Description: Thallus crustose, episubstratic, white to cream-coloured, smooth to verrucose and uneven, sometimes delimited by a white prothallus. Apothecia lecanorine, 2-6 mm across, with a pale brown to pale reddish brown, epruinose, slightly concave to flat disc, and a thick, prominent, smooth thalline margin. Cortex of the thalline margin well developed, with a well differentiated medulla; epithecium pale brown, granular, the granules dissolving in K, C+ red; hymenium colourless; paraphyses thin, densely branched and anastomosed; hypothecium colourless to yellowish, underlain by a continuous algal layer. Asci (6-)8-spored with thick, amyloid walls, Pertusaria-type. Ascospores 1-celled, hyaline, broadly ellipsoid, 45-63 x 20-32 µm. Pycnidia pale pinkish brown. Conidia cylindrical, straight. Photobiont chlorococcoid. Spot tests: thallus K+ pale yellow, C+ red, KC+ red, P-; disc of apothecia C+ carmine red. Chemistry: gyrophoric and lecanoric acids.
Note: common and abundant in humid beech forests of the Apennines, rarer in oak forests of Tyrrhenian Italy. Apparently absent from the Alps, this conspicuous lichen probably belongs, together with species such as Parmelia submontana and Physconia venusta, to an ancient, pre-glacial, Mediterranean-montane element which is well worthy of further study. It may be confused with O. tartarea, which contains the androgyna B unknown 3 substance and 2 fatty acids (androgyna B unknowns 1-2 sensu Tønsberg 1992), and has a different ecology.
