Description: Thallus crustose, thinly episubstratic, greyish green, minutely granulose to farinose, sometimes inconspicuous. Apothecia biatorine, yellowish, reddish brown or orange-brown, 0.1-0.3 mm across, with a flat to convex disc and a usually paler, often finally excluded proper margin. Proper exciple paraplectenchymatous, colourless to yellowish brown near the hypothecium; without crystals; epithecium not well differentiated from the hymenium; hymenium colourless, 35-50 μm high, I+ blue; paraphyses branched and anastomosing, 1-1.2 μm thick at mid-level, the apical cells slightly swollen, up to 3-4 μm wide; hypothecium reddish brown. Asci 8-spored, clavate, with a K/I+ blue apical dome containing a darker blue, tubular ring-structure, and an amyloid coat, Byssoloma-type. Ascospores 5-7-septate, hyaline, ellipsoid, slightly tapering at one end; (16-)18-21(-25) x 2.5-4 μm. Pycnidia violaceous black, slightly immersed, the inner wall dark violaceous, K+ purplish. Conidia colourless, clustered as a whitish drop in the ostiole, oblong to obpyriform. Photobiont chlorococcoid. Spot tests: thallus and apothecia K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.

Note: a humid subtropical species described from Caucasus and also reported from the Pyrenees, known from a single locality in Italy, a very humid gorge near the Tyrrhenian coast. It is included in the Italian red list of epiphytic lichens as “Critically Endangered” (Nascimbene & al. 2013c).
