Type species – Neocylindroseptoria pistaciae (Quaedvl., Verkley & Crous) Thambug. & K.D. Hyde, in Thambugala et al., Fungal Diversity 68: 125 (2014).

≡ Cylindroseptoria pistaciae Quaedvl., Verkley & Crous, Stud. Mycol. 75: 359 (2013).

Notes – Cylindroseptoria was introduced with two species, C. ceratoniae and C. pistaciae. The asexual morph of C. pistaciae is characterized by pycnidial, black, erumpent, conidiomata with a central ostiole, and phialidic conidiogenous cells which line the inner cavity. Conidia are aseptate, cylindrical, rarely slightly curved and guttulate. The sexual morph is undetermined (Quaedvlieg et al. 2013). The genus was typified by C. ceratoniae. Thambugala et al. (2014a) recognized C. ceratoniae as a separate linage from C. pistaciae in Dothideaceae based on their phylogenetic analysis. Neocylindroseptoria is therefore introduced to accommodate Cylindroseptoria pistaciae. Subsequently, Crous et al. (2018a) transferred N. pistaciae to Dothiora and introduced Dothiora pistaciae based on their phylogenetic analysis that consisted of only a few LSU sequence data of Dothideaceae. Nevertheless, in the present phylogenetic analysis based on combined ITS, LSU and SSU dataset (Fig. 27) N. pistaciae formed a well-supported, distinct clade basal to Dothideaceae (96 % MLBS, 1.00 PP) with Dothiora corymbiae which was introduced by Crous et al. (2018a). Therefore, we suggest Neocylindroseptoria should be kept as a separate genus in Dothideaceae and we introduce N. corymbiae for D. corymbiae.
