Description: Thallus crustose, continuous to finely cracked-areolate, yellowish-grey to green-grey, smooth to finely tuberculate, somewhat shiny, epruinose, sometimes delimited by a thin, unzoned, pale prothallus. Apothecia perithecioid, immersed in 0.3-1.3 mm wide, flattened, basally expanded thalline warts, opening through a darker ostiole (1-4 per wart) which later expands and is surrounded by the torn margin of the wart. Epithecium dark brown to black, K-; hymenium and hypothecium colourless; paraphyses lax, branched and richly anastomosed. Asci 2-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 to subcylindrical, (40-)45-80(-150) x (20-)26-40(-48) µm, with a 1.5-4 µm thick, finely ornamented, 2-layered wall. Pycnidia immersed. Conidia bacilliform, 9-16 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C+ yellow-orange, KC+ yellow, P+ yellow to orange, UV+ yellow-orange to orange-red. Chemistry: 2-chloro-6-O-methylnorlichexanthone and stictic acid (both major), plus various amounts of stictic acid, norstictic acid and constictic acids.
Note: a mainly temperate species found on deciduous trees with smooth bark, especially Carpinus and Fagus, more rarely on deciduous oaks in moist woodlands; most frequent in Northern Italy and in upland areas of the South, but also occurring near the coast in humid situations.
Growth form: Crustose
Substrata: bark
Photobiont: green algae other than Trentepohlia

Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
