Neoascochyta Qian Chen & L. Cai, Stud. Mycol. 82: 198 (2015)
Index Fungorum number: IF 814064; Facesoffungi number: FoF 07462, 13 morphological species (Species Fungorum 2021), 13 species with molecular data.
Saprobic on leaf. Sexual morph: Ascomata pseudothecial immersed or erumpent, solitary or confluent, globose to subglobose, ostiolate. Asci cylindrical to subclavate, slightly curved, short pedicellate or sessile, 8-spored, bitunicate. Ascospores cylindrical to ovoid, ellipsoidal, hyaline, 1- septate, symmetrical or asymmetrical, constricted at the septum, biseriate or irregular uniseriate. Asexual morph: Conidiomata pycnidial, globose to sub globose, or irregularly shaped, superficial on or immersed into the agar, solitary or confluent, ostiolate, sometimes with a short neck. Pycnidial wall pseudoparenchymatous, 2–7-layered, outer wall pigmented, thick. Conidiogenous cells phialidic, hyaline, smooth, globose to flask-shaped, short obpyriform, or ampulliform to doliiform. Conidia variable in shape, hyaline, smooth- and thin-walled, i.e. fusoid to cylindrical, obclavate-ovoid to ellipsoidal, incidentally slight curved, uniseptate or aseptate, eguttulate or guttulate (Adapted from Chen et al. 2015).
Type species: Neoascochyta exitialis (Morini) Q. Chen & L. Cai
Notes: Neoascochyta was introduced by Chen and Cai (2015) with N. exitialis as type species. Neoascochyta is characterized by pseudothecial ascomata, cylindrical to subclavate asci, cylindrical to ovoid, hyaline 1- septate ascospores. The asexual morph is coelomycetous and is characterized by pycnidial conidiomata, pseudoparenchymatous wall, obpyriform, or ampulliform to doliiform conidiogeneous cells and hyaline fusoid to cylindrical, obclavate-ovoid to ellipsoidal conidia. Neoascochyta morphologically resembles the genus Ascochyta, but is phylogenetically distinct.
