Classification: Incertae sedis, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on stems or wood or coprophilous. Sexual morph: Ascomata perithecial, scattered, superficial to semi-immersed, erumpent through bark of host, pyriform to subglobose, black, glabrous or hairy, ostiolate, with papilla, periphysate. Peridium membranaceous. Paraphyses filiform. Asci 8-spored, unitunicate, cylindrical to clavate, pedicellate, with J- apical ring. Ascospores broadly clavate to obpyriform, aseptate, hyaline to brown, smooth-walled or verrucose, with conical gelatinous appendage at the apex. Asexual morph: Undetermined (adapted from Fuckel 1870; Lundqvist 1972).
Notes: Fuckel (1870) established Camptosphaeria which is typified by Cam. sulphurea. Lundqvist (1972) reduced this genus as a subgenus of Cercophora because the cylindrical to broadly fusiform ascospores are similar to Cercophora and Podospora. Krug and Jeng (1977) re-defined Camptosphaeria as a genus which has pod-like ascospores with conical gelatinous appendages and suggested that its ascospores are similar to Bombardia (Bombardiaceae) and Lasiosphaeria (Lasiosphaeriaceae). Thus, we place the genus in Sordariales genera incertae sedis pending molecular data.
Type species: Camptosphaeria sulphurea Fuckel, Jb. nassau. Ver. Naturk. 23-24: 140 (1870) [1869-70].
