Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (Ascomycota). It is the second-largest class of Ascomycota, with a worldwide distribution that mostly accommodates terrestrial based taxa, although several can also be found in aquatic habitats. Some are phytopathogens that can cause leaf, stem, and root diseases in a wide variety of hosts, while other genera can cause diseases in arthropods 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

Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci (spore-bearing cells) of the Lecanoromycetes most often release spores by rostrate dehiscence. The group is monophyletic (composed only of all the descendants of a common ancestor).

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. This subdivision includes almost all ascus fungi that have fruiting bodies visible to the naked eye, except for the genus Neolecta, which belongs to Taphrinomycotina. 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 The old class Loculoascomycetes (consisting of all the bitunicate Ascomycota) has been replaced by the two classes

Eurotiomycetes is a large class of ascomycetes with cleistothecial ascocarps within the subphylum Pezizomycotina, currently containing around 3810 species according to the Catalogue of Life. It is the third largest lichenized class, with more than 1200 lichen species that are mostly bitunicate in the formation of asci. It contains most of the fungi previously known morphologically as "Plectomycetes".

Dothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1,300 genera and over 19,000 known species. Wijayawardene et al. in 2020 added more orders to the class. Traditionally, most of its members were included in the loculoascomycetes, which is not part of the currently accepted classification. This indicates that several traditional morphological features in the class are not unique and DNA sequence comparisons are important to define the class. The designation loculoascomycetes was first proposed for all fungi which have ascolocular

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 spore-producing cells called asci, from which the spores are forcibly discharged. Important groups include: cup fungi (Peziza), morels, Elfin saddles, and truffles.

The Leotiomycetes are a class of ascomycete fungi. Some members of the class are known as plant pathogens.

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 Archaeascomycetes; archea = ancient). Recent molecular studies suggest that the group is monophyletic and basal to the rest of the Ascomycota. The major taxa are Schizosaccharomycetes, Taphrinomycetes, Neolectomycetes, and Pneumocystis. The Schizosaccharomycetes are the yeasts (e.g. Schizosaccharomyces) that reproduce by fission rather than budding, unlike most

The Taphrinomycetes are a class of ascomycete fungi belonging to the subdivision Taphrinomycotina. It includes the single order Taphrinales, which includes 2 families, 8 genera and 140 species.

Arthoniomycetes are a class of ascomycete fungi. It includes two orders: Arthoniales and Lichenostigmatales. Most of the taxa in these orders are tropical and subtropical lichens.

Saccharomycotina is a subdivision (subphylum) of the division (phylum) Ascomycota in the kingdom Fungi. It comprises most of the ascomycete yeasts. The members of Saccharomycotina reproduce by budding and they do not produce ascocarps (fruiting bodies). The subdivision includes a single class: Saccharomycetes, which again contains a single order: Saccharomycetales. Notable members of Saccharomycotina are the baker's yeast Saccharomyces cerevisiae and the genus Candida that includes several human pathogens.

The order Sordariales is one of the most diverse taxonomic groups within the Sordariomycetes (subdivision Pezizomycotina, division Ascomycota). Species in the order Sordariales have a broad range of ecological diversity, containing lignicolous, herbicolous and coprophilous taxa. Most Sordariales are saprobic, producing solitary perithecial ascomata. They are commonly found on dung or decaying plant matter. The order contains a number of ecologically important species, including the model filamentous fungal genera Podospora and Neurospora, as well as potentially industrial-relevant fungi, such

The Schizosaccharomycetes are a class in the kingdom of fungi. It contains the order Schizosaccharomycetales, the fission yeasts. The genus Schizosaccharomyces is a broad and ancient clade within Ascomycota including five known fission yeast: Schizosaccharomyces pombe, Schizosaccharomyces japonicius, Schizosaccharomyces octosporus, and Schizosaccharomyces cryophilus, and Schizosaccharomyces osmophilus.

The Pyrenulales are an order of ascomycetous fungi within the class Eurotiomycetes and within the subphylum Pezizomycotina.

Hypocreomycetidae is a subclass of sac fungi. It is a highly diverse group of fungi with species from various habitats. This subclass has been reported as pathogenic, endophytic, parasitic, saprobic, fungicolous, lichenicolous, algicolous, coprophilous (animal dung) and insect fungi from aquatic and terrestrial habitats. The members of Hypocreomycetidae have light colored perithecia, non-amyloid or amyloid ascal rings, or those which lack apical rings and most taxa lack true paraphyses (Zhang et al. 2006). Hypocreomycetidae was established by Eriksson and Winka (1997) based on morphology and

The Pneumocystidomycetes are a class of ascomycete fungi. It includes the single order Pneumocystidales, which contains the single monotypic family Pneumocystidaceae, which in turn contains the genus Pneumocystis, causative agent of Pneumocystis pneumonia.

Sordariomycetidae is a subclass of sac fungi. Generally, species within the Sordariomycetidae subclass have light-dark coloured perithecia (flask shaped structures opening by a pore). The asci are non-amyloid, or lack apical rings. True paraphyses are normally present in most species. Three new genera were created within the Sordariomycetidae subclass based on morphological and molecular data (SSU and LSU nrDNA) to hold five ascomycete fungi species collected from submerged woody debris in freshwater habitats from Costa Rica. In 2015, after a study that found several genera of fungi taxa were

The Patellariaceae are a family of sac fungi. It is the only representative of the order Patellariales. According to a 2008 estimate, the family contains 15 genera and 38 species.

Neolecta is a genus of ascomycetous fungi. The species share the English designation "Earth tongues" along with some better-known fungi (e.g. Geoglossum, Microglossum) with a similar general form, but in fact they are only distantly related. Neolecta is the only genus belonging to the family Neolectaceae, which is the only family belonging to the order Neolectales. Neolectales, in turn, is the only order belonging to the class Neolectomycetes, which belongs to the subdivision Taphrinomycotina of the Ascomycota.

Lahmia is a genus of fungi in the phylum Ascomycota, or sac fungi. It is the only genus in the family Lahmiaceae and the order Lahmiales. The genus name of Lahmia is in honour of Johann Gottlieb Franz-Xaver Lahm (1811-1888), who was a German clergyman and botanist (Lichenology and Mycology). The genus of Lahmia was circumscribed by Gustav Wilhelm Koerber in Parerga Lichenol on page 281 in 1861.

Amarenomyces is a genus of fungi in the family Phaeosphaeriaceae. A monotypic genus, it contains the single species Amarenomyces dactylidis Mapook, Camporesi & K.D. Hyde (2017) A former species A. ammophilae (Lasch) O.E. Erikss. (1981) is now Amarenographium metableticum (still in the same Phaeosphaeriaceae family). The associated anamorph is the genus Amarenographium.

Meliolales is a fungal order in the class Sordariomycetes. Meliolales, also known as black mildews, are obligate parasitic ascomycetous fungi that are found in the tropics and subtropics on leaves, twigs, and sometimes fruit of vascular plants. As parasites, they are frequently parasitized by other fungi, known as hyperparasites.
