Distribution: N - TAA (Nascimbene & al. 2014, Nascimbene 2014).

Description: Thallus crustose, poorly evident, endosubstratic or thinly episubstratic, greenish grey. Apothecia short-stalked, pin-like, epruinose. Stalk shining black, 0.3-0.4 mm high, of sclerotized, dark, anticlinally arranged, irregularly interwoven hyphae. Capitulum obconical to lenticular, with a well-developed, cup-shaped exciple of anticlinally (in outer part) or periclinally (in inner part) arranged hyphae; mazaedium well developed, black; hypothecium dark brown, with a flat to slightly convex upper surface. Asci cylindrical, formed singly, dissolving early, with uniseriately arranged ascospores. Ascospores 1-septate, dark brown, broadly ellipsoid, 9.5-13.5 x 5-6.5 µm, with a thick, first smooth, then irregularly cracked wall. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; ascomata I- in all parts. Chemistry: thallus with low amounts of several unidentified compounds.

Note: a species found on the bark of conifers (most often Pinus sylvestris); recently-described and still with a few records in the Alps, but probably more widespread.
