Phylum Basidiomycota Whittaker ex Moore

[basidium fungi]

This Phylum, or Division, is also known as the basidiomycetes (previously at the level of Class). This group includes most of the mushrooms and jelly fungi, as well as the plant parasites known as rusts and smuts. All of these club fungi have their sexual spores produced on the outside of a club-shaped cell, the basidium. Another character of this group, the clamp connection, found at septa, seems to assist with nuclear division of the dikaryon (bi-nucleate cells). There are three Subphyla (Subdivisions).

  • Agaricomycotina (4 classes, 28 orders)
    1. Agaricomycetes
    2. Dacrymycetes
    3. Tremellomycetes
    4. Wallemiomycetes (Wallemia, Geminibasidium)
  • Pucciniomycotina (9 classes, 20 orders, 37 families)
    1. Agaricostilbomycetes
    2. Atractiellomycetes
    3. Classiculomycetes
    4. Cryptomycocolacomycetes
    5. Cystobasidiomycetes
    6. Microbotryomycetes
    7. Mixiomycetes
    8. Pucciniomycetes
    9. Tritirachiomycetes
  • Ustilaginomycotina (2 classes, 10 orders, 27 families)
    1. Exobasidiomycetes
    2. Ustilaginomycetes

Nomenclature
  • Basidiomycota Whittaker ex Moore, Botanica Marina 23(6): 371 (1980). Type: none designated.
Taxonomy
Some jelly fungi are now found in the Agaricomycetes: the ground-dwelling and ectomycorrhizal Sebacina (with Tremellodendron) have been moved to the Sebacinales; Auricularia, Exidia and relatives are now in Auriculariales. Entorrhiza (Entorrhizomycetes) are either basal to the Basidiomycota or to the Dikarya.
