Description: Thallus crustose, endosubstratic and poorly visible. Apothecia stalked, pin-like, the stalk slender, 0.4-1.4 mm high, 0.04-0.08 mm thick, densely yellowish green-pruinose except sometimes in the black lowermost part, the inner part of periclinally arranged, medium brown hyphae, the outer part of dark brown, sclerotized hyphae. Capitulum spherical, 0.1-0.2 mm across, yellowish-green-pruinose, with a poorly developed excipulum of periclinally arranged hyphae, continuous with the stalk tissue and often reduced to a small basal collar. Mazaedium well-developed, dark to medium brown, but usually greenish-pruinose at least in young stages; hypothecium dark brown, with a convex upper surface. Asci cylindrical or irregular, formed in chains, dissolving early. Ascospores 1-celled, medium brown, globose to cuboid, 3-4.5 µm wide, the wall with a very minute ornamentation of tiny ridges and conspicuous, larger irregular cracks. Photobiont chlorococcoid, with rectangular cells (Stichococcus). Spot tests: thallus K-, C-, KC-, P-. Chemistry: thallus and pruina of the apothecia with pulvinic and vulpinic acids.

Note: on decorticated stumps of deciduous and coniferous trees, more rarely on bark and siliceous rocks in old humid forests, on faces slightly protected from rain. Reported from both the Alps and the Apennines, but rare. It is included in the Italian red list of epiphytic lichens as “Endangered” (Nascimbene & al. 2013c).
