(Gr. basis: base; mykês: fungus) A large phylum of fungi, 22 000 to 25 000 species, that includes many mushrooms, the bracket fungi, puffballs, etc., as well as important microscopic forms, such as the parasitic rust fungi and smuts of crops. They reproduce by basidia, which are typically club-shaped and produce spores at the tips of stalklike projections.

The Phylum Basidiomycota is further organized into finer groupings including:

The Agaricostilbomycetes are class of fungi in the Pucciniomycotina subphylum of the Basidiomycota. The class consists of 2 orders, 3 families, 10 genera, and 47 species. [more]


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 34 species. [more]


Basidiomycota () is one of two large phyla that, together with the Ascomycota, comprise the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. More specifically the Basidiomycota include these groups: mushrooms, puffballs, stinkhorns, bracket fungi, other polypores, jelly fungi, boletes, chanterelles, earth stars, smuts, bunts, rusts, mirror yeasts, and the human pathogenic yeast Cryptococcus. Basically, Basidiomycota are filamentous fungi composed of hyphae (except for yeasts), and reproducing sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores. However, some Basidiomycota reproduce asexually in addition or exclusively. Basidiomycota that reproduce asexually (discussed below) can be recognized as members of this phylum by gross similarity to others, by the formation of a distinctive anatomical feature (the clamp connection - see below), cell wall components, and definitively by phylogenetic molecular analysis of DNA sequence data.

The Dacrymycetes are a class consisting of only one family of jelly fungi, which has imperforate parenthesomes and basidia that are usually branched. There are 9 genera and 101 species in the Dacrymycetaceae family. [more]










The Tremellomycetes are a class of dimorphic fungi. Some species have a gelatinous fruiting body or a sacculate parenthesome. There are 3 orders, 11 families, 50 genera, and 377 species in the Tremellomycetes. [more]


The Pucciniomycetes (formerly known as the Urediniomycetes) are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains 5 orders, 21 families, 190 genera, and 8016 species. It includes several important plant pathogens causing forms of fungal rust. [more]


Ustilaginomycetes is the class of true smut fungi. They are plant parasites with about 1400 recognised species in 70 genera. [more]

At least 2,525 species and subspecies belong to the Class Ustilaginomycetes.
