Saprobic on leaves of unidentified host. Sexual morph: Undetermined. Asexual morph: Conidiomata 194–259 μm diam., 187–206 μm high, pycnidial, small, very dense or compact, rounded circular or irregular, black, verrucose, growing from a subcuticular hypostroma, forming a thin celled layer, pseudoparenchymatous, translucent olive-brown crust, depressed in the dried state, papillate. Conidiomatal wall outer layer thick, 7–8 layered, composed of thick-walled dark brown to black cells of textura globulosa, innermost wall thin, 2–3 layered of textura angularis, becoming hyaline.

Conidiogenous cells 3.5–5.9 μm × 2.3–3.5 μm, holoblastic, cylindrical or slightly irregular, short, sparsely branched, mostly at the base, hyaline or very pale brown, septate, smooth. Conidia 20–26 μm × 3.0–4.3 μm (x̅ = 21.8 × 3.4 μm, n = 20), straight, curved or irregular, truncate at the base, obtuse at the apex hyaline or pale brown, 3-transversely septate, usually thin and smooth-walled or verruculose.
