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

Colletotrichum orbiculare is a plant pathogen of melons and cucumber. It causes the disease anthracnose that can effect curcubits causing lesions on various parts of the plant. It can effect cucumbers, melon, squash, watermelon and pumpkin, especially when the weather is rainy, humid and warm. It can be transmitted by seed as well as soil and survive between crops. It is also spread by feeding cucumber beetles, splashing water, tools and workers. Efforts to control the fungus include the practice of rotating cucurbits out for a 2-year period, planting cultivars with resistance, burning

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. The order was originally defined in 2006 to have only one family, Botryosphaeriaceae, but new

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. Genera: Amniculicola Ying Zhang & K.D.Hyde Anguillospora Ingold, 1942 Murispora Y.Zhang bis, J.Fourn. & K.D.Hyde Neomassariosphaeria Zhang, Fourn. & Hyde, 2009 Pseudomassariosphaeria Phukhamsakda et al.

Togniniaceae is family of fungi in the order Togniniales.

Teratosphaeriaceae is a family of fungi in the order Mycosphaerellales.

The Davidiellaceae are a family of fungi in the Ascomycota, class Dothideomycetes. The family was defined in 2006 based on the results of molecular phylogenetic analysis of various Dothideomycetes species, and contains the genus Davidiella and six other genera.

Pleurostomataceae is a family of fungi in the order Calosphaeriales.

Mycovellosiella concors is a fungal plant pathogen infecting potatoes.

Tapesia yallundae is the causal agent for a variety of cereal and forage grass diseases. The anamorph of T. yallundae is the W-type strain of Pseudocercosporella herpotrichoides. The R-type strain of Pseudocercosporella herpotrichoides is now known as Tapesia acuformis.

The Stachybotryaceae are a family of fungi in the order Hypocreales; the genera it contains have been described as "hyper-diverse". The family was originally introduced by Crous et al. (2014) to accommodate three genera; Myrothecium, Peethamabra and Stachybotrys. It was revised by Lombard et al. (2016) based on morphological characters and multi-locus phylogenetic analysis. They accepted 33 genera in the family, including 21 new genera. Generally, the species in Stachybotryaceae are characterized by asexual morphs with mononematous to sporodochial to synnematous conidiomata, usually with

Rhinocladiella mackenziei is a deeply pigmented mold that is a common cause of human cerebral phaeohyphomycosis. Rhinocladiella mackenziei was believed to be endemic solely to the Middle East, due to the first cases of infection being limited to the region. However, cases of R. mackenziei infection are increasingly reported from regions outside the Middle East. This pathogen is unique in that the majority of cases have been reported from immunologically normal people.

The Pyriculariaceae are a family of ascomycete fungi in the order Magnaporthales. It was introduced by S. Klaubauf, M.H. Lebrun & P.W. Crous in 2014.

Neofusicoccum is a genus of fungi in the family Botryosphaeriaceae.

The Lentitheciaceae are a family of fungi in the order of Pleosporales. They are found world-wide (within China, Egypt, Hungary, Italy, Japan, Russia, Saudi, Thailand, UK and Uzbekistan,) with the greatest contributions found in Europe and Australia. In a phylogenetic study of Lophiostoma and Massarina species, Lentithecium was proposed in 2009 based on Lophiostoma fluvitale now called Lentithecium fluviatile (Aptroot & Van Ryck.) K.D.Hyde, J.Fourn. & Ying Zhang. Lentitheciaceae is a well supported clade. Lentitheciaceous taxa are saprobic (living on dead tissue) on herbaceous and woody

Phaeomoniella chlamydospora is a fungus species of mitosporic ascomycota in the genus Phaeomoniella. Phaeomoniella chlamydospora and Phaeoacremonium aleophilum are associated with esca in mature grapevines, decline in young vines (Petri disease) and black goo decline, three types of grapevine trunk disease.

Phaeomoniella is a genus of hyphomycete fungi in the family Celotheliaceae. The genus was circumscribed by Pedro Crous and Walter Gams in 2000 to contain the type species, P. chlamydospora, the causal agent of Petro grapevine decline, a disesase in the esca disease complex. Phaeomoniella is similar to Phaeoacremonium, differing in cultural characteristics, and in the morphology of the conidiophores and conidia. The family Phaeomoniellaceae was proposed by Paul Kirk in 2015, using a reference to the description of the order Phaeomoniellales, circumscribed earlier that year. However, because

Phaeoacremonium aleophilum is a fungus species in the genus Phaeoacremonium. It is associated with Phaeomoniella chlamydospora in esca in mature grapevines and decline in young vines (Petri disease), two types of grapevine trunk disease. Togninia minima is the teleomorph (the sexual reproductive stage) of P. aleophilum.

Phaeoacremonium is a fungus genus associated with wilt and decline diseases of woody hosts and human infections. Togninia is the teleomorph (the sexual reproductive stage) of Phaeoacremonium.
