Overview
Pezizomycotina contains the filamentous ascomycetes and is a subphylum of the Ascomycota (fungi which form their spores in a sac-like ascus). It is more or less synonymous with the older taxon Euascomycota.1] 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 Note that the old class Loculoascomycetes (consisting of all the bitunicate Ascomycota) has been replaced by the two classes Eurotiomycetes and Dothideomycetes. The rest of the Pezizomycotina also include the previously defined hymenial groups Discomycetes (now Leotiomycetes) and Pyrenomycetes (Sordariomycetes).

Taxonomy
The Subphylum Pezizomycotina is a member of the Phylum Ascomycota. Here is the complete "parentage" of Pezizomycotina:
- Domain: Eukaryota
Whittaker & Margulis,1978 - eukaryotes
- Kingdom: Fungi
T.L. Jahn & F.F. Jahn, 1949 ex R.T. Moore, 1980 - Fungi
- Subkingdom: Dikarya

- Phylum: Ascomycota

- Subphylum: Pezizomycotina O.E. Eriksson & K. Winka, 1997
- Phylum: Ascomycota
H.C. Bold, 1957 ex T. Cavalier-Smith, 1998 - Sac Fungi
- Subkingdom: Dikarya

- Kingdom: Fungi
T.L. Jahn & F.F. Jahn, 1949 ex R.T. Moore, 1980 - Fungi
The Subphylum Pezizomycotina is further organized into finer groupings including:
- Class (10): Arthoniomycetes · Dothideomycetes · Eurotiomycetes · Laboulbeniomycetes · Lecanoromycetes · Leotiomycetes · Lichinomycetes · Orbiliomycetes · Pezizomycetes · Sordariomycetes
Classes
Arthoniomycetes
Arthoniomycetes are a class of ascomycete fungi. It includes the single order Arthoniales. Most of the taxa in this class are tropical and subtropical lichens. [more]
Dothideomycetes
Dothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1300 genera and over 19,000 known species. Traditionally, most of its members were included in the loculoascomycetes, which is not part of the currently accepted classification. This indicates that several traditional morphological features in the class are not unique and DNA sequence comparisons are important to define the class. [more]
Eurotiomycetes
The Eurotiomycetes is a class of ascomycetes within the subphylum Pezizomycotina. [more]
Laboulbeniomycetes
The Laboulbeniomycetes are a unique group of fungi 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 is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci (spore-bearing cells) of the Lecanoromycetes most often release spores by rostrate dehiscence. [more]
Leotiomycetes
Lichinomycetes
Lichinomycetes are a class of ascomycete fungi. It includes the single order Lichinales. Most species are lichenized. [more]
Orbiliomycetes
Orbiliomycetes are a class of fungi in the Ascomycota. It includes the single order Orbiliales, which in turn includes the single family Orbiliaceae. [more]
Pezizomycetes
Pezizomycetes are a class of fungi within the phylum Ascomycota. [more]
Sordariomycetes
The Sordariomycetes are a class of fungi in the subdivision Pezizomycotina (Ascomycota), consisting of 15 orders, 64 families, 1119 genera, and 10564 species. [more]
At least 17,459 species and subspecies belong to the Class Sordariomycetes.
