in Hawksworth & al., Lichenologist, 12: 106, 1980. Basionym: Lecidea flavovirescens var. alpina Schaer. - Lich. Helv. Spicil.: 162, 1833.
Synonyms: Arthrorhaphis citrinella var. alpina (Schaer.) Poelt; Bacidia alpina (Schaer.) Vain.; Bacidia citrinella subsp. alpina (Schaer.) J.R. Laundon; Bacidia flavovirescens var. alpina (Schaer.) A.L. Sm.
Description: Thallus crustose, areolate, forming a compact, 1(-2) cm wide crust, esorediate or rarely sorediate, the areoles bright yellow-green, matt, thick, 0.5-1(-2) mm wide, convex to almost bullate, sometimes crateriform when sorediate, scattered to mostly contiguous, with a farinose epinecral upper layer and a rough surface. Cortex with a 7-10 µm thick epinecral layer; medulla well-developed, white to yellowish, filled with Ca-oxalate crystals insoluble in acetone (visible at least at the base in sections of sorediate areoles). Apothecia rather rare, lecideine, black, located among the areoles and sometimes arranged in rows, rounded, sessile, 0.2-0.7(-1.7) mm across, with an initially concave then flat, smooth disc and a thin, smooth, shiny, finally often excluded proper margin. Proper exciple black and almost carbonized in outermost part, dark grey-green within; epithecium dark grey green to blue-green, K-; hymenium colourless, inspersed with oil droplets, I-; paraphyses lax, slender, branched and anastomosing, not apically thickened; hypothecium pale, the lower part often brownish. Asci 8-spored, bitunicate, cylindrical or narrowly clavate, I-, slightly thickened at apex, with a small ocular chamber. Ascospores (4-)6-11(-15)-septate, hyaline, acicular with pointed ends, thin-walled, (20-)25-45(-60) x 3-4.5(-5) µm, usually not uniseriate in the asci. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV+ orange. Chemistry: rhizocarpic acid and epanorin.
