Description: Thallus crustose, endosubstratic or thinly episubstratic, more or less glossy, pale grey to pale yellowish brown, sometimes with an olivaceous tinge, not mealy. Apothecia lirelliform, immersed in the thallus, simple or often lobate or dendritically branched, 1-3(-5) x 0.1-0.3(-1) mm, with an expanded, grey-black disc, and a proper margin without evident excipular lips; a thin, entire, inconspicuous thalline margin is rarely present in young ascocarps. Proper exciple pale to dark brown, 12-15 µm thick laterally, widening to 25 µm in upper part usually extending below the hymenium; epithecium brown, 5-15 µm high; hymenium colourless, inspersed with oil droplets, (45-)55-85(-120) µm high, I-; paraphyses coherent, c. 1.5 µm thick, sparsely branched in upper part, with brownish, slightly expanded, to 2 µm wide apical cells; subhymenium hyaline; hypothecium dark brown, 12-40 µm high. Asci 8-spored, clavate, to cylindrical-clavate, non fissitunicate, dehiscent by an apical split, K/I-, Graphis-type. Ascospores 3(-5)-septate, with lens-shaped cells, at first hyaline but soon turning brown, (12-)13-25(-30) x (4-)6-8(-9) µm, I+ red or reddish brown. Photobiont trentepohlioid. Spot tests: cortex K- or K+ dirty yellow to orange brown, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.

Note: a mild-temperate to humid subtropical, mainly Atlantic species in Europe, known from a single hyperhumid station in Italy. It is included in the Italian red list of epiphytic lichens as “Data Deficient” (Nascimbene & al. 2013c).
