Saprobic or parasitic on wood, leaves or isolated from soil, sometimes fungicolous and lichenicolous. Sexual morph: Ascomata perithecial or cleistothecial, solitary or gregarious, semi-immersed to superficial, sometimes sitting on a subiculum, cupuliform, globose to subglobose, yellow, orange, brown or black, membranaceous, tuberculate or smooth, glabrous or with setae or irregular appendages, collapsing or collapsing laterally or not collapsing, with or lacking ostioles. Peridium composed of membranaceous, yellow or brown or olivaceous brown or reddish brown to hyaline cells of textura angularis to textura epidermoidea to textura prismatica. Paraphyses absent or filiform or cylindrical, septate, branched or unbranched. Asci 8-spored, unitunicate, cylindrical to clavate, pedicellate, apex rounded or blunt, apical ring indistinct or absent, evanescent. Ascospores uni- or bi-seriate or overlapping, hyaline to brown, ellipsoidal to fusiform, straight or curved, 0–1-septate, verrucose or smooth-walled, sometimes faintly striate, mostly with guttules. Asexual morph: Hyphomycetous. Mycelium hyaline to light brown, superficial, effused. Conidiophores mononematous, macronematous, hyaline, unbranched, aseptate. Conidia oval to ellipsoidal, usually aseptate, hyaline, smooth-walled, guttulate. Coelomycetous. Conidiomata globose to subglobose, dark brown to black. Peridium composed of brown cells of textura angularis, becoming hyaline towards the inner conidiogenous region. Conidiophores hyaline, cylindrical to subcylindrical, septate. Conidia oval to ellipsoidal, 0–2-septate, hyaline, smooth-walled, guttulate (adapted from Samuels & Barr 1997, Hyde et al. 2020e).
Notes – The family Niessliaceae was established by Kirschstein (1939) to currently accommodate 21 genera (Hyde et al. 2020e, Wijayawardene et al. 2020). They usually have perithecial ascomata, unitunicate asci with inamyloid apical ring and hyaline, ellipsoidal to fusiform ascospores (Samuels & Barr 1997, Hyde et al. 2020e). Eight genera have molecular data, Eucasphaeria, Myrtacremonium, Neoeucasphaeria, Niesslia, Pseudohyaloseta, Rosasphaeria, Trichosphaerella, Valetoniellopsis, and they are aggregated in Niessliaceae (Hyde et al. 2020e, this study, 83%ML/1.00BY).
Type genus – Niesslia Auersw., in Gonnermann & Rabenhorst, Myc. Europ., Abbild. Sämmtl. Pilze Eur. 5-6: 30 (1869).
