Fungi named in 1920

Laetiporus sulphureus is a species of bracket fungus (fungi that grow on trees). Its common names include sulphur polypore, sulphur shelf, and chicken-of-the-woods. Its fruit bodies grow as striking golden-yellow shelf-like structures on tree trunks and branches. Old fruitbodies fade to pale beige or pale grey. The undersurface of the fruit body is made up of tubelike pores rather than gills. Found in Europe and North America, L. sulphureus is a saprophyte and occasionally a weak parasite, causing brown cubical rot in the heartwood of trees on which it grows. Unlike many bracket fungi, it is

Formerly Russula mairei (Singer), and commonly known as the beechwood sickener, the now re-classified fungus Russula nobilis (Velen.) is a basidiomycete mushroom of the genus Russula. This group of mushrooms are noted for their brittle gills and bright colours.

Armillaria cepistipes is a common wood-rotting basidiomycete fungus found in most forests in Central Europe. Armillaria cepistipes is a species of mushroom in the family Physalacriaceae. This is a weakly plant pathogenic species that is typically found growing at the base of deciduous trees that have previously been stressed by another pathogen. The mycelium of the fungus is bioluminescent.

Ramaria pallida is a coral mushroom in the family Gomphaceae. It is found in North America.

Gloiothele is a genus of fungi in the Peniophoraceae family. The genus was circumscribed by mycologist Giacomo Bresadola in 1920.

Mycena flavescens is a species of Mycenaceae fungus. It was first described scientifically by the Czech mycologist Josef Velenovský in 1920, based on specimens collected in Mnichovice in 1915. The mushroom is edible.

Aleurodiscus grantii is a species of fungus in the family Stereaceae. Found in the Pacific Northwest region of North America and in Japan, it was described as new to science by mycologist Curtis Gates Lloyd in 1920. He remarked "Formed of little convex sporophores with free but not raised margin, growing caespitose on bark. Microscopic characters, as in A. amorphus. This, by those who rely on the microscope, would probably be referred to Aleurodiscus amorphus but the fruiting bodies are entirely different in shape." The specific epithet honors J.M. Grant, who collected the type specimens in

Amauroderma calcigenum is a polypore fungus in the family Ganodermataceae. It was first described as a species of Polyporus by Miles Joseph Berkeley in 1843. Camille Torrend transferred it to genus Amauroderma in 1920. A. calcigenum is found in Brazil, Guyana, and Venezuela.

Amanita wellsii or the salmon amanita is a species of agaric fungus in the family Amanitaceae. It was described by American mycologist William Alphonso Murrill in 1920, based on collections made in Springfield, New Hampshire in 1917. The specific epithet honors Professor H. L. Wells, who had previously studied the species. The fungus is found in North America with a range extending from the Appalachian Mountains (North Carolina) north to the limit of the distribution of alder in Canada. Fruit bodies grow scattered or in groups on the ground in mixed forests. Its edibility is unknown.
