Epiphytic on branches, twigs or leaves appearing as blackened areas. Superficial mycelium superficial, dark, forming a flattened mat, but frequently with erect branches. Hyphae straight to irregularly curved, occasionally anastomosing, septate, finely or coarsely roughened, pale brown to brown, or hyphae of some species formed on one cell-thick plate. Sexual morph: Ascomata unilocular superficial, partially immersed in hyphae, scattered to gregarious, globose to subglobose, dark brown to brown, membranous, ostiolate or without ostiole, surrounded by numerous, barrel-shaped, brown, obtuse, sometimes septate, verrucose hyphal append- ages. Peridium comprising of dark, brown cells of textura angularis, thick-walled. Hamathecium lacking pseudoparaphyses. Asci 2–8-spored, fasciculate, bitunicate, ellipsoidal to broadly ellipsoidal, apedicellate, thin-walled, ocular chamber present. Ascospores 2–3-seriate to overlapping, ellipsoidal to fusiform, pale brown to dark brown, middle cell larger than other cells, 3–7-multi-septate, or dictyoseptate, smooth or thick-walled, constricted at the septa (Hyde et al. 2013; Hongsanan et al. 2020b). Asexual morph: Antennatula with Hormisciomyces, or Trichothallus with Plokamidomyces (Hughes 1974).
Notes: Euantennariaceae was introduced by Hughes (1972). Taxa of this family are characterized by superficial, brown to dark brown, cylindrical mycelium, consisting of septate hyphae with smooth to coarsely roughened walls, slightly constricted at the septum (Hughes 1972). Species in this family are similar to Metacapnodiaceae in having ellipsoidal asci and ellipsoidal ascospores and differ from Metacapnodiaceae in lacking periphysoids (Eriksson 1981). However, Metacapnodium has been accepted as a genus in Eurotiomycetes based on its phylogeny. Kirk et al. (2008) included nine genera and 28 species while ten genera were accepted by Hyde et al. (2013). Hongsanan et al. (2020b) and Wijayawardene et al. (2022) accepted seven genera in Euantennariaceae.
Type genus: Euantennaria Speg., Physis, B. Aires 4: 284 (1918).
