Index Fungorum number: IF 943; Facesoffungi number: FoF 00220, 1 morphological species (Species Fungorum 2021), 0 species with molecular data.
Fungicolous associated with black areas of fungi on leaves. Sexual morph: Ascomata superficial, solitary or gregarious, globose-subglobose, membranous, white to pale yellow, covered by apically branched setae. Peridium comprising whitish yellow cells of textura angularis. Hamathecium comprising filiform, septate, branched, hyaline pseudoparaphyses, developing over asci. Asci 8-spored, bitunicate, elongate-clavate, cylindrical, short pedicellate, apically thickened, without an obvious ocular chamber. Ascospores fasciculate, filiform, tapering narrowly towards lower end, with several septa, hyaline. Asexual morph: Unknown (Adapted from Boonmee et al. 2014).
Type species: Chaetocrea parasitica Syd.
Notes: Chaetocrea was introduced by Sydow (1927) with C. parasitica as type species. Chaetocrea was previously placed in Hypocreaceae based on the bright-coloured ascomata. C. parasitica is fungicolous and grows on blackened areas of Cyclostomella disciformis which parasitized leaves of Nectandra sanguine (Lauraceae). Rossman et al. (1999) transferred Chaetocrea to Tubeufiaceae based on its bitunicate asci, pseudoparaphyses and long ascospores. C. parasitica is unique in having branching, pale yellow setae which is atypical of Tubeufiaceae. Hence, Boonmee et al. (2014) referred Chaetocrea as a member of Dothideomycetes genera incertae sedis.
