Apothecia common, 2–8 mm wide, commonly with urceolate base when young, shortly to markedly pedicellate; pedicel hollow, to 5 mm long; disc concave becoming ±flat, dull brown; thalline exciple entire, often involute becoming crenate. Ascospores 7.5–8.5 × 4–6 µm. Pycnidia abundant to sparse, numerous at apices of broader lobes. CHEMISTRY: cortex K+ yellow; medulla KC+ red, P-.
