Coniochaeta, typified by Coniochaeta ligniaria, is characterized by dark brown to black, solitary or aggregated, typically setose, pyriform to globose ascomata, with or without ostioles. The peridium is membranaceous to pseudoparenchymatous, or rarely coriaceous (Damm et al. 2010, Samarakoon et al. 2018, Jones et al. 2019). A paraphysate hamathecium is present or absent. Asci are unitunicate and thin-walled, with a small non-amyloid, apical ring and ascospores are one-celled, usually dark brown and often laterally compressed, with a germ slit (Weber 2002, Asgari et al. 2007). In this study, we introduce Coniochaeta velutina from host, Phyllostachys viridis to this genus.
