Notes – Didymosphaeria is the type genus of Didymosphaeriaceae which was established by Fuckel (1870) to accommodate three species with two-celled ascospores. Didymosphaeria is typified by D. futilis (Berkeley & Broome 1852, Zhang et al. 2012b; Hyde et al. 2013). Species of Didymosphaeria are characterized in having a peridium consisting of flattened or irregular cells or completely hyphae, a hamathecium consisting of narrow, trabeculate paraphysoids or paraphyses, richly anastomosing above the asci, and brown, thin, distoseptate ascospores (Zhang et al. 2012b). Asexual morphs of Didymosphaeria were reported as coelomycetous, like Dendrophoma sp. or Fusicladiella species (Sivanesan 1984, Zhang et al. 2012b). Despite having 195 morphological species in Species Fungorum (2020), few species have molecular data in GenBank, thus, more collections and sequence data are needed.
