Pezizomycotina Pezizomycotina is the largest subdivision of Ascomycota, containing the filamentous ascomycetes and most lichenized fungi. It is more or less synonymous with the older taxon Euascomycota. These fungi reproduce by fission rather than budding. Thi ...

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 ...

Some are phytopathogens that can cause leaf, stem, and root diseases in a wide variety of hosts, while other genera can cause diseases in

and mammals. The name Sordariomycetes is derived from the Latin ''sordes'' (filth) because some species grow in animal feces, though growth habits vary widely across the class. In 2013, it consisted of 3 subclasses, 12 orders, 600 genera and 3000 species, Then by 2015, it had 3 subclasses, 28 orders, 90 families and 1344

listed 26,295 species in Sordariomycetes. Sordariomycetes generally produce their asci in perithecial fruiting bodies. Sordariomycetes are also known as Pyrenomycetes, from the Greek - 'the stone of a fruit' - because of the usually somewhat tough texture of their tissue. Sordariomycetes possess great variability in morphology, growth form, and habitat. Most have perithecial (flask-shaped) fruiting bodies, but ascomata can be less frequently cleistothecial (such as in the genera '' Anixiella'', '' Apodus'', '' Boothiella'', '' Thielavia'' and '' Zopfiella''). Fruiting bodies may be solitary or gregarious, superficial, or immersed within stromata or tissues of the substrates and can be light to bright or black. Members of this group can grow in soil, dung,
