Crassochaeta Réblová, Mycotaxon 71: 46 (1999)
Index Fungorum number: IF28310; 2 morphological species (Species Fungorum 2020), 1 species with sequence data.
Type species – Crassochaeta nigrita (Sacc.) Réblová
Notes – Crassochaeta nigrita is characterized by tuberculate ascomata surrounded by needle-shaped setae, cylindrical asci and subglobose to ellipsoid, versicoloured ascospores. The asexual morph was reported as arthrinium-like Réblová (1999d). The phylogeny based on the LSU sequence data of C. nigrita was provided by Huhndorf et al. (2004a) and reveals a close relationship of Crassochaeta to Chaetosphaerella within Chaetosphaerellaceae.
