Rabenh. Krypt.-Flora, 9, 5, 1: 432, 1936.

Synonyms:

Distribution: N - Lomb, Piem (Isocrono & al. 2004). C - Sar. S - Si (Nimis & al. 1994).

Description: Thallus crustose, thinly episubstratic, smooth to rugulose, continuous to cracked, yellowish white or pale grey. Apothecia perithecioid, completely immersed in semi-globose, up to 2 mm wide, basally constricted thalline warts, with 3-6 pale, punctiform ostioles per wart. Epithecium colourless or pale brown, K-, C-; hymenium colourless; paraphyses branched and anastomosing, poorly coherent. Asci 8-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, with uniseriately arranged spores. Ascospores 1-celled, hyaline, ellipsoid, 30-60 x 15-30 μm, thick-walled. Photobiont chlorococcoid. Spot tests: thallus K+ yellowish or brownish, C-, KC- or KC+ yellow, P- or P+ faintly yellow. Chemistry: coronaton and stictic acid (major), with traces of norstictic acid.

Note: on smooth bark, especially of Quercus and Fagus, probably more widespread. It is included in the Italian red list of epiphytic lichens as “Endangered” (Nascimbene & al. 2013c).
