Synonyms: Lecanora tartarea var. alboflavescens (Wulfen) Flot.; Ochrolechia alboflavescens f. subfarinosa Verseghy; Ochrolechia alboflavescens var. plana Verseghy; Ochrolechia papillata (Räsänen) Verseghy; Ochrolechia parella f. papillata Räsänen; Ochrolechia parella var. alboflavescens (Wulfen) Arnold; Ochrolechia tartarea var. alboflavescens (Wulfen) A.

Description: Thallus crustose, episubstratic, 0.3-0.5 mm thick, continuous to rimose or verruculose but not areolate, whitish, cream-coloured, yellow-grey to brown-grey, without a distinct prothallus, sorediate. Soralia usually well-delimited, rounded or rarely irregular, flat to crateriform and then with a distinct thalline rim, rarely convex, 1-2 mm wide, grey to white, the soredia granular, to 150 μm across. Apothecia rather common, lecanorine, 1-3(-4) mm across, with a pinkish brown to brown, sometimes scabrid, usually pruinose, concave to flat disc and a smooth or rarely flexuose, epruinose, sometimes partly sorediate thalline margin. Thalline exciple corticate, the cortex well-developed,
50–75 µm thick; proper exciple weakly developed, not spreading over the
thalline margin; epithecium brownish, C+ and KC+ red; hymenium colourless; paraphyses thin, slender, densely branched and anastomosing; hypothecium colourless, subtended by algae in irregular groups or forming a continuous layer. Asci 2-4-(8-)spored, with thick, amyloid walls, without recognizable apical structures, Pertusaria-like. Ascospores 1-celled, hyaline, ellipsoid, (25-)30-57 x (10-)20-38 µm. Photobiont chlorococcoid. Spot tests: thallus (incl. soredia) K-, C+ yellow, P-; medulla C-. Chemistry: thallus with variolaric acid (major), lichesterinic acid (major), protolichesterinic acid, sometimes with an unknown substance (minor or traces); epithecium with gyrophoric acid (major to minor) and lecanoric acid (minor to trace).
