Descriptions
Thallus squamulose ± closely attached, 4-8(-10) cm diam., on a fine, black prothallus, projecting to 5 mm beyond squamules, distinctly coarsely fibrous at margins. Squamules discrete, scattered, rounded at margins, becoming irregularly lobate-incised and often slightly laciniate-elongate (1 × 3 mm), at length confluent in a closely attached ± imbricate mosaic at centre, ± distinctly convex and minutely lobulate at margins which are also minutely white- pubescent or "frosted", bright lettuce-green when wet, pale greenish-grey when dry, becoming yellow-brown to dark red-brown on storage. Cephalodia larger than squamules, lobate-crenate to placodioid, between squamules, 0.5-2.0 mm diam., pale grey-blue, concolorous with thallus on storage, occasionally overgrowing squamules, sometimes striate-cracked, wrinkled-plicate, not flattened. Apothecia forming conglomerate groups with disc, obscured by placodioid or ± convolute, thalline lobules and ridges, disc pale to dark red-brown, concentrically striate beneath thalline tissue, 2-6(-10) mm diam., margins thick, inrolled, crenulate-striate, rather waxy, thalline exciple smooth. Ascospores oval-ellipsoid, apices rounded or pointed 13-17 × 8.3-10.2 µm, wall 1.7-3.0 µm thick.
