Nodulosphaeria, was introduced by Rabenhorst (1858) and typified by N. hirta and was accommodated in Phaeosphaeriaceae by Barr (1987). The genus comprises endophytic, saprobic and pathogenic taxa which occur on a variety of hosts (Mapook et al. 2020; Chaiwan et al. 2019; Pasouvang et al. 2021). Nodulosphaeria taxa are principally characterised by ascomata with brown setae at the ostiole and three-to multi-septate ascospores with a swollen cell and often with terminal appendages (Shoemaker 1984; Mapook et al. 2016; Chaiwan et al. 2019). Molecular data for several Nodulosphaeria species listed in MycoBank (http:// www. mycob ank. org/, 07/2022) and Index Fungorum (http:// www. index fungo rum. org/ Names/ Names. asp, 07/2022) are unavailable. A reference specimen for the type species N. hirta was recently designated by Mapook et al. (2016), who also provided molecular data for the same.
