MycoBank number: MB 80650; Index Fungorum number: IF 80650; Facesoffungi number: FoF 06868; 79 species.
Saprobic on dead wood or pathogenic on plants. Sexual morph: Stromata solitary, erumpent, comprising pseudoparenchymatous cells. Ectostromatic disc well or poorly developed, brown to black, comprising small cells of textura prismatica. Ascomata perithecial, arranged in valsoid configuration, immersed, aggregated, globose to subglobose, coriaceous, brown to black, papillate, ostiolate. Papilla upright, central, broad, sometimes converging, comprising brown cells of textura porrecta. Peridium comprising outer, thick-walled, brown cells of textura angularis and inner, thick-walled, hyaline, compressed cells of textura angularis. Paraphyses broad, cellular, septate, attached to base, longer than asci. Asci 8-spored, unitunicate, ellipsoid to cylindrical, pedicellate, rounded at apex with a J-, apical ring. Ascospores overlapping uni- to biseriate, hyaline or initially hyaline, brown at maturity, irregularly fasciculate, ellipsoid, fusoid or elongate, 1–3-septate, often distoseptate, with end-cells pale brown or hyaline, sometimes end-cells pointed, straight or curved not constricted at the septa, guttulate, smooth-walled. Asexual morph: Coelomycetous. Conidiomata acervular, solitary, erumpent through outer periderm layers of host or immersed, scattered, surface tissues above somewhat dome-shaped. Conidiomatal wall composed of thin- walled, vertically arranged dark brown cells of textura angularis. Conidiophores branched at the base or not, cylindrical to globose, septate or aseptate, hyaline or hyaline at the apex, pale brown at the base. Conidiogenous cells terminal, hyaline, annellidic, cylindrical, sometimes with setulose apical appendages. Conidia hyaline to dark brown, curved, broadly fusiform to cylindrical or clavate, smooth-walled, 4–6-distoseptate, sometimes the apical and basal cell darker than other cells with hyaline tip in apical cell.
Type genus – Coryneum Nees
Notes – Coryneaceae was introduced by Corda (1839a) to accommodate Coryneum which was typified by C. umbonatum and comprises only one genus.
