Colonies hypophyllous, thin to subdense, subvelvety, spreading, up to 5 mm in diameter, confluent. Hyphae substraight to crooked, branching opposite at acute to wide angles, loosely to closely reticulate to form a mycelial mat, cells 18–28 × 6–8 µm (x̅ = 24.25 × 7.42 µm, n = 10). Appressoria absent. Haustoria forming at the tips of lateral hyphal branchlets, enlarged, ovate to globose, slightly divided like a slit at the centre, 10–13 × 7–12 µm (x̅ = 11.5 × 9.5 µm, n = 10), stalk cells one to three in number, cylindrical, 9–30 × 5–7 µm (x̅ = 20.25 × 6 µm, n = 10). Sexual morph: Thyriothecia orbicular, oval, ellipsoidal to elongated, dehisce longitudinally at the centre, 350–800 × 300–450µm (x̅ = 575 × 375 µm, n = 10), margin fimbriate, fringed hyphae run parallel, compact. Asci oval to globose, octosporous, bitunicate, 60–85 µm (x̅ = 72.5 µm, n = 10) in diameter. Ascospores conglobate, brown, uniseptate, strictly constricted at the septum, 32–44 × 18–26 µm (x̅ = 38 × 22 µm, n = 10), wall punctate to echinulate. Asexual morph: Pycnothyria many, similar and smaller than thyriothecia. Pycnothyriospores deep brown, globose to pyriform, slightly papillate, 9–12 × 8–11 µm (x̅ = 10.5 × 9.5 µm, n = 10).
