Description: Thallus crustose, usually verrucose, rarely almost endosubstratic, intensely yellowish green (but grey forms without rhizocarpic acid are known from the Alps). Cortex 14-25 µm thick, with numerous small yellowish green crystals in lower part. Apothecia black, epruinose, immersed in thalline warts, (0.2-)0.4-1 mm across, with a black mazaedium. Exciple uniformly thin throughout, 14-28 µm wide, blackish brown, of sclerotized, strongly intertwined hyphae with thickened walls; hypothecium very thin, pale to medium brown. Asci pyriform, dissolving early, with 2-3-seriately arranged spores. Ascospores 1-septate and constricted at septum, brown, broadly ellipsoid, 17-22 x (6-)7-10(-11) µm, with a smooth wall. Pycnidia rather rare, at first globose to ellipsoid, later confluent and forming irregular, up to 0.4 mm wide aggregates. Conidia simple, hyaline, ellipsoid, 3-4 x c. 1.5 µm. Spot tests: thallus K-, C-, KC-, P-. Chemistry: thallus with rhizocarpic acid (rarely lacking in some forms), epanorin and two unidentified substances.

Note: a mainly boreal-montane, circumpolar lichen found in upland areas on hard, dry wood, especially of conifers, on wooden fences and fence-posts, often together with Ramboldia elabens. Widespread throughout the Alps, reaching South up to the mountains of Calabria.
