Maculae white or fawn, scattered, effigurate to ±reticulate. Pseudocyphellae occasional, scattered, minute, punctiform, white. Phyllidia occasional, marginal, simple or finger-like to branched-coralloid, flattened, constricted at base, 1–3 mm tall. Medulla white. Photobiont Nostoc. Lower surface whitish or pale fawn at margins to pale or dark red-brown centrally, densely tomentose from margins to centre or with a narrow glabrous marginal zone; tomentum silky, entangled to shaggy, white; pseudocyphellae scattered, conspicuous at margins, conical-verruciform, 0.1–0.5 mm diam. with a white decorticate area.
