Description: Thallus crustose, episubstratic, continuous to cracked or verrucose, grey-green to pale yellowish grey, sometimes delimited by a thin white, glossy prothallus, forming large patches to 10 cm in diam., isidiate. Isidia concolorous with thallus, often darker at tips, cylindrical, rarely ovoid or subglobose, usually simple, 0.2-0.5(-1) mm long and 0.1-0.2 mm thick, leaving pale yellowish to white, punctiform scars when shed. Apothecia rare, verruciform-perithecioid, completely immersed in basally constricted thalline warts, opening through a small black pore, 1-4 per fertile wart. Asci 2-4-spored, broadly cylindrical, the apex with a broad ocular chamber, the outer sheath K/I+ blue, otherwise K/I-, with an inner extensible layer, Pertusaria-type. Ascospores 1-celled, hyaline, ellipsoid, 90-160 x 45-70 µm. Photobiont chlorococcoid. Spot tests; thallus and/or medulla K+ yellow often turning dirty red-brown, C-, KC+ yellow, P+ yellow-orange, UV+ yellow-orange. Chemistry: coronaton, stictic acid (major), constictic, cryptostictic, norstictic, hypostictic acids and atranorin (minor or traces). Note: a mild-temperate lichen found on bark of deciduous trees below the subalpine belt. Easily mistaken with the chemically different P. coccodes, and perhaps more widespread.
