Pezizomycotina make up most of the Ascomycota fungi and include most lichenized fungi too. Pezizomycotina contains the filamentous ascomycetes and is a subdivision of the
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The de ...
(fungi that form their spores in a sac-like ''ascus''). It 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 that have fruiting bodies visible to the naked eye (exception: genus ''
Neolecta'', which belongs to the
Taphrinomycotina
The Taphrinomycotina are one of three subdivisions constituting the Ascomycota (fungi that form their spores in a sac-like ascus) and is more or less synonymous with the slightly older invalid name Archiascomycetes (sometimes spelled Archaeascom ...

An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or s ...
Ascomycota) has been replaced by the two classes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).
Some important groups in Pezizomycotina include:
Pezizomycetes (the operculate discomycetes),
Leotiomycetes (the inoperculate discomycetes),
Laboulbeniomycetes,
Sordariomycetes,
Dothideomycetes.
''
Paleopyrenomycites'' from the
Early Devonian Rhynie Chert is the oldest known fossil member of Pezizomycotina, although its position within this subdivision is unclear.
