Saprobic on woody substrates in terrestrial habitats. Sexual morph: Ascomata black, perithecial, scattered or gregarious, superficial on host, immersed or sub-immersed in the thick subiculum, globose to subglobose, coriaceous or membranous, turbinate or tuberculate, with or without brown branched setae, collabent or not collapsing. Subiculum brown to dark brown, thick or thin, septate, brittle when dry, branched or unbranched hyphae, with spiny termination. Peridium thick, munk pores present or absent, outer layer composed of black to brown cells of textura angularis, thick-walled; inner layer composed of hyaline cells of textura prismatica, thin-walled. Hamathecium quellkörper present, conical, wide at the base, paraphyses absent. Asci 8-spored, unitunicate, cylindrical to clavate, long or short pedicellate, apex rounded, apical ring indistinct or absent, evanescent. Ascospores 2-seriate to irregularly arranged, hyaline, allantoid, ellipsoid to oval, straight to slightly curved, aseptate, smooth-walled, without appendages, occasionally  with guttules.
