Thallus epiphloeodal, pale yellowish green, grey-green or pale grey-brown, 40–150 µm thick, continuous to rimose, smooth, minutely rugulose, verruculose or coarsely verrucose, corticate; prothallus pale grey, dark grey-brown or not apparent. Algae Trentepohlia; cells 5–12 × 5–9 µm. Perithecial verrucae convex, hemispherical or subglobose, 0.5–1 mm diam.; wall containing a layer of colourless crystals; apex slightly concave, plane or rounded; ostiole inconspicuous; periostiolar area concolorous with the thallus or pinkish brown. Involucrellum pale yellowish brown to orange-brown, forming a ±globose shell that often encloses the exciple. Exciple 20–30 µm thick, hyaline to pale brown. Centrum 0.35–0.67 mm wide. Periphyses 20–40 µm long. Asci broadly fusiform to oblong, 210–410 × 35–65 µm. Ascospores narrowly to broadly ellipsoidal or fusiform, muriform, with 17–30 transverse septa, each loculus with (1–) 2–4 (–6) longitudinal or diagonal septa, 58–148 × 18–41 µm; perispore 1–4 (–5) µm thick. Pycnidia immersed in 0.1–0.2 mm diam. verrucae. Conidia fusiform, 2–4 × c. 1 µm. | ||
