Index Fungorum number: IF 514648; Facesoffungi number: FoF 00249, 20 morphological species (Species Fungorum, 2022), 20 species with molecular data.
Saprobic or pathogenic on host. Asexual morph: Pycnidia solitary to confluent, on upper surface of agar, globose to irregular, with mycelial outgrowths, with papillate ostioles, sometimes developing long necks, honey to olivaceous/olivaceous-black, the wall with pseudoparenchymatal cells. Conidiogenous cells hyaline, phialidic, discrete. Conidia slightly yellowish, aseptate, or septate, ellipsoidal to cylindrical, usually attenuate at one end, often guttulate. Sexual morph: Unknown (Adapted from de Gruyter et al., 2010).
Type species: Neosetophoma samarorum (Desm.) Gruyter, Aveskamp & Verkley
Notes: Neosetophoma was introduced by de Gruyter et al. (2010) with N. samarorum as type species. Neosetophoma is characterized by solitary to confluent pycnidia, hyaline, phialidic, discrete conidiogenous cells and slightly yellowish, aseptate, or septate, ellipsoidal to cylindrical conidia. Several authors added new species to Neosetophoma (De Gruyter et al., 2010; Liu et al., 2015; Karunarathna et al., 2017; Thambugala et al., 2017b; Tibpromma et al., 2017; Hyde et al., 2018, 2019, 2020; Wanasinghe et al., 2018; Marin-Felix et al., 2019; Phookamsak et al., 2019). Neosetophoma is morphologically and phylogenetically a distinct and well-defined genus in Phaeosphaeriaceae. Molecular markers available for Neosetophoma are LSU, SSU, ITS, TEF1, BTUB and RPB2.
