Description: Thallus crustose, episubstratic, continuous to verrucose, usually up to 0.5 mm thick, whitish to yellowish grey, often delimited by a dark prothallus. Apothecia common, lecideine, black (brown in old or damaged specimens, whitish in rare unpigmented forms), sessile, 0.8-1.8 mm across, with a flat to finally convex disc and a smooth to flexuose, often shiny, >0.1 mm thick, finally excluded proper margin. Proper exciple blue-green in outer part, colourless within, sometimes with crystals dissolving in K; epithecium blackish green, bluish green to dull grey-blue, rarely olive, without crystals; hymenium colourless, not inspersed or inspersed with small oil droplets (L. achristotera), 40-70 µm high; paraphyses easily made free in K, simple, rarely anastomosing or branched in upper part, not capitate; hypothecium brownish orange (K+ bright red-brown) to reddish brown. Asci 8-spored, clavate, with an intensely K/I+ blue tholus penetrated by a faintly amyloid, broadly cylindrical axial mass, and a poorly developed ocular chamber, the wall K/I-, surrounded by a K/I+ blue outer layer, approaching the Lecanora-type. Ascospores 1-celled, hyaline, thick-walled, broadly ellipsoid to ellipsoid, 9-19 x 4.5-10 µm, often biguttulate. Pycnidia dark, immersed. Conidia thread-like, more or less curved. Photobiont chlorococcoid. Spot tests: thallus K- or K+ pale yellow, KC+ yellow, C+ orange, P- or P+ pale yellow (reactions often weak and patchy). Chemistry: arthothelin, granulosin, different xanthones.
Note: this is the commonest epiphytic lichen of Italy, with an extraordinarily wide ecological and altitudinal range, occurring both in natural forests and in urban environments. In NW Europe the species is also saxicolous, especially on brick walls (Aptroot, in litt.). According to Zhao & al. (2015) the species might prove to be heterogeneous. Some records could refer to L. euphorea.
