Österr. bot. Z., 67: 279, 1918.

Synonyms:

Distribution: C - Tosc (Craighero 2010), Laz (Craighero 2010), Sar (Craighero 2010).

Description: Thallus crustose, episubstratic, more or less smooth, cracked to verrucose, whitish to yellowish. Apothecia perithecioid, immersed in rounded to irregular, flattened thalline warts, 1-3(-4) per wart, with a punctiform to slightly expanded, 0.1-0.3 mm wide, pale brown disc. Epithecium yellowish, K- or K+ yellow, C- or C+ pink; hymenium and hypothecium colourless. Asci 2-spored, broadly cylindrical, the apex with a broad ocular chamber, the outer sheath K/I+ blue, otherwise K/I-, with an inner extensible layer, Pertusaria-type. Ascospores 1-celled, hyaline, narrowly ellipsoid, 80-110 x 28-50 µm, double-walled, the wall transversally striated, strongly foveolate in the interface between the 2 walls, the inner wall warted. Photobiont chlorococcoid. Spot tests: thallus K+ pale yellow, C+ and KC+ orange (reaction intense in yellowish thalli, less intense in whitish ones), P-, UV+ orange. Chemistry: arthothelin, 6-O-methylarthothelin, granulosin, traces of gyrophoric acid.

Note: this species, described from Portugal and previously known only from the Iberian Peninsula, grows on Juniperus in coastal situations, and is characterised by the presence of artothelin, 6-O-methylarthothelin, granulosin and traces of gyrophoric acid; it probably has a strictly Tyrrhenian distribution in Italy.
