Notes – Exserohilum was established by Leonard & Suggs (1974) to accommodate species which were previously classified in Bipolaris whereby the conidial hilum was distinctly protuberant. A new genus Setosphaeria was also introduced to place the sexual morphs of Exserohilum which is distinct from Keissleriella based on the lack of clypeus, lysigenous development of the ostiole, occurrence of setae on the perithecial wall, the absence of periphyses in the ostiole and the hyphomycetous conidial states. The asexual name Exserohilum has priority over Keissleriella (morphology see Ariyawansa et al. 2015, Wijayawardene et al. 2018).
