Upper surface markedly uneven, but often shining, glaucous-olivaceous when wet, with suffused red-brown margins. Lower surface white at margins, brownish centrally, with densely clustered bundles of silky white to blue-black rhizohyphae, normally projecting beyond lobe margins. Apothecia rare, 0.1–1.5 mm wide; disc concave becoming flat, matt, epruinose, pale to dark red-brown with persistent paler, entire to shallowly sinuous proper exciple, slightly raised above disc; hymenium I+ persistent blue. Ascospores 12–20 × 6–10 µm.
