Taxa are saprobic on dead plant material. Ascomata are apothecial and rarely perithecial. Apothecia are cupulate to discoid and sessile or stipitate. The margins are covered by hairs and hairs are smooth or granulate, cylindrical, tapered to the apex, septate and straight to flexuous or hooked. The ectal excipulum is composed of cells of textura angularis, prismatica or oblita and medullary excipulum is composed gelatinous loosely arranged hyphae. Paraphyses are filiform, cylindrical or lanceolate, septate or aseptate and simple or branched. Asci are 4–8-spored, amyloid or non-amyloid and sometimes arising from croziers. Ascospores are globose, ellipsoid or fusoid, aseptate or 1–3-septate and guttulate (Jaklitsch et al. 2016, Baral et al. 2009, Han et al. 2011, Quijada et al. 2017). Asexual morphs are hyphomycetous. Conidiogenesis is phialidic or sporodochial. Conidia are aseptate, hyaline or brown, branched and muriform or in chains (Jaklitsch et al. 2016).
