Distribution: C - Tosc, Laz.

Description: Thallus crustose, thinly episubstratic or partially endosubstratic, grey green in shade, pale brown in exposed situations, sorediate, usually without a distinct prothallus. Soralia ochraceous yellow to pale grey-brown, turning cream-coloured in the herbarium, at first punctiform and 0.2-0.7 mm across, later often confluent into 2-3 mm wide, irregularly shaped, flat to convex sorediate patches, with finely granulose soredia. Perithecia rare, scattered, immersed in the thallus with usually only the upper part of visible, sometimes laterally covered by a thalline layer, 0.4-0.6 mm across, pale reddish brown to dark brown, often darker around the ostiole. Exciple colourless to yellowish, c. 30-40 µm thick laterally, becoming thicker (60-70 µm) around the ostiole, of hyphae with thick gelatinized walls, I-, K/I-; hymenium colourless, not inspersed with oil droplets, I+ orange-red, K/I+ blue (mainly the ascus walls); paraphyses simple, (1.5-)2 µm thick, the apical cells not widened; periphysoids simple or with short lateral branches, 20-40(-50) µm long. Asci > 100-spored, cylindrical, tapering towards the apex, the wall thin, I+ pale blue, without a tholus. Ascospores (2-)3-septate, hyaline, ellipsoid-oblong with rounded ends, 7.5-13 x 3-5 µm, without a gelatinous sheath. Photobiont trentepohlioid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a western European, mild-temperate species growing on the trunks of ancient trees, especially Quercus ilex; easy to overlook, being almost always sterile, but certainly extremely rare, and confined to Tyrrhenian Italy. It is included in the Italian red list of epiphytic lichens as “Endangered” (Nascimbene & al. 2013c).
