Coniochaeta (Sacc.) CookeNotes.The genus Coniochaeta was introduced based on C. ligniaria (Grev.) Massee as the type species (García et al. 2006; Silva et al. 2023). The sexual morph of Coniochaeta is characterized by superficial or semi-immersed ascomata, cylindrical, clavate, subglobose, or globose asci, and narrowly ellipsoid to fusoid, broadly ellipsoidal to globose ascospores (García et al. 2006; Silva et al. 2023). The asexual morph of Coniochaeta is characterized by phialides with very short lateral necks, periclinal wall thickening, and flaring collarettes (Gams 2000; Weber 2002; Silva et al. 2023). Meanwhile, the genus Coniochaeta has various shapes of conidia, such as ellipsoidal to cylindrical, ellipsoid, ellipsoidal, cylindrical or curved, and bacilliform to allantoid (Arnold et al. 2021; Kabtani et al. 2022; Silva et al. 2023; Crous et al. 2025). Presently, 134 species of Coniochaeta are recorded in Index Fungorum (2025) (published on the Internet at http://www.indexfungorum.org, The Royal Botanic Gardens, Kew. [Retrieved 16 March 2026]).
