The Hypocreales are an order of fungi within the class Sordariomycetes. In 2008, it was estimated that it contained some 237 genera, and 2647 species in seven families. Since then, a considerable number of further taxa have been identified, including an additional family, the Stachybotryaceae. Wijayawardene et al. in 2020 added more families and genera to the order. According to the Catalog of Life, As of April 2021 the Hypocreales contains 6 families, 137 genera, and 1411 species. Hyde et al. (2020a) listed 14 families under Hypocreales, while, Wijayawardene et al. (2022) accepted 15 families in the order, where Cylindriaceae was additionally added. Earlier, Hyde et al. (2020a) had placed Cylindriaceae in class Xylariomycetidae. Samarakoon et al. (2022) agreed. Hence, Cylindriaceae should have been excluded from Hypocreales and placed in Xylariomycetidae. Xiao et al. (2022) recently introduced a new family Polycephalomycetaceae to Hypocreales.
Nectria is a genus of Ascomycete fungi. They are most often encountered as saprophytes on decaying wood but some species can also occur as parasites of trees, especially fruit trees and a number of other hardwood trees. Some species are significant pests causing diseases such as apple canker, Nectria twig blight, and coral spot in orchards.
The Nectriaceae comprise a family of fungi in the order Hypocreales. It was circumscribed by brothers Charles and Louis René Tulasne in 1865. In 2020, an Outline of fungi was produced and listed 70 genera and about 1,336 species.
Hypocreomycetidae is a subclass of sac fungi.
The Melanommataceae are a family of fungi in the order Pleosporales. Taxa are widespread in temperate and subtropical regions, and are saprobic on wood and bark.
The Didymosphaeriaceae are a family of fungi in the order Pleosporales. The family was erected by Anders Munk in 1953.
The Odontotremataceae are a family of fungi in the monotypic order of Odontotrematales. Species of this family have a widespread distribution, but are especially known from northern temperate areas.
The Halosphaeriaceae are a family of fungi in the Sordariomycetes class, subclass Hypocreomycetidae. Halosphaeriaceae is the family with the largest number of marine fungi with a few species are from freshwater and terrestrial habitats.
Phomatospora is a genus of fungi within the class Sordariomycetes, and since 2016, in the family Phomatosporaceae and order Phomatosporales. They are found in terrestrial, freshwater and marine habitats, across the world except Russia and Canada.
Hydropisphaera is a genus of fungi in the class Sordariomycetes. It consisted of 18 species in 2008, and 32 species in 2023.
Lasionectria is a genus of fungi in the class Sordariomycetes. It consisted of six species in 2008, and 16 in 2023.
Protocreopsis is a genus of fungi in the class Sordariomycetes. It consisted of nine species in 2008, and up to 11 species in 2023.
Albonectria is a genus of ascomycete fungi in the family Nectriaceae.
Corallomycetella is a genus of ascomycete fungi in the family Nectriaceae. Species of Corallomycetella are tropical, and are characterized by the formation of brightly colored rhizomorphs of their rhizostilbella-like asexual morphs. These fungi causes a number of plant diseases including 'violet root rot' of Theobroma cacao, root rot of Carica papaya, and 'stinking root disease' of several tropical woody plants. Two species of Corallomycetella are recognized: Corallomycetella elegans C. Herrera & P. Chaverri and Corallomycetella repens Rossman & Samuels. Corallomycetella jatrophae is now classified under Corallonectria.
Cosmospora is a genus of ascomycete fungi in the family Nectriaceae. The genus, as circumscribed by Rossman et al. (1998), included all the nectrioid species with small, reddish, non-ornamented sexual fruiting bodies that collapse laterally when dry. However, the genus was shown to be polyphyletic, and the majority of species were re-classified into revived or recently established genera that are monophyletic. Cosmosporasensu Rossman housed members of the following genera: Chaetopsina, Cylindrocladiella, Fusicolla, Macroconia, Mariannaea, Microcera, Pseudocosmospora, Stylonectria, and Volutella. Cosmospora was restricted to species having acremonium-like asexual morphs that grow on polypores and xylariaceous fungi by Gräfenhan in 2011. About 20 species are accepted in the genus.
Neonectria is a genus of fungi in the family Nectriaceae.
The Nitschkiaceae are a family of fungi in the Ascomycota, order Coronophorales. Species in the family are mostly saprobic on wood, although some grow on lichens.
Corallonectria is a genus of ascomycete fungi in the family Nectriaceae. Species of Corallonectria are Neotropical. These fungi are characterized by the formation of brightly colored rhizomorphs and of copulated synnematous fusarium-like asexual morphs in culture. The asexual morph in nature has been rarely observed. The sexual fruiting bodies are furfuraceous and usually seated at the base of a reddish synnemata. It is a monotypic genus containing the sole species Corallonectria jatrophae. This species was formerly classified under Corallomycetella.
Clonostachys is a genus of fungi in the order Hypocreales and family Bionectriaceae.
Volutella is a genus of fungi belonging to the family Nectriaceae.
