Classification: Incertae sedis, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Parasitic on leaves and leaf litters. Sexual morph: Ascomata perithecial, solitary or scattered, semi-immersed to superficial, globose to subglobose, black, membranaceous, surrounded by hyaline hyphae, ostiolate, periphysate. Peridium composed of membranaceous, brown cells of textura angularis. Paraphyses absent. Asci 8-spored, unitunicate, cylindrical, pedicellate, apex rounded or blunt, apical ring distinct. Ascospores bi-seriate, hyaline, ellipsoidal to fusiform, straight or curved, 1-septate, verrucose or smooth-walled, sometimes faintly striate, mostly with guttules. Asexual morph: Coelomycetous. Conidiomata semi-immersed, globose to subglobose, acervuloid, dark brown to black. Peridium composed of brown cells of textura angularis, becoming hyaline towards inner conidiogenous region. Conidiophores hyaline, cylindrical to subcylindrical, septate, branched, giving rise to 1–2 conidiogenous cells. Conidiogenous cells fusiform to ellipsoidal, hyaline, phialidic, straight to slightly curved. Conidia in natural environment, cylindrical to oblong, slightly curved, 0–1-septate, hyaline, smooth-walled, guttulate; in culture sporulating, falcate, 0–2-septate, hyaline, smooth-walled, guttulate (adapted from Crous et al. 2007, 2016).

Notes – Eucasphaeria was established by Crous et al. (2007), and the type E. capensis was sequenced by Vu et al. (2019). Subsequently, Eucasphaeria rustici and E. proteae were introduced based on morphology and phylogenetic results (Crous et al. 2016, 2020a). In this study, Eucasphaeria is sister to Neocucasphaeria and Rosasphaeria (99%ML/1.00BY).

Type species: Eucasphaeria capensis Crous, in Crous, Mohammed, Glen, Verkley & Groenewald, Fungal Diversity 25: 21 (2007).

Other accepted species: Species Fungorum – search Eucasphaeria.
