Fuckel (1870) described an aposphaeria- or phoma-like asexual morph of O. rugulosa by association on the natural host. Samuels (1980) synonymized four Ohleria species under O. modesta, transferred some species to Passeriniella, Sporormia or Preussia based on ascospore features, and accepted two additional species O. rugulosa and O. brasiliensis in the genus based on morphology of available type materials. Samuels (1980) described a hyphomycetous asexual morph in Monodictys for O. brasiliensis Starbäck. Jaklitsch & Voglmayr (2016) later suggested that O. brasiliensis may not be congeneric with Ohleria, and they also interpreted the Monodictys morph as a synanamorph as, for example, described by Grondona et al. (1997).

There are only two strains of the type species, O. modesta available in GenBank. The lectotype of O. modesta was recently designated by Jaklitsch & Voglmayr (2016). Ten epithets are listed in Species Fungorum (2020), while one of them was transferred to Preussia.

Type species: Ohleria modesta Fuckel.

Other accepted species: Species Fungorum – search Ohleria.
