Saprobic on stems and twigs of herbaceous and woody plants in terrestrial or aquatic habitats. Sexual state: Ascomata scattered to gregarious, immersed to superficial, globose to lenticular, dark brown to black, glabrous or with brown hyphae. Ascomatal opening short-papillate or undeveloped, central with or without brown short setae. Peridium composed of hyaline to brown, polygonal to angular, thin-walled cells. Hamathecium of cellular, septate and branched pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical to broadly clavate, with a short pedicel, and a shallow ocular chamber at rounded apex, basal to somewhat lateral. Ascospores bi-seriate to tri-seriate, sometimes fasciculate, narrowly fusiform to broadly cylindrical, filiform in some species, straight or slightly curved, mostly 1–3-septate (28–36-septate in some species), hyaline, smooth, surrounded by an entire mucilaginous sheath or elongated appendage-like sheath. Asexual morphs “Stagonospora”-like or “Dendrophoma”-like. Conidiomata pycnidial, globose, ostiolate. Conidiogenous cells enteroblastic. Conidia cylindrical, hyaline, smooth, 2-3-septate or one-celled.
