Saprobic on or between hairy leaves or leaf lamellae of hosts. Sexual morph: Ascomata perithecioid, superficial, solitary, subglobose to globose, ovoid or pyriform, light to dark brown to black, ostioles without periphyses, apapillate, setose. Setae simple, arising at the upper part, usually, apex rounded, occasionally tapering towards the apex, dark brown, straight or curved, septate, slightly constricted at the septa. Wall of ascoma multi-layered, comprising brown to dark brown cells of textura angularis, apex cells darker and thicker walls, lacking interascal tissue cells. Hamathecium lacking paraphyses. Asci 8-spored, bitunicate, oblong to ovoid, ellipsoid, to nearly subcylindrical, without a pedicel, apex rounded, with or without apical structures, sometimes hymenial jelly reddish in Lugol’s solution, embedded in a gelatinous matrix. Ascospores overlapping 2–3-seriate, ellipsoid to fusiform, sub-clavate, tapering towards both ends, hyaline or pale grey to lightly brown, 0 to trans-septate, not constricted or slightly constricted at the septa, thin-walled, with or without gelatinous sheath, guttulate. Asexual morph: Undetermined.
Notes – Gueidan et al. (2014) established Epibryaceae to accommodate most Epibryon species, including the type species E. plagiochilae, and Leptomeliola ptilidii, Cladophialophora minutissima and some rock-inhabiting taxa. The key characters of Epibryaceae are globose to subglobose, setose ascomata and oblong to fusiform to sub-clavate ascospores. The family contains a single genus Epibryon with sexual morphs and asexual collections are from rocks and vascular plants (Gueidan et al. 2014).
