Notes – Neokalmusia was established to accommodate two bambusicolous taxa, N. brevispora and N. scabrispora previously referred to Kalmusia (Zhang et al. 2009b, Ariyawansa et al. 2014d). Subsequent phylogenetic studies have shown that these two species belong to Neokalmusia in Didymosphaeriaceae (Hyde et al. 2013, Ariyawansa et al. 2014b). Neokalmusia is characterized by immersed, subglobose to oblong ascomata with several perithecia in a row, a clypeus-like structure composed of thin-walled cells and verrucose ascospores (Ariyawansa et al. 2014d). There are six Neokalmusia epithets in Species Fungorum (2020), N. arundinis, N. brevispora, N. didymospora, N kunmingensis, N. scabrispora and N. thailandica.
