Distribution: S - Si (Nimis & al. 1994, Caniglia & Grillo 2005, 2006).
Description: Thallus crustose, endosubstratic or episubstratic, pinkish white (turning white in the herbarium), when well-developed forming an up to 2 mm thick powdery crust, often delimited by a thin, dark prothalline line. Perithecia globose, 0.2-0.4(-0.5) mm across, mostly immersed in the thallus or in the rock (in which case they leave shallow pits when they fall off) or projecting with the blackened upper part. Exciple black and carbonized in upper part, usually pale to colourless in lower part; hymenium colourless, I+ blue-green rapidly turning reddish-brown; paraphyses simple, free, flexuose, not anastomosing, c. 1 µm thick and to 300 µm long, not thickened at apex, closely adhering to the asci; periphyses short-celled, stiff, more abundant and longer (to 45 µm) near the ostiole. Asci 8-spored, unitunicate, narrowly cylindrical, tapering apically, without apical thickening or apparatus, with uniseriately arranged spores. Ascospores submuriform, with less than 10 cells in optical view, hyaline, broadly ellipsoid, (13-)15-18(-20) x 8-10 µm, with a distinct, 3-4 µm thick gelatinous perispore. Pycnidia black, punctiform, with simple conidiophores. Conidia cylindrical, straight, 3-4 x 0.5-0.7 µm. Photobiont trentepohlioid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances. Note: a humid subtropical to Mediterranean-Atlantic lichen found on hard, compact calcareous rocks in sheltered situations.
