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. 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).
