Ascomycota, subdivision Ascomycota, Ascomycotina, subdivision Ascomycotina

a large subdivision of Eumycota including Hemiascomycetes and Plectomycetes and Pyrenomycetes and Discomycetes; sac fungi; in some classification systems considered a division of the kingdom Fungi

• division — (botany) taxonomic unit of plants corresponding to a phylum

• Helotiales, order Helotiales — order of fungi having asci in a disk- to goblet-shaped apothecium
• Tuberales, order Tuberales — small order of fungi belonging to the subdivision Ascomycota having closed underground ascocarps
• sac fungus — any of various ascomycetous fungi in which the spores are formed in a sac or ascus
• Ascomycetes, class Ascomycetes — large class of higher fungi coextensive with division Ascomycota: sac fungi
• ascomycete, ascomycetous fungus — any fungus of the class Ascomycetes (or subdivision Ascomycota) in which the spores are formed inside an ascus
• Hemiascomycetes, class Hemiascomycetes — class of fungi in which no ascocarps are formed: yeasts and some plant parasites
• Plectomycetes, class Plectomycetes — class of fungi in which the fruiting body is a cleistothecium (it releases spores only on decay or disintegration)
• Pyrenomycetes, class Pyrenomycetes — class of fungi in which the fruiting body is a perithecium; includes powdery mildews and ergot and neurospora

• Eumycota, division Eumycota — true fungi; eukaryotic heterotrophic walled organisms; distinguished from Myxomycota (funguslike slime molds): comprises subdivisions Mastigomycotina; Zygomycotina; Ascomycotina; Basidiomycotina; Deuteromycotina (imperfect fungi)
