Monotypic fungus classes

Pezizomycetes are a class of fungi within the division Ascomycota.

Saccharomycetes belongs to the Ascomycota division of the kingdom Fungi. It is the only class in the subdivision Saccharomycotina, the budding yeasts. Saccharomycetes contains a single order, Saccharomycetales.

The Taphrinomycetes are a class of ascomycete fungi belonging to the subdivision Taphrinomycotina. It includes the single order Taphrinales, which includes 2 families, 8 genera and 140 species.

The Mixiomycetes are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Mixiales, which in turn contains a single family, the Mixiaceae that circumscribes the monotypic genus Mixia. Only one species has been described to date, Mixia osmundae; this species was originally named Taphrina osmundae by Japanese mycologist Toji Nishida in 1911. It is characterized by having multinucleate hyphae, and by producing multiple spores on sporogenous cells.

The Agaricostilbomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class consists of a single order, six families, and 15 genera. Its type genus, Agaricostilbum was originally placed in Ascomycota, and later, Agaricomycotina, before being placed in Pucinniomycotina.

The Schizosaccharomycetes are a class in the kingdom of fungi. It contains the order Schizosaccharomycetales, the fission yeasts. The genus Schizosaccharomyces is a broad and ancient clade within Ascomycota including five known fission yeast: Schizosaccharomyces pombe, Schizosaccharomyces japonicius, Schizosaccharomyces octosporus, and Schizosaccharomyces cryophilus, and Schizosaccharomyces osmophilus.

The Cryptomycocolacomycetes are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Cryptomycocolacales, which in turn contains the single family Cryptomycocolacaceae. The family has two monotypic genera.

So far, the class has only one described order, Archaeorhizomycetales, family, Archaeorhizomycetaceae, and genus, Archaeorhizomyces. The class was first described by a team led by Anna Rosling in 2011. Species in the class are globally distributed, and grow in soil and around roots. Specific known host trees of various Archaeorhizomyces species include he

The Atractiellomycetes are class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class consists of a single order, the Atractiellales, which contains 3 families, 10 genera, and 58 species.

The Pneumocystidomycetes are a class of ascomycete fungi. It includes the single order Pneumocystidales, which contains the single monotypic family Pneumocystidaceae, which in turn contains the genus Pneumocystis, causative agent of Pneumocystis pneumonia.

The Wallemiomycetes are a class of fungi in the division Basidiomycota. It consists of the single order Wallemiales, containing the single family Wallemiaceae, which in turn contains the single genus Wallemia. The phylogenetic origin of the lineage was placed to various parts of Basidiomycota, but according to the analysis of a larger dataset it is a sister group of Agaricomycotina. The genus contains species of xerophilic molds that are found worldwide. The seven described species (W. sebi, W. ichthyophaga, W. muriae, W. mellicola, W. canadensis, W. tropicalis, a

The Classiculomycetes are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Classiculales, which in turn contains the single family Classiculaceae. The family contains two monotypic genera.

The Spiculogloeomycetes are a class of fungi in the subdivision Pucciniomycotina of the Basidiomycota. The class consists of a single order, the Spiculogloeales, together with an additional, unassigned genus, Meniscomyces. Many species are currently known only from their yeast states. Species in the genus Spiculogloea form hyphal states that produce auricularioid (laterally septate) basidia and are parasitic on other fungi.
