Classification: Coronophoraceae, 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 Quellkörper. Peridium usually 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 – Coronophora is typified by C. gregaria which has polysporous asci and hyaline, cylindrical, aseptate ascospores (Fuckel 1864, Saccardo 1882b). There are 27 species in this genus, two of which have available molecular data, C. gregaria and C. myricoides (Mugambi & Huhndorf 2010, Hyde et al. 2016, Index Fungorum 2021). The characteristics of these two species are similar except for the ascospore size (Hyde et al. 2016). In this study, C. gregaria is sister to Scortechiniaceae (100%ML/1.00BY), whereas C. myricoides is sister to Fracchiaea (100%ML/1.00BY) in Nitschkiaceae. Thus, we transferred C. myricoides as Fracchiaea species (see notes for Fracchiaea myricoides).
