The Chaetosphaeriaceae are a group of saprobic fungi growing on decaying woody and herbaceous plant material (Cannon & Kirk 2007).

Characters (from Cannon & Kirk 2007): Stroma absent or restricted to a thin sometimes subiculate crust. Ascomata perithecial, superficial, often aggregated, black, ± globose to conical, usually rather thin-walled but often carbonaceous, glabrous or setose, the ostiole papillate, periphysate. Interascal tissue of copious persistent true paraphyses. Asci cylindrical, persistent, thin-walled, not fissitunicate, with a well-developed refractive J- apical ring. Ascospores ellipsoidal to fusiform, transversely septate, sometimes fragmenting at the septa, hyaline or brown. Anamorphs hyphomycetous, varied, with pigmented conidiophores and percurrently proliferating conidiogenous cells often with widely flared collarettes, conidia very varied in form but mostly small and hyaline.
