Description: Thallus foliose, heteromerous, dorsiventral, broad-lobed, more or less closely adpressed, forming up to 10 cm wide rosettes. Lobes becoming imbricate in central parts, otherwise contiguous, thin, smooth, 3-10 mm wide, with rounded apices and indented, sometimes lobulate margins. Upper surface dull grey-green to grey-brown when dry, bright green when wet, smooth and shiny, more rarely becoming wrinkled in central parts, very rarely (known only from Norway) with dendriscocauloid external cephalodia; lower surface almost white, with patches of a fine, brown tomentum. Upper and lower cortex paraplectenchymatous; medulla white, with globose internal cephalodia. Apothecia usually abundant, lecanorine, to 11 mm across, across, with a pale pink-brown to orange-red disc and an inflexed, often warted thalline margin. Epithecium brownish; hymenium colourless; paraphyses mostly simple; hypothecium colourless, subtended by a more or less continuous algal layer. Asci 8-spored, cylindrical, fissitunicate, the apex of the endoascus with a K/I+ blue ring-shaped structure, Peltigera-type. Ascospores 1(-3)-septate, at first hyaline then pale brown, fusiform, straight or slightly curved, 25-47 x (6-)8-11 μm. Pycnidia frequent, with a brown ostiole. Conidia widened at both ends, 4-5 x c. 1.5 μm. Photobiont chlorococcoid in thallus, cyanobacterial (Nostoc) in the cephalodia. Spot tests: upper cortex K-, C-, KC-, P-; medulla K- or K+ pale yellow, C-, KC- or KC+ faintly pink, P-. Chemistry: without lichen substances, or medulla with weak amounts of scrobiculin.
Note: a mild-temperate to humid subtropical species found on old deciduous trees, more rarely on mossy rocks in old, natural, warm-humid forests; probably almost extinct in Northern Italy and along the eastern side of the Peninsula, except in the Gargano Peninsula, and very much declining, locally abundant only in few humid forests of Nouthern Italy. It is included in the Italian red list of epiphytic lichens as “Near-threatened” (Nascimbene & al. 2013c).
