Editing Ascomycota (section)

== Outdated taxon names ==
Several outdated taxon names—based on morphological features—are still occasionally used for species of the Ascomycota. These include the following sexual ([[Teleomorph, anamorph and holomorph|teleomorph]]ic) groups, defined by the structures of their sexual [[Sporocarp (fungi)|fruiting bodies]]: the [[Discomycetes]], which included all species forming [[ascocarp|apothecia]]; the [[Pyrenomycetes]], which included all sac fungi that formed [[ascocarp|perithecia]] or [[ascocarp|pseudothecia]], or any structure resembling these morphological structures; and the Plectomycetes, which included those species that form [[ascocarp|cleistothecia]]. [[Hemiascomycetes]] included the yeasts and yeast-like fungi that have now been placed into the [[Saccharomycotina]] or [[Taphrinomycotina]], while the [[Euascomycetes]] included the remaining species of the Ascomycota, which are now in the [[Pezizomycotina]], and the [[Neolecta]], which are in the Taphrinomycotina.

Some ascomycetes do not reproduce sexually or are not known to produce [[ascus|asci]] and are therefore [[Teleomorph, anamorph and holomorph|anamorph]]ic species. Those anamorphs that produce [[Conidium|conidia]] (mitospores) were previously described as [[mitosporic Ascomycota]]. Some taxonomists placed this group into a separate [[form classification|artificial phylum]], the [[Deuteromycota]] (or "Fungi Imperfecti"). Where recent [[Molecular phylogenetics|molecular analyses]] have identified close relationships with ascus-bearing taxa, anamorphic species have been grouped into the Ascomycota, despite the absence of the defining ascus. Sexual and asexual isolates of the same species commonly carry different [[Binomial nomenclature|binomial]] species names, as, for example, ''[[Aspergillus nidulans]]'' and ''Emericella nidulans'', for asexual and sexual isolates, respectively, of the same species.

Species of the Deuteromycota were classified as Coelomycetes if they produced their conidia in minute flask- or saucer-shaped conidiomata, known technically as ''pycnidia'' and ''acervuli''.<ref>{{harvnb|Alexopoulos|Mims|Blackwell|1996|p=233}}</ref> The [[Hyphomycetes]] were those species where the [[conidiophore]]s (''i.e.'', the hyphal structures that carry conidia-forming cells at the end) are free or loosely organized. They are mostly isolated but sometimes also appear as bundles of cells aligned in parallel (described as ''synnematal'') or as cushion-shaped masses (described as ''sporodochial'').<ref>{{harvnb|Alexopoulos|Mims|Blackwell|1996|pp=218–222}}</ref>
