Distribution: N - Frl, Ven (Lazzarin 2000b, Nascimbene 2002, 2008, Nascimbene & Caniglia 2003c), TAA (Nascimbene & al. 2006, 2007b, Bilovitz & al. 2014b), Lomb, Piem (Isocrono & al. 2004).

Description: Thallus crustose, tartareous white, thick, obscuring the form of the underlying plant remains, of contiguous, granular, 0.1-0.3(-0.5) mm wide warts. Cortex poorly developed, hyaline, 5-10 µm thick, medulla mostly lacking; algal layer: 70-100 µm thick. Apothecia lecideine, sessile, 0.5-1(-1.5) mm across, dark brown to black, rounded to somewhat deformed, with an initially concave to flat, then convex disc, and a thin, smooth, finally excluded proper margin. Proper exciple thin, dark reddish brown within, colourless in outer part, laterally 50-80 µm, basally 95-250 µm wide, composed of radiating hyphae with 1-4.5 µm to apically 2-6.5 µm wide lumina; epithecium pale brown to reddish brown, often poorly delimited towards the hymenium, 5-15 µm high, K-, N-; hymenium colourless, sometimes with pale brown stripes, more rarely with blackish-blue granules of "hypnorum-blue", 55-75 µm high; paraphyses coherent, mostly simple, 1.5-2(-2.5) µm thick at mid-level, the apical cells distinctly capitate, up to 4(-6.5) µm wide, with brown-pigmented walls; hypothecium dark reddish brown, usually without green granules. Asci clavate, with an I+ blue tholus and an internal, darker I+ tubular structure, the external gel I+ faintly blue, Porpidia-type. Ascospores 1-celled, hyaline, ellipsoid, (9-)11-16(-19) x 4-5(-6) µm, often with a rough, c. 0.5 µm thick perispore. Conidia ellipsoid. Photobiont chlorococcoid, the cells 6-12 µm in diam. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a circumpolar, arctic-alpine to boreal-montane lichen found on mosses and plant debris over calcareous substrata; most common in the Alps, but probably occurring throughout the Apennines. The species does not belong to Lecidea nor to Mycobilimbia and is closely related to Romjularia (Fryday & al. 2014).
