Description: Thallus crustose, corticated, rimose-areolate, greenish grey, grey-yellow to grey-olive, 3-5(-10) mm thick, forming well-delimited, up to 18 cm wide patches, often surrounded by a pale prothallus. Apothecia lecanorine, sessile, round to irregular, 0.5-3 mm across, with a blood-red, flat to slightly convex disc, a slightly paler or concolorous proper margin, and a thalline margin finally often limited to the lower side of the apothecium. Epithecium orange-red, K+ blue turning violet; hymenium colourless to orange in upper part, 50–75 μm high; paraphyses simple, c. 1 μm thick, slightly thickened at tips; hypothecium colourless, up to 400 μm thick. Asci 8-spored, clavate, with a shallow, uniformly K/I + blue apical dome, lacking a distinct ocular chamber or apical cushion, with spirally arranged spores, Ophioparma-type. Ascospores 3-7-septate, hyaline, curved, with one end blunt and the other subulate, 30-60 x 3.5-6 μm. Pycnidia with distinct black ostioles, surrounded by a thalline swelling. Conidia simple, hyaline, bacilliform, 5-10 x c. 1 μm. Photobiont chlorococcoid. Spot tests: cortex K+ pale yellow, C+ pale yellow, P-; medulla K+ yellow-orange, C-, KC+ yellow-orange, P+ yellow-orange, UV+ glaucous white. Chemistry: thallus with usnic and divaricatic acids, plus variable amounts of hypothamnolic and miriquidic acids;, apothecia with haemoventosin and 4-hydroxyhaemoventosin.
Note: an arctic-alpine circumpolar lichen found on steeply inclined surfaces of siliceous rocks in wind-exposed situations, with optimum above treeline; most frequent in the Alps, where it reaches the nival belt, but reaching south to the mountains of Calabria.
