Endophytic, saprobic or pathogenic on host plants. The sexual morph is undetermined. The asexual morph is characterized by the pycnidial conidiomata, which are dark brown, separate, becoming integrated, globose, and erumpent. The ostiole is located in the  centre. The pycnidial wall is composed of textura angularis with brown-walled cells. Conidiophores are subcylindrical, septate, straight to curved, unbranched or branched at the base, smooth-walled and hyaline. Conidiogenous cells are phialidic, proliferating percurrently, terminate, scattered, subcylindrical, straight to geniculate, smooth-walled and hyaline. Conidia are subcylindrical, straight to irregularly curved, apex obtuse, base truncate to bluntly rounded, with or without guttules, hyaline when immature, becoming 1-septate, with prominently striate covering the length of the conidium, golden-brown when mature, becoming dark brown after discharge (Crous et al. 2015, 2016; Wijayawardene et al. 2016).

Notes: Neosulcatispora was introduced by Crous et al. (2015) based on N. agaves as the type species, which was isolated from on leaves of Agave vera-cruz. The second species, Neosulcatispora strelitziae was isolated from the leaves spot of Strelitzia nicolai by Crous et al. (2016). Currently, there are only two species (N. agaves and N. strelitziae) listed under Neosulcatispora in Species Fungorum (August 2024) and a total of 16 ITS, LSU, and tub2 sequences available in GenBank (August 2024). The updated taxonomic treatment of this genus is Phaeosphaeriaceae, in Pleosporales (Dothideomycetes) (Wijayawardene et al. 2022)

Type species: Neosulcatispora agaves Crous & M.J. Wingf., in Crous et al., Persoonia 35: 283 (2015).

Other accepted species: Species Fungorum – search Neosulcatispora.
