Photobiont trebouxioid, cells 5–8 µm diam. Apothecia applanate to broadly sessile, 0.25–0.5 mm diam. and 80–100 µm high; disc plane, dark brown, non-pruinose; proper margin distinct, dark brown, non-pruinose. Excipulum composed of radiating and anastomosing hyphae embedded in a gelatinous matrix, 30–50 µm broad, colourless but externally covered by a dark brown, granular layer. Hypothecium 5–10 µm high, colourless; epithecium 5–10 µm high, dark brown granulose. Hymenium 70–90 µm high, colourless. Asci clavate, 60–80 x 12–15 µm. Ascospores 4–8/ascus, ellipsoid, submuriform with 3–5 transverse septa and 0–1 longitudinal septa per segment, with slight constrictions at the septa, 12–16 x 6–8 µm, 1.8–2.2 times as long as broad, colourless.
