Synonyms:
Distribution: N - VA (Matteucci & al. 2015c), Lig (Giordani & al. 2002b, 2009). C - Sar (Giordani & al. 2002b, 2013, Rizzi & al. 2011).
Description: Thallus foliose, heteromerous, dorsiventral, adnate, with irregular to sublinear, 0.1-0.5 mm wide, contiguous to imbricate, 1-2 mm wide lobes which often become densely laciniate in central parts, forming 6-12 cm wide rosettes. Upper surface yellowish green; lower surface pale brown or dark brown-mottled, with sparse, pale brown, simple, 0.3-0.8 mm long rhizines. Upper cortex paraplectenchymatous, with a pored epicortex, the cell walls with Xanthoparmelia-type lichenan; medulla white; lower cortex paraplectenchymatous. Apothecia lecanorine, substipitate, 2-10 mm across, with a brown disc and a smooth thalline margin. Epithecium brown; hymenium and hypothecium colourless; paraphyses simple; hypothecium colourless. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 9-10 x 4-5 µm. Pycnidia common, immersed. Conidia dumbbell-shaped, 5-7 μm long. Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC+ yellowish, P-; medulla K+ yellow-orange, C-, KC+ orange-red, P+ orange, UV-. Chemistry: uppper cortex with usnic acid; medulla with the stictic acid syndrome (stictic, constictic, and norstictic acids, with traces of connorstictic, cryptostictic and peristictic acids).
Note: on siliceous rocks, perhaps more widespread in Mediterranean Italy.
