family contains a single genus Gasterella, which in turn contains the single species Gasterella luteophila, found in the USA. The genus and species were described by American mycologists Sanford Myron Zeller and Leva Belle Walker in 1935; the family by Zeller in 1948.

Sistotrema brinkmannii, a resupinate wood-rotting basidiomycete, is a fungus found in soil, moss, debris, rotten woods as well as woods including seedling roots of Pinus banksiana Lamb. and ectomycorrhizae. No health issues caused by this fungus in human and animals have been reported although it is causative of brown rot. This fungus grows rapidly on malt extract agar (MEA), forming white mats with a faint sweet odour. It is commonly called "chain chlamydospore fungus" because bulbils are formed by chains of its cells that resemble chlamydospores. The basidia of this fungus are urniform and

Pseudocyphellaria glabra is a species of corticolous (bark-dwelling), foliose lichen in the family Peltigeraceae. It has a pale-green upper thallus surface, a white medulla and white pseudocyphellae (tiny pores for gas exchange).

Neopaxillus is a genus of fungi in the family Crepidotaceae. According to the Dictionary of the Fungi (10th edition, 2008), the family contains five species found in Central and South America; a sixth, N. dominicanus, was reported in 2011. It was formerly considered to belong in the family Serpulaceae in the order Boletales, but molecular analysis showed that Neopaxillus is better placed in the Agaricales as a sister group to Crepidotus (of the family Crepidotaceae).

Dacryopinax elegans is a species of jelly fungus in the family Dacrymycetaceae. It was originally formally described as Guepinia elegans by Miles Berkeley and Moses Ashley Curtis in 1849. George Willard Martin transferred it to the genus Dacryopinax in 1948. The fruit bodies have upside-down cups 3–15 millimetres (1⁄8–5⁄8 in) across. Similar species include Guepiniopsis buccina and some in Auricularia. It appears from June to October in the eastern United States west of New England.

Penicillium lapidosum is an anamorph species of the genus of Penicillium which produces patulin.

Morganella is a genus of puffball fungi in the family Lycoperdaceae. The genus name honors American botanist Andrew Price Morgan (1836–1907). The widely distributed genus is prevalent in tropical areas. A 2008 estimate placed nine species in Morganella, but several new species have since been described.
