Description: Thallus foliose, adnate to loosely adnate, forming 4-12(-20) cm wide rosettes. Lobes elongate, flat to slightly convex, often black-rimmed, separate to weakly imbricate, (0.5-)1-3(-5) mm wide, yellow-green, smooth, shiny, epruinose and emaculate, moderately to densely covered in cylindrical, simple to coralloid isidia. Lower surface black, with simple to furcate, black rhizines. Upper cortex paraplectenchymatous, with a pored epicortex, the cell walls with Xanthoparmelia-type lichenan; medulla white. Apothecia rather rare, lecanorine, substipitate, 2-8 mm across, with a brown, epruinose disc and an isidiate thalline margin. Epithecium brown; hymenium and hypothecium colourless. Asci 8-spored, thick-walled, the apex I+ blue with a wide, divergent axial body, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, (6-)9-10 x (4-)5-6 µm. Pycnidia immersed, black. Conidia weakly dumbbell-shaped, (4-)6-7 x 1 µm. Spot tests: cortex K-, C-, KC+yellowish, P-; medulla K+ yellow turning orange-red, C-, KC+ orange-red, P+ orange, UV-. Chemistry: cortex with usnic acid (major); medulla with stictic acid (major), constictic, cryptostictic and norstictic acids (all minor), connorstictic acid (trace), and sometimes hyposalazinic acid (trace).
Note: on siliceous rocks wetted by rain, including pebbles near the ground, with a wide altitudinal range; restricted to upland areas in Southern Italy, less frequent than the vicariant X. tinctina in the Mediterranean belt.
Growth form: Foliose, broad lobed
Substrata: rocks
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by isidia, or isidia-like structures (e.g. schizidia)
