Description: Thallus crustose, usually episubstratic, ecorticate, granular-verrucose, sometimes patchily sorediate, pale whitish grey to pale green, often with yellow-orange to rusty red patches which may extend over most of the thallus, rarely immersed and inconspicuous. Apothecia rather frequent, on long stalks, pin-like, (0.4-)1-2 mm tall, 5-15 times as long as width of stalk; stalk 70-150 µm thick, shiny black, epruinose; capitulum broadly to narrowly obconical, 0.2-0.5 mm across, the mazaedium pale to dark brown, often with a yellow tinge. Exciple well-developed, epruinose consisting of numerous layers of interwoven but largely periclinally arranged hyphae; hypothecium obconical, medium brown, with a convex upper surface. Asci cylindrical to narrowly clavate, distinctly stalked, formed singly or in short chains, disintegrating early, with uni- to biseriately arranged spores. Ascospores 1-celled, dark brown, globose, 5.5-8 μm wide, thick-walled, coarsely and irregularly fissured at maturity. Photobiont chlorococcoid (Trebouxia). Spot tests: thallus K-, C-, KC, P-, except the pigmented parts, which react K+ deep red; ascospore mass with a yellowish, K+ red pigment. Chemistry: a quinoid pigment. Note: a cool-temperate to boreal-montane, circumboreal species found on acid bark, especially of very old oaks, Castanea and conifers, on faces protected from rain, sometimes on decorticated stumps and even charred wood, reported as tolerant of air pollution and expanding in northern Europe, but rare and bound to natural habitats throughout Italy.
