Classification: Coronophorales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on wood, sometimes fungicolous. Sexual morph: Ascomata perithecial or without an external opening, solitary or gregarious, semi-immersed or erumpent or superficial, black, usually carbonaceous, globose to subglobose, sometimes with necks, tuberculate, collapsing or laterally collapsing when dry, glabrous or with hairs, with or lacking ostioles, usually with a central column of mucilaginous cells (Quellkörper). Peridium outer layer composed of carbonaceous, black tissue; inner layer composed of membranaceous, brown to hyaline cells of textura angularis to textura prismatica. Paraphyses absent or numerous, filiform, septate, evanescent. Asci numerous or rare, polysporous, unitunicate, clavate to cylindrical, long pedicellate, apex blunt or rounded, apical ring inconspicuous, evanescent. Ascospores crowded, numerous, hyaline, allantoid to cylindrical, sometimes curved, 0–1-septate, smooth-walled, mostly with guttules. Asexual morph: Undetermined (adapted from Fuckel 1864, Saccardo 1882a).

Notes – Coronophoraceae was introduced by von Höhnel (1907) to accommodate Cryptosphaerella and Coronophora, and it is characterized by polysporous asci and hyaline, allantoid ascospores. Subsequently, Cryptosphaerella was clarified as a genus in Scortechiniaceae based on phylogenetic result (Mugambi & Huhndorf 2010). Coronophora was placed as an independent clade in Coronophorales based on the sequences data of Cor. gregaria (Mugambi & Huhndorf 2010). Therefore, Coronophora is the only member in Coronophoraceae, and this genus is similar to Fracchiaea (Nitschkiaceae) and Pleurostoma (Pleurostomataceae, Calosphaeriales) in having black ascomata and clavate, polysporous asci (Petch 1916, Barr 1985, Mugambi & Huhndorf 2010, Maharachchikumbura et al. 2015, 2016, Hyde et al. 2020e). 

Type genus: Coronophora Fuckel.
