The monotypic genus Neosphaerellopsis was established to accommodate the type Neosphaerellopsis thailandica, which was isolated from rust sori on Bothriochloa bladhii from Thailand in its asexual morph (Trakunyingcharoen et al. 2014). Neosphaerellopsis mostly resembles Sphaerellopsis but differs in the ITS- and LSU-based phylogeny (Trakunyingcharoen et al. 2014). Neosphaerellopsis also resembles Tiarospora but, the latter has deeply immersed, stromatic pycnidia, percurrent proliferating conidiogenous cells, and broadly ellipsoidal conidia that turn brown at maturity (Nag Raj 1993). Neosphaerellopsis clustered between Parastagonospora and Sclerostagonospora in Phaeosphaeriaceae but, differs from both genera in having mucoid conidial appendages (Trakunyingcharoen et al. 2014).
Type species: Neosphaerellopsis thailandica Crous & Trakun.
Other accepted species: This genus is monotypic.
