Neoseptoria Quaedvl., Verkley & Crous, Stud. Mycol. 75: 352 (2013)
Index Fungorum number: IF 804421; Facesoffungi number: FoF 08526, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.
Foliicolous. Sexual morph: Unknown. Asexual morph: Conidiomata black, immersed, subepidermal, pycnidial, subglobose with central ostiole, exuding creamy conidial mass; wall of 2–3 layers of brown textura angularis. Conidiophores 0–2-septate, sub cylindrical, hyaline to pale brown at base, smooth, straight to geniculate-sinuous. Conidiogenous cells phialidic, hyaline, smooth, aggregated, lining the inner cavity, subcylindrical to ampulliform, straight to geniculate-sinuous; proliferating several times percurrently near apex, rarely sympodially. Conidia scolecosporous, hyaline, smooth, flexuous, rarely straight, granular, thin-walled, narrowly obclavate, apex subobtuse, base long obconically truncate, tapering to a truncate hilum, 3–multiseptate (Adapted from Quaedvlieg et al. 2013).
Type species: Neoseptoria caricis Quaedvl., Verkley & Crous
Notes: Neoseptoria was introduced by Quaedvlieg et al. (2013) with N. caricis as type species. Neoseptoria morphologically resembles Septoria but differs in having mono- to polyphialidic conidiogenous cells that proliferate per currently at the apex. Phylogenetically, Neoseptoria is a distinct genus in Mycosphaerellaceae.
