Phaeothecaceae Darveaux, in Crous et al., Persoonia 41: 393 (2018).
MycoBank number: MB 828184; Index Fungorum number: IF 828184; Facesoffungi number: FoF 07639, 5 species.
Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Mycelium hyaline to brown, smooth-walled, septate, branched hyphae that swell up in terminal or intercalary cells, and develop numerous endoconidia. Conidiophores reduced to conidiogenous cells. Conidiogenous cells integrated, brown, expanding as endoconidia, finally rupturing and releasing mature endoconidia. Endoconidia globose to obovoid, brown when seen en mass, pale brown when viewed individually, aseptate to muriformly septate, thin- to thick-walled, smooth. Secondary conidia none (adapted from Crous et al. 2018a).
Notes – The family was established by Crous et al. (2018a) to accommodate a single genus Phaeotheca based on phylogenetic placement of P. fissurella and P. shathenatiana.
