Description: Thallus crustose, thinly episubstratic, continuous to (rarely) finely cracked, whitish to pale grey or cream-coloured, smooth to tuberculate, sometimes delimited by a pale prothallus, forming up to 10 cm wide patches. Apothecia perithecioid, completely immersed in scattered, basally restricted, 1-3 mm wide, semiglobose fertile warts with an often slightly flattened apex, opening through a punctiform, black ostiole (2-15 ostioles per wart). Epithecium dark brown to black-brown, K-; hymenium colourless; paraphyses lax, branched and richly anastomosing; hypothecium colourless to pale yellow. Asci 2-spored (very rarely a few of them 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, (120-)140-230(-270) x (35-)40-80(-90) µm, with a 7-15 µm thick, 2-layered, smooth wall, the apices to 28 µm thick. Pycnidia rare, immersed. Conidia needle-like, 7-10 x 0.5-0.7 µm. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-, KC+ yellow, P+ orange-yellow, UV+ pale orange. Chemistry: 4,5-dichlorolichexanthone and stictic acid (major), constictic and norstictic acids (minor).
