 Based on phylogenies of five-loci of ITS, LSU, RPB2, TEF-1α and TUB sequences, Quaedvlieg et al. (2014) introduced Teratosphaericola as a monotypic genus within Teratosphaeriaceae, Mycosphaerellales in Dothideomycetes with type species Teratosphaericola pseudoafricana. Teratosphaericola pseudoafricana was first described as Mycosphaerella pseudoafricana by Crous et al. (2006) (≡ Teratosphaeria pseudoafricana (Crous et al. 2007)). Morphologically, Teratosphaericola is similar to Teratosphaeria and can only be distinguished based on its DNA phylogeny (Quaedvlieg et al. 2014). The member of Teratosphaericola can be found as foliicolous or plant pathogenic and characterized by having ascomata pseudothecial; ostiole apical, central; wall of 2–3 cell layers of medium brown textura angularis;   fasciculate asci, aparaphysate, bitunicate, subsessile, narrowly ellipsoid to subcylindrical, 8-spored; hyaline to pale brown ascospores, tri- to multiseriate, overlapping, thin-walled, fusoid-ellipsoidal with subobtuse ends, medianly 1-septate while, spermatia is hyaline, smooth, rod-shaped with rounded ends. The second species, T. leucadendri, was introduced from the leaves of Leucadendron sp. (Crous et al. 2021), and the third species, Teratosphaericola ellenclarkiae, was introduced from Grevillea decora subsp. (Tan & Shivas 2022).
