Winter (1885) introduced the family with Amphisphaeria as the type genus. Amphisphaeriaceous taxa are mainly saprobes on dead plant material in terrestrial, aquatic and marine habitats (Senanayake et al. 2015, Samarakoon et al. 2019, Hyde et al. 2020c). Sexual morph is characterized by pseudostromata on host plant consisting 8-spored, unitunicate asci with J+ or J-, apical ring, brown, ellipsoidal to fusiform, 1-septate ascospores (Hyde et al. 2020c). Asexual morph is coelomycetous with dichotomously branched conidiophores bearing hyaline, 1-celled conidia  (Hyde et al. 2020c). Samarakoon et al. (2020) synonymized Lepteutypa under Amphisphaeria based on holomorphic morphology and multigene phylogeny and thereby Amphisphaeria is the only genus in Amphisphaeriaceae.

Type genus: Amphisphaeria Ces. & De Not., Comm. Soc. crittog. Ital. 1(fasc. 4): 223 (1863).
