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.
Discomycetes is a former taxonomic class of Ascomycete fungi which contains all of the cup, sponge and brain fungi, and some club-like fungi. It includes typical cup fungi like the scarlet elf cup and the orange peel fungus, and fungi with fruiting bodies of more unusual shape, such as morels, truffles and the swamp beacon. New taxonomic and molecular data fail to support the monophyly of the Discomycetes.
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.
The Leotiomycetes are a class of ascomycete fungi. Many of them cause serious plant diseases.
The order Sordariales is one of the most diverse taxonomic groups within the Sordariomycetes.
Helotiales is an order of the class Leotiomycetes within the division Ascomycota. The taxonomy within Helotiales has been debated. It has expanded significantly as genomic techniques for taxonomical identification have become more commonly used. As of February 2020, the order is estimated to contain 30 accepted families, 519 genera, and 6266 species.
The Pezizales are an order of the subphylum Pezizomycotina within the phylum Ascomycota. The order contains 16 families, 199 genera, and 1683 species. It contains a number of species of economic importance, such as morels, the black and white truffles, and the desert truffles. The Pezizales can be saprobic, mycorrhizal, or parasitic on plants. Species grow on soil, wood, leaves and dung. Soil-inhabiting species often fruit in habitats with a high pH and low content of organic matter, including disturbed ground. Most species occur in temperate regions or at high elevation. Several members of the Sarcoscyphaceae and Sarcosomataceae are common in tropical regions.
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci of the Lecanoromycetes most often release spores by rostrate dehiscence.
The Pleosporales is the largest order in the fungal class Dothideomycetes. By a 2008 estimate, it contained 23 families, 332 genera and more than 4700 species. The majority of species are saprobes on decaying plant material in fresh water, marine, or terrestrial environments, but several species are also associated with living plants as parasites, epiphytes or endophytes. The best studied species cause plant diseases on important agricultural crops e.g. Cochliobolus heterostrophus, causing southern corn leaf blight on maize, Phaeosphaeria nodorum causing glume blotch on wheat and Leptosphaeria maculans causing a stem canker on cabbage crops (Brassica). Some species of Pleosporales occur on animal dung, and a small number occur as lichens and rock-inhabiting fungi.
The Hysteriaceae are a taxonomic family of fungi and the only extant family of the order Hysteriales. Members of the Hysteriaceae are defined by the possession of a sexual structure called the hysterothecium, an elongated structure that opens by a longitudinal slit and releases sexually produced spores. The family is widely distributed, with many species found in temperate regions, and most are saprobic on wood and bark, although a few are parasitic on plants.
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.
The Arthoniales is the second largest order of mainly crustose lichens, but fruticose lichens are present as well. The order contains around 1500 species, while the largest order with lichenized fungi, the Lecanorales, contains more than 14000 species.
Geoglossaceae is a family of fungi in the order Geoglossales, class Geoglossomycetes. These fungi are broadly known as earth tongues. The ascocarps of most species in the family Geoglossaceae are terrestrial and are generally small, dark in color, and club-shaped with a height of 2–8 cm. The ascospores are typically light-brown to dark-brown and are often multiseptate. Other species of fungi have been known to parasitize ascocarps. The use of a compound microscope is needed for accurate identification.
Leotiomyceta represents all the filamentous ascomycete fungi (Pezizomycotina), excluding the classes Pezizomycetes and Orbiliomycetes. It is well supported in several studies comparing DNA sequences in fungi. It has originally been proposed as a superclass but later was proposed as a rankless taxon for any well supported group above class. Rankless taxa do not strictly follow the rules for taxonomic classifications in plants and fungi (ICBN) and therefore these names are informal, although they appear to reflect natural groups.
Paleopyrenomycites is a Devonian genus of fungus of uncertain phylogenetic affinity within the Pezizomycotina total group, known from the Rhynie chert.
Rhizocarpales are an order of lichen-forming fungi in the subclass Lecanoromycetidae of the class Lecanoromycetes. It has two families, Rhizocarpaceae and Sporastatiaceae, which contain mostly crustose lichens.
Conioscyphales is an order of freshwater and terrestrial fungi within the division Ascomycota. It is in the subclass Savoryellomycetidae and the class Sordariomycetes and the subdivision of Pezizomycotina.
Fuscosporellales is an order of fungi within the phylum of Ascomycota and in the class Sordariomycetes and subdivision of Pezizomycotina.
Pleurotheciaceae is a family of ascomycetous fungi within the monotypic order of Pleurotheciales in the subclass Savoryellomycetidae and within the class Sordariomycetes.
The Xylonomycetes are a class of fungi, which holds 2 orders of SymbiotaphrinalesBaral & E. Weber, and XylonalesGazis & P. Chaverri.
