Fungi named in 1955

Ascosphaera apis is a species of fungus belonging to the family Ascosphaeraceae. It was one of the first entomopathogen genomes to be sequenced. It has a cosmopolitan distribution. It causes the chalkbrood diseases in bees, which rarely kills infected colonies but can weaken them and lead to reduced honey yields and susceptibility to other pests and diseases.

Cheimonophyllum is a genus of fungi in the family Cyphellaceae. The widely distributed genus contains three species.

Laxitextum is a genus of fungi in the family Hericiaceae. The widespread genus contains three species. It was circumscribed by Paul Lewis Lentz in 1955. Species in the genus have fruit bodies that are effused (stretched out flat) to reflexed (with edges turned up) and a smooth hymenium. Molecular analysis shows that the genus groups in a clade with the genera Hericium and Dentipellis.

Bankera is a genus of four species of tooth fungi in the family Bankeraceae. The genus was first circumscribed in 1951 by William Chambers Coker and Alma Holland Beers, but this publication was invalid according to the rules of botanical nomenclature. It was later published validly by Zdeněk Pouzar in 1955. The type species is B. fuligineoalba. The genus is ectomycorrhizal with gymnosperms, usually with trees from the pine family. Fruitbodies of Bankera species are fleshy, usually with a centrally-placed stipe, and greyish-brown spines on the hymenial undersurface. The texture of the flesh

Ascosphaera is a genus of fungi in the family Ascosphaeraceae. It was described in 1955 by mycologists Charles F. Spiltoir and Lindsay S. Olive. Members of the genus are insect pathogens. The type species, A. apis, causes chalkbrood disease in honey bees. The reproductive ascospores of the fungus are produced within a unique structure, the spore cyst, or sporocyst.

Talaromyces is a genus of fungi in the family Trichocomaceae. Described in 1955 by American mycologist Chester Ray Benjamin, species in the genus form soft, cottony fruit bodies (ascocarps) with cell walls made of tightly interwoven hyphae. The fruit bodies are often yellowish or are surrounded by yellowish granules. A 2008 estimate placed 42 species in the genus, but several new species have since been described. This genus contains the teleomorph of Penicillium.

Russula subnigricans, known as the rank russula, or Nise-Kurohatsu (Japanese), meaning "false blackening russula" is a basidiomycete mushroom of the genus Russula found in East Asia. It is poisonous.

Lactarius acutus is a member of the large milk-cap genus Lactarius in the order Russulales. Found in Guinea, the species was described in 1955 by French botanist Roger Heim.

The Ascosphaeraceae are a family of fungi in the Ascomycota, class Eurotiomycetes.

Westerdykella is a genus of fungi in the family Sporormiaceae.

Zeora confusa is a species of corticolous (bark-dwelling) crustose lichen in the family Lecanoraceae. It was described from Sweden in 1955 as Lecanora confusa. A later molecular study of Lecanora supported resurrecting the genus Zeora for the former Lecanora symmicta group, and the species was transferred accordingly. It grows on the bark of trees and shrubs, particularly in coastal areas of Europe and North America. First identified in Sweden in 1955, this small, greenish-grey lichen forms smooth patches and is recognized by its pale yellowish-green reproductive structures (apothecia). Once

Hygroaster is a genus of mushroom-forming fungi in the family Hygrophoraceae. The genus was described by mycologist Rolf Singer in 1955.

Gymnopilus purpuratus is a species of agaric fungus in the family Hymenogastraceae. It grows in clusters on dead wood, tree stumps and wood chip mulch. It is widely distributed and has been recorded in Argentina, Australia, Chile, New Zealand, the UK and Germany. It has a broadly convex cap covered in small dry reddish-brown scales, a stout yellow stem beneath reddish brown, wine-red to purple vertical fibres, and a thick rusty orange spore print. The fruitbodies can stain greenish, blue and purple when damaged, and the species is psychoactive. A chemical analysis carried out by Jochen Gartz

Dennisiomyces is a genus of fungi in the family Tricholomataceae. Described by mycologist Rolf Singer in 1955, the genus contains five species found in South America. The genus name of Dennisiomyces is in honour of Richard William George Dennis (1910 - 2003), British botanist (mycology) and plant pathologist.

Collodiscula is a genus of fungi in the family Xylariaceae. This is a monotypic genus, containing the single species Collodiscula japonica. Collodiscula japonica's anamorph is Acanthodochium collodisculae.

Aspergillus deflectus is a species of fungus in the genus Aspergillus. It produces a group of antimicrobial chemical compounds known as deflectins. Aspergillus deflectus is in rare cases pathogenic. It is from the Usti section.

Septoria selenophomoides is a fungal plant pathogen infecting orchids. It causes leaf spots, starting with small yellowish lesions on the plant's leaves and darkening to brown or black. If the infection develops further, the leaves and fruit fall from the orchid and spread the infection.

Homaromyces is a genus of fungi in the family Laboulbeniaceae. A monotypic genus, Homaromyces contains the single species Homaromyces epieri.

Hidakaea is a genus of fungi in the Microthyriaceae family; according to the 2007 Outline of Ascomycota, the placement in this family is uncertain. This is a monotypic genus, containing the single species Hidakaea tumidula.

Gymnopilus filiceus is a species of mushroom in the family Hymenogastraceae.
