Overview
Pezizomycotina is a subphylum of the (fungi which form their spores in a sac-like ascus) and is more or less synonymous with the older taxon Euascomycota. These fungi reproduce by fission rather than budding and this subdivision includes almost all the ascus fungi which have fruiting bodies visible to the naked eye (exception: genus Neolecta which belongs to the Taphrinomycotina).
See the taxobox for a list of the classes which make up the Pezizomycotina. Note that the old class Loculoascomycetes (consisting of all the bitunicate Ascomycota) has been replaced by the two classes Chaetothyriomycetes and Dothideomycetes. The rest of the Pezizomycotina can be called Hymenoascomycetes.

(Linnaeus, 1753) Nees, 1817
- Subkingdom: Dikarya

The Subphylum Pezizomycotina is further organized into finer groupings including:
- Class (10): Arthoniomycetes · Dothideomycetes · Eurotiomycetes · Laboulbeniomycetes · Lecanoromycetes · Leotiomycetes · Lichinomycetes · Orbiliomycetes · Pezizomycetes · Sordariomycetes
Classes
Arthoniomycetes
Dothideomycetes
Dothideomycetes is a of ascomycete fungi. It comprises about 50 families, 650 genera and 6300 known species. Traditionally most of its members were included in the clade Loculoascomycetes. The class contains several important plant pathogens (like Phaeosphaeria nodorum and Venturia inaequalis). [more]
Eurotiomycetes
Eurotiomycetes are a class of within the Pezizomycotina clade. [more]
Laboulbeniomycetes
The Laboulbeniomycetes are a unique group of that are apparent external parasites of insects and other arthropods, both terrestrial and aquatic. These fungi are minute; their fruiting bodies commonly measure less than one millimeter. They live on the antennae, the mouthparts or other body regions of their arthropod hosts. Although several species of Laboulbeniomycetes have more or less extensive, root-like hyphal systems (haustoria) inside their hosts, as a group these fungi are apparently harmless to the animals they live on. These fungi are usually apparent only on adult hosts; apparently immature arthropods eliminate them during ecdysis (adult arthropods no longer molt). Some fungi in the Laboulbeniomycetes have separate female and male individuals, like Herpomyces. [more]
Lecanoromycetes
Lecanoromycetes are a class of fungi, commonly known as the lichens and rostrate asci. [more]
Leotiomycetes
Lichinomycetes
Orbiliomycetes
Pezizomycetes
Pezizomycetes are a class of within the phylum Ascomycota. [more]
Sordariomycetes
Sordariomycetes is a class of the subdivision, , which includes ascomycetous fungi. [more]
At least 6,597 species and subspecies belong to the Class Sordariomycetes.
