Neocylindroseptoria K. M. Thambugala & K. D. Hyde, gen. nov., Index Fungorum number: IF 550730.
Etymology: The generic epithet, neo (Lat., new), refers to the similarity to Cylindroseptoria.
Type species: Neocylindroseptoria pistaciae (Quaedvlieg, Verkley & Crous) K. M. Thambugala & K. D. Hyde, com. nov., Index Fungorum number: IF550731
≡ Cylindroseptoria pistaciae Quaedvlieg, Verkley & Crous, Stud. Mycol. 75: 359 (2013)
Asexual state: Conidiomata pycnidial, globose, black, erumpent, separate, with black crusty outer layer of cells, with central ostiole; wall of 3−6 layers of brown cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells phialidic (mostly monophialidic, but a few observed to also be polyphialidic), lining the inner cavity, hyaline, smooth, ampulliform, proliferating percurrently (inconspicuous) or with periclinal thickening at apex (also occurring as solitary loci on superficial hyphae surrounding pycnidia). Conidia cylindrical, mostly straight, rarely slightly curved, hyaline, smooth-walled, apex subobtuse, base truncate, guttulate, aseptate (Quaedvlieg et al. 2013). Sexual state: Unknown.
Notes: Cylindroseptoria pistaciae was introduced by Quaedvlieg et al. (2013) and tentatively placed in Cylindroseptoria as it has pycnidial rather than cupulate conidiomata. Cylindroseptoria pistaciae separates from C. ceratoniae and formed a strong clade in Dothideaceae with 98/100 % bootstrap support. Therefore, we introduce Neocylindroseptoria to accommodate C. pistaciae.
