Dothideomycetes

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.

Dothideomycetidae is a fungal subclass in the class Dothideomycetes The cavities of the sexual structures do not have vertical cells (paraphyses, pseudoparaphyses or paraphysoids) growing between the sac-like cells bearing the sexual spores (asci).

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 canno

The Phaeotrichaceae are a family of fungi previously considered to be in the order Pleosporales, but now excluded. Taxa have a widespread distribution and are saprobic, on herbivore dung.

The Botryosphaeriales are an order of sac fungi (Ascomycetes), placed under class Dothideomycetes. Some species are parasites, causing leaf spot, plant rot, die-back or cankers, but they can also be saprophytes or endophytes. They occur world-wide on many hosts. For example, in China, infections related to Botryosphaeriales have been recorded on numerous hosts such as grapes, Caragana arborescens,Cercis chinensis, Eucalyptus, Chinese hackberry, blueberry, forest trees, and various other woody hosts.

Melaspileaceae is a family of lichenised and saprobic fungi in the class Dothideomycetes, order Eremithallales. A 2015 phylogenetic study narrowed the family to two genera, Melaspilea and Encephalographa, and showed that Eremithallales, which had been proposed in 2008, belongs within the Dothideomycetes, and treated Eremithallaceae as a synonym of Melaspileaceae. Many names historically kept in Melaspileaceae but having lichenicolous or saprobic life histories are part of the order Asterinales and belong in segregate genera such as Melaspileella, Melaspileopsis, Stictographa, Karschia, Buellie

Teratosphaeriaceae is a family of fungi in the order Mycosphaerellales.

The Lichenotheliaceae are a family of fungi, and the only family in the order Lichenotheliales, which is in the class Dothideomycetes. The family contains three genera.

Hysterographium is a genus of fungi in the class Dothideomycetes. It was circumscribed by Czech mycologist August Carl Joseph Corda in 1842.

Melaspilea is a genus of fungi in the family Melaspileaceae. The genus includes both lichen-forming species that grow on tree bark and lichenicolous species that parasitise other lichens. Originally, Melaspilea encompassed a broad and diverse group of species, but a 2015 molecular study narrowed its circumscription, showing that many species historically placed in the genus actually belonged to unrelated lineages. In its current sense, Melaspilea belongs to the family Melaspileaceae and order Eremithallales within Dothideomycetes and is characterised by dark fruiting bodies with single-septum

Asterinales is an order of fungi in the class Dothideomycetes. It contains ten families according to the 2021 work "Outline of Fungi and fungus-like taxa", each of which is listed with the number of genera it contains:

Endococcus is a genus of lichenicolous (lichen-dwelling) in the family Lichenotheliaceae. It has 44 species. The genus was circumscribed by the Finnish botanist William Nylander in 1855. Although at least one source places the genus in the Verrucariaceae, a 2016 study of the type species, Endococcus rugulosus, determined that it should instead be placed in the family Lichenotheliaceae of the order Dothideales; this classification echoes a placement proposed in 1979 by David Hawksworth.

Leptosphaerulina 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 it was placed within the Didymellaceae family in the Pleosporales order. The genus was first described by Australian plant pathologist Daniel McAlpine in 1902.

Hemigrapha is a genus of fungi in the family Hemigraphaceae. The genus was established in 1975 and currently includes nine recognised species. These fungi are parasites that grow on other lichens, producing distinctive flat, star-shaped or elongated black fruiting bodies on their host's surface.

Patellaria is a genus of fungi in the family Patellariaceae. The genus was circumscribed in 1822 by mycologist Elias Magnus Fries with Patellaria atrata assigned as the type species.

Buelliella is a genus of lichenicolous (lichen-dwelling) fungi in the family Stictographaceae. It comprises 13 thirteen species. The genus was established in 1935 by the American lichenologist Bruce Fink, who originally included seven species. These fungi are parasites that live on other lichens, producing small disc-shaped fruiting bodies that start buried in their host and later emerge at the surface.
