Epiphytic on branches, twigs or leaves appearing as blackened areas. Superficial mycelium comprising of cylindrical, straight to irregularly curved, septate, pale brown to brown, occasionally anastomosing, finely or coarsely roughened hyphae. Sexual morph: Ascomata superficial, scattered to gregarious, globose to subglobose, brown to dark brown, membranous, ostiolate or without ostiole, surrounded by cylindrical hypha appendages. Peridium composed of thick, dark brown cells of textura angularis, thick-walled. Hamathecium lacking pseudoparaphyses. Asci 2–8-spored, bitunicate, ellipsoidal or fusoid to cylindrical, sometimes obclavate, thin-walled, appedicellate, ocular chamber present. Ascospores irregularly arranged in asci, ellipsoidal, fusoid, pale brown to brown or reddish brown, 2 to 3–7-multi-septate with or without mucronate ends, with or without guttules, rounded at the ends, slightly or not at all constricted at the septa. Asexual morph: Antennatula-like blastic phragmoconidia. Conidiogenous cells, straight, bent, sometimes sigmoid and occasionally apically recurved, some cells enlarged, bluntly mucronate at both ends or truncate at the base. Hormisciomyces-like phialides borne in a whorl at the swollen ends of hyphal branches (phialophores) which arise as upright branches of repent hyphae, more or less cylindrical, phialoconidia minute, hyaline, subglobose, and accumulate in a slimy head (Sugiyama and Hosoya 2020).
Notes: Euantennaria was introduced by Spegazzini (1918) with the type species of Euantennaria tropicicola. Hughes (1974) illustrated four euantennariaceous sooty moulds from New Zealand and asexual morphs of Antennatula and Hormisciomyces. Species of this genus often occur mixed with other sooty mould genera (Metacapnodium with Capnobotrys and Capnophialophora-like synasexual morphs, and Tripospermum) (Sugiyama and Hosoya 2020).
Type species: Euantennaria tropicicola Speg., Boln Acad. nac. Cienc. Córdoba 23(3–4): 549 [no. 448, reprint pages 187] (1919).
