Description: Thallus crustose, episubstratic, granular to minutely squamulose, greenish grey to brownish green, very rarely completely endosubstratic. Apothecia long-stalked, pin-like, 1-2 mm high, the stalk slender, 0.05-0.1 mm thick, shining black, epruinose or with a faint white pruina in upper part, consisting of periclinally arranged, brown hyphae. Capitulum obconical to lenticular, 0.2-0.3 mm across, usually faintly white-pruinose on the lower side, with a well-developed, brown mazaedium. Exciple well-developed, of periclinally arranged hyphae, continuous with the stalk tissue; hypothecium pale brown, obconical, with a convex upper surface. Asci short-cylindrical or irregular, formed in chains, dissolving early, with 1-seriate to irregularly arranged ascospores. Ascospores 1-celled, brown, globose, 3-4 µm wide, with a smooth to irregularly cracked wall. Photobiont chlorococcoid, with rectangular cells (Stichococcus). Spot tests: thallus K-, C-, KC-, P-. Chemistry: thallus with two unidentified substances.
Note: a widespread holarctic species found on acid-barked deciduous trees, conifers and lignum, sometimes even on Quercus ilex, in forests and woodlands; widespread in upland areas throughout the country, but most common in the Alps.
