Quaedvlieg et al. (2013) initially proposed a new species, Cylindroseptoria pistaciae, to Cylindroseptoria due to pycnidial conidiomata instead of cupulate conidiomata. Later, Thambugala et al. (2014) revised and established a new genus Neocylindroseptoria to accommodate Neocylindroseptoria pistaciae (Cylindroseptoria pistaciae) based on phylogenetic analysis of a combined dataset of ITS, SSU, and LSU gene regions. Neocylindroseptoria is described by black, erumpent, pycnidial, globose, separate conidiomata, with a central ostiole; peridium of 3–6 layers of brown textura angularis; phialidic, monophialidic, or polyphialidic conidiogenous cells bearing hyaline, smooth, cylindrical, straight to curved, aseptate, subobtuse conidia; conidia apex subobtuse, base truncate, and guttulate (Crous et al. 2013, Quaedvlieg et al. 2013). Quaedvlieg et al. (2013) introduced the holotype Neocylindroseptoria pistaciae from symptomatic leaves of Pistacia lentiscus in Spain but without more useful information on pathogenicity. However, this genus was synonymous with Dothiora by Crous et al. (2018).

Type species: Neocylindroseptoria pistaciae (Quaedvl., Verkley, & Crous) Thambug. & K.D. Hyde

Current name: Dothiora pistaciae (Quaedvl., Verkley & Crous) Crous

Other accepted species: Species Fungorum – search Dothiora
