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.
Stagonospora is a genus of fungi clustering in the Phaeosphaeriaceae (Quaedvlieg). Several of the species in this genus are plant pathogens.
Dothideomycetidae is a subclass of Dothideomycetes consisting of three orders: Dothideales, Myriangiales and Capnodiales. The cavities of the sexual structures do not have vertical cells growing between the sac-like cells bearing the sexual spores (asci).
Capnodiales is a diverse order of Dothideomycetes, initially based on the family Capnodiaceae, also known as sooty mold fungi. Sooty molds grow as epiphytes, forming masses of black cells on plant leaves and are often associated with the honeydew secreted by insects feeding on plant sap. This diverse order has been expanded by the addition of several families formerly thought unrelated and now also includes saprobes, endophytes, plant pathogens, lichens and rock-inhabiting fungi. The new additions include the genus Mycosphaerella containing the causal agents of several economically important crop and tree diseases. A small number of these fungi are also able to parasitise humans and animals, including species able to colonise human hair shafts.
Pleosporomycetidae is a subclass of Dothideomycetes consisting of four orders: Pleosporales, Hysteriales, Mytilinidiales, and Jahnulales. One of its defining features is the presence of pseudoparaphyses. These are sterile cells extending down from the upper portion of the cavity inside sexual structures containing the sac-like asci with sexually produced spores (ascospores). Pseudoparaphyses are initially attached at both their ends, but sometimes the upper part may become free. Some orders and families where these cells are present remain outside the subclass since DNA-based phylogenies cannot place them with confidence. However, they could conceivably be included within Pleosporomycetidae in future.
Pleosporaceae is a family of sac fungi. They are pathogenic to humans or saprobic on woody and dead herbaceous stems or leaves.
Phoma is a genus of common coelomycetous soil fungi. It contains many plant pathogenic species.
The Lophiostomataceae are a family of fungi in the order Pleosporales. Taxa have a widespread distribution, especially in temperate regions, and are saprobic or necrotrophic on herbaceous and woody stems.
The Massarinaceae are a family of fungi in the order Pleosporales. Although taxa have a cosmopolitan distribution, they are better-known in temperate regions. They are thought to be saprobic in wood and bark; some species are weak pathogens.
Lophiostoma is a genus of ascomycetous fungi in the family Lophiostomataceae.
Salsuginea is a genus of fungi in the class Dothideomycetes. The relationship of this taxon to other taxa within the class was unknown in 2007. Until Kevin D. Hyde & Tibpromma, 2013 introduced family Salsugineaceae within the order of Pleosporales.
Black yeasts, sometimes also black fungi, dematiaceous fungi, microcolonial fungi or meristematic fungi is a diverse group of slow-growing microfungi which reproduce mostly asexually. Only few genera reproduce by budding cells, while in others hyphal or meristematic (isodiametric) reproduction is preponderant. Black yeasts share some distinctive characteristics, in particular a dark colouration (melanisation) of their cell wall. Morphological plasticity, incrustation of the cell wall with melanins and presence of other protective substances like carotenoids and mycosporines represent passive physiological adaptations which enable black fungi to be highly resistant against environmental stresses. The term "polyextremotolerance" has been introduced to describe this phenotype, an example of which is the species Aureobasidium pullulans. Presence of 1,8-dihydroxynaphthalene melanin in the cell wall confers to the microfungi their characteristic olivaceous to dark brown/black colour.
The Didymellaceae are a family of fungi in the order Pleosporales. They have a world-wide distribution.
Amniculicolaceae is a family of fungi belonging to the order Pleosporales. First described in 2009 by Y. Zhang ter, C.L. Schoch, J. Fournier, Crous & K.D. Hyde, the type genus is Amniculicola.
Camarosporium is a genus of fungi belonging to the order Pleosporales, and originally placed in family Coniothyriaceae. It was then placed in the family Camarosporiaceae Wanas., Wijayaw., K.D. Hyde & Crous, 2017 with another genus Camarosporomyces. This has been accepted by Wijayawardene et al. 2020.
The Lentitheciaceae are a family of fungi in the order of Pleosporales. They are found world-wide with the greatest contributions found in Europe and Australia.
The Trematosphaeriaceae are a family of fungi in the order of Pleosporales. They are found world-wide with the greatest contributions found in Europe and Australia. It includes taxa that are found in the marine environment, such as Falciformispora lignatis which can be found in freshwater and marine habitats. Most are saprobic species.
Xenodevriesia strelitziicola is a pathogenic ascomycete fungus in the class Dothideomycetes that infects the South African plant Strelitzia. It is the only species of the monotypic genus Xenodevriesia and family Xenodevriesiaceae.
Coniothyriaceae is a family of ascomycetous marine based fungi within the order of Pleosporales in the subclass Pleosporomycetidae and within the class Dothideomycetes. They are pathogenic or they can be saprobic on dead branches. They are generally a anamorphic species.
Neocamarosporium is a genus of ascomycete fungi, as accepted by Wijayawardene et al. 2020. The species are typically halotolerant, being commonly found in saline environments like in saline water, hypersaline soils and especially in association with halophytes.
