Description: Thallus foliose, tightly adnate, deep orange to orange-red, forming up to 6 cm wide, often confluent rosettes, the central parts often dying off in old thalli. Lobes dorsiventral, strongly convex, 0.5-1(-1.3) mm wide end remaining discrete for their entire length, with pale maculae visible at high magnification; lower surface white, rarely with very short, white hapters. Upper and lower cortex mesodermate paraplectenchymatous; medulla white. Apothecia common, zeorine, laminal, substipitate, up to 2.5 mm across, orange to orange-red. Epithecium orange-brown, c. 10 µm thick; hymenium colourless; ; paraphyses simple or sparingly branched, septate, swollen at tips; hypothecium colourless to pale brown. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 9-18 x 5-9 µm, the equatorial thickening (“septum”) (1-)3-5 µm. Pycnidia immersed, slightly darker than thallus. Conidia narrowly ellipsoid, 2-3.5 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: upper surface K+ dark red, C-, KC-, P-, UV+ intensely orange-red. Chemistry: parietin (major), fallacinal, emodin, teloschistin and parietinic acid, corresponding with chemosyndrome A of Søchting (1997).Note: a northern holarctic species found both on well-lit natural rock outcrops and on man-made substrata (especially tiles), mostly in upland areas, descending to lower elevations in continental sites; in strongly eutrophicated situations it can occasionally overgrow bryophytes and plant remains. The species is extraordinarily variable in colour and form, very different individuals often occurring side by side on the same surface.
