Neoconiothyrium Crous, in Crous et al., Persoonia 39: 379 (2017)
Index Fungorum number: IF 823385; Facesoffungi number: FoF 08174, 4 morphological species (Species Fungorum 2021), 4 species with molecular data.
Saprobic on leaves. Sexual morph: Unknown. Asexual morph: Conidiomata superficial, ellipsoid to obpyriform, solitary, with 1–2 papillate ostioles; conidiomata hyaline on agar, becoming pigmented during sporulation. Conidiomatal wall comprises 3–6 layers of thick-walled cells; surface with or without setae. Conidiophores reduced to conidiogenous cells lining the inner cavity, hyaline, smooth, doliiform to ampulliform, phialidic, with periclinal thickening or percurrent proliferation. Conidia solitary, hyaline to medium brown, smooth to finely verruculose, ellipsoid to subclavate or subcylindrical, 0–1-septate (Adapted from Crous et al. 2017).
Type species: Neoconiothyrium persooniae Crous
Notes: Neoconiothyrium was introduced by Crous et al. (2017) with N. persooniae as type species. Neoconiothyrium is characterized by superficial conidiomata, doliiform to ampulliform conidiogeneous cells and hyaline to medium brown conidia. Neoconiothyrium differs from Coniothyrium in that, in Coniothyrium, conidiomata are covered in setae and conidia are globose to broadly ellipsoid and aseptate while in Neoconiothyrium, setae are absent and conidia are initially ellipsoid and aseptate, becoming cylindrical and 1-septate.
