Based on phylogenetic analyses of combined LSU, SSU, ITS and tef1-α sequence data, Liu et al. (2019) introduced Pleopunctum with the type species P. ellipsoideum and P. pseudoellipsoideum in the family Phaeoseptaceae (Pleosporales, Dothideomycetes). Subsequently, seven other Pleopunctum species were described in China and Thailand (Phukhamsakda et al. 2020Boonmee et al. 2021Senwanna et al. 2021Wanasinghe et al. 2022Xu et al. 2023). Pleopunctum is a saprobic genus in terrestrial habitats. The sexual morph of Pleopunctum has not been reported. The asexual state is characterized by macronematous, mononematous, short conidiophores, monoblastic, integrated conidiogenous cells and oval to ellipsoidal, brown, muriform conidia often with a hyaline, globose to ellipsoidal basal cell (Liu et al. 2019Phukhamsakda et al. 2020Boonmee et al. 2021Senwanna et al. 2021Wanasinghe et al. 2022Xu et al. 2023). Hyaline phragmosporous or dictyosporous conidia has been reported in this genus (Phukhamsakda et al. 2020Senwanna et al. 2021Wanasinghe et al. 2022).
