Synonyms: Biatora cupreiformis (Nyl.) Arnold; Biatora poetschiana Körb.; Lecidea miscella Sommerf. non Ach.; Lecidea strasseri Zahlbr.; Mycobilimbia berengeriana (A. Massal.) Hafellner & V. Wirth
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). C - Tosc, Umb (Ravera 2000, Ravera & al. 2006), Abr (Nimis & Tretiach 1999). S - Cal (Puntillo 1996).
Description: Thallus crustose, tartareous white, c. 0.2 mm thick, obscuring the form of the underlying plant remains, of contiguous, granular, 0.1-0.3(-0.5) mm wide warts. Medulla white, I-. Apothecia lecideine, sessile, 0.5-1(-1.5) mm across, dark brown to black, with an initially flat, then convex disc, and a thin, smooth, finally excluded proper margin. Proper exciple thin, dark reddish brown within, colourless in outer part; epithecium pale brown, K-, N-; hymenium colourless, 60-65 µm high, I+ blue, rarely with scattered blue-violet granules reacting K+ green; paraphyses conglutinate, mostly simple, 1.5-2(-2.5) µm wide at mid-level, the apical cells capitate and up to 4(-6) µm wide, with brown-pigmented walls; hypothecium dark reddish brown, usually without granules. Asci clavate, with a 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, without an epispore. 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).
