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 def ...
(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
''Neolecta'' is a genus of ascomycetous fungi that have fruiting bodies in the shape of unbranched to lobed bright yellowish, orangish to pale yellow-green colored, club-shaped, smooth, fleshy columns up to about 7 cm tall. The species share ...

See the taxobox for a list of the classes that make up the Pezizomycotina. The old class Loculoascomycetes (consisting of all the
bitunicate Ascomycota) has been replaced by the two classes

Pezizomycetes are a class of fungi within the division Ascomycota.
Pezizomycetes are apothecial fungi, meaning that their spore-producing/releasing bodies (ascoma) are typically disk-like, bearing on their upper surfaces a layer of cylindrical s ...
