Phylum Ascomycota Cavalier-Smith

[ascus fungi]

This Phylum, or Division, is also known as the ascomycetes (it was once a Class). This group includes the morels, false morels, cup fungi, various flask fungi, most lichens, yeasts, molds, and others. All of these sac fungi have their sexual spores produced inside of a sac-shaped cell, the ascus. The phylum contains 3 subphyla and 16 classes. Classification follows Lumbsch and Huhndorf (2010).

  1. Taphrinomycotina (4 classes)
    • Neolectomycetes (1 order)
    • Pneumocystidomycetes (1 order)
    • Schizosaccharomycetes (1 order)
    • Taphrinomycetes (1 order)
  2. Saccharomycotina (1 class)
    • Saccharomycetes (1 order)
  3. Pezizomycotina (11 classes)
    • Arthoniomycetes (1 order)
    • Dothideomycetes (11 orders)
    • Eurotiomycetes (7 orders)
    • Geoglossomycetes (1 order)
    • Laboulbeniomycetes (2 orders)
    • Lecanoromycetes (10 orders)
    • Leotiomycetes (5 orders)
    • Lichinomycetes (1 order)
    • Orbiliomycetes (1 order)
    • Pezizomycetes (1 order)
    • Sordariomycetes (18 orders)
    • Uncertain placement (3 orders and 1 family)
  4. Uncertain placement (many families and genera)
