Description: Thallus crustose, endosubstratic and poorly evident or more often episubstratic and granular-verrucose, greenish to yellowish grey with a bluish tinge. Apothecia long-stalked, pin-like, epruinose or with a whitish pruina on the lower side of capitulum. Stalk black to dark reddish brown, 0.5-1.3 mm high, of sclerotized, dark, irregularly interwoven hyphae, in section distinctly reddish brown, sometimes with strands of granular crystals, the outer layer covered with a very thin, transparent, non-amyloid gelatinous sheath. Capitulum narrowly obconical to lenticular, with a well-developed, cup-shaped exciple of intertwined, sclerotized hyphae; mazaedium well developed, black; hypothecium blackish brown, with a convex upper surface. Asci narrowly clavate to cylindrical, formed singly, dissolving early, with partly 2-seriate ascospores. Ascospores first simple, then (when released from asci) 1-septate, dark brown, broadly ellipsoid to ellipsoid, (9-)11-12 x (4-)6-7 µm, with a thick, minutely verrucose to areolate wall. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; ascomata I+ deep blue to black in all parts. Chemistry: thallus with no lichen substances or with placodiolic and sometimes 4-O-methyhypoprotocetraric acids.
Note: a mainly cool-temperate to boreal-montane, circumpolar species found on lignum of decorticated stumps and trunks of conifers in upland areas. It is included in the Italian red list of epiphytic lichens as “Critically Endangered” (Nascimbene & al. 2013c).
