Description: Thallus foliose, heteromerous, dorsiventral, broad-lobed, more or less coriaceous, 0.5-0.7 mm thick, usually forming large, up to 35 cm wide, regular rosettes. Lobes 7-20(-30) mm wide, rounded at apex, sinuate at margins, contiguous to slightly overlapping, ivory white to grey-white when dry (turning yellow-brown in the herbarium), green-grey when wet, matt, smooth to warted (pycnidia). Cephalodia globose and partly internal on the lower side, or shrub-like and densely branched on the upper side, the external blue-green-brown or brownish black, up to 2 cm wide. Lower surface white at margins, pale brown over most of the surface, sometimes black in central parts, tomentose, the hairs whitish or brownish 0.15-0.2 mm long, usually with a few, up to 2(-4) mm long, fasciculate, at the base squarrosely branched rhizines. Upper and lower cortex paraplectenchymatous; medulla white. Apothecia rather rare, lecanorine, laminal, sessile and constricted at base, up to 1 cm across, with a concave to flat, glossy brown disc and a smooth, persistent thalline margin. Epithecium brownish; hymenium and hypothecium colourless; paraphyses mostly simple. Asci 8-spored, cylindrical, fissitunicate, the apex of the endoascus with a K/I+ blue ring-shaped structure, Peltigera-type. Ascospores 1-3-septate, hyaline, needle-like, at first hyaline then turning pale yellowish brown, straight to sigmoid, 40-65 x 5-7 μm. Pycnidia laminal, fully immersed into 0.7-1.2 mm wide, conical thalline warts, 0.1-0.2 mm across, the wall 2-layered in upper part, the inner part greyish K+ aeruginose green, the outer part brownish, K-, the ostiole opening as an elongated crack. Conidia bacilliform to rectangular, sometimes swollen at both ends, 3-7 x 1-1.5 μm. Photobiont chlorococcoid in the main thallus, cyanobacterial (Nostoc) in the cephalodia. Spot tests: upper cortex K- or K+ yellow, C-, KC-, P-; medulla K+ pale yellow, C-, KC- or KC+ deep pink, P-. Chemistry: cortex with variable amounts of atranorin (usually in traces); medulla with m-scrobiculin (major) and p-scrobiculin, sometimes substituted by pseudocyphellarin.
