Description: Thallus crustose, episubstratic, continuous to cracked-areolate, pale grey to grey-brown, rarely delimited by a thin dark prothallus. Apothecia frequent, biatorine/zeorine, to 1.5 mm across, scattered to contiguous, with a flat to convex, rust red to brown-red disc and a concolorous or more rarely blackened, slightly raised, often flexuose, at least at the beginning rather glossy proper margin. Proper exciple prosoplectenchymatous, C+ purple in section; epithecium orange, granular, K+ red, C-; hymenium colourless, frequently inspersed with oil droplets; algal layer not present below the hymenium; paraphyses flexuose, 1.5-3 μm thick in lower part, the apical cells only slightly thickened (to 3.5 µm); hypothecium colourless. Asci 8-spored, clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid, 12-16(-17.5) x 6-8 µm, the septum c. 5 µm thick (up to half of spore length). Pycnidia common, immersed, appearing as red dots reacting K+ red. Conidia bacilliform, rarely narrowly ellipsoid, 3-5 x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, N+ violet (in section); apothecia and pycnidia K+ red. Chemistry: non-chlorinated anthraquinones in apothecial disc (C-), chlorinated anthraquinones in exciple (C+ purple in section); Cinereorufa-green pigment usually present in thallus and sometimes in apothecia (K-, N+ violet in section).
Note: a temperate to subtropical species found on a wide variety of siliceous rocks, on horizontal to weakly inclined surfaces, common throughout the Country below the upper montane belt. Earlier records from subalpine-alpine situations (see also Nimis 1993) probably refer to B. psychrophila.
