Distribution: S - Si (Nimis & al. 1994).
Description: Thallus crustose, areolate, parasitic on the grey thalli of C. cretensis, consisting of roundish, up to 5 mm wide islands, which often merge into larger patches, attacking the areoles of the host one after the other. Areoles thin, irregularly angular, pale pinkish-orange, flat, mostly up to 0.5 mm in diam. Thallus parenchymatous, with a loose, indistinct medulla. Apothecia mostly biatorine, but often sitting on a thick algal layer, some algae penetrating in the weakly differentiated exciple, usually sparse, immersed to protruding, mostly solitary in the areoles, 0.2-0.4 mm across, with a flat to slightly convex, pale reddish-orange disc, and an initially thick, then thinner and finally excluded margin of the same colour as the disc. Exciple thin, unclearly radiate-paraplectenchymatous, more or less swollen, with rounded to elongated, 3-7 µm thick cell lumina; epithecium brownish, with a finely granulose epipsamma, K+ red; hymenium colourless, c. 80 µm high; paraphyses robust,1.5-2 µm thick, often apically branched and progressively thicker upwards, strongly conglutinated; hypothecium colourless. Asci (6-)8-spored, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, broadly ellipsoid, the apical wall thicker than the lateral one, and therefore lumina somehow heart-shaped, 10.5-12 x 6.5-8 µm, the septum 2-4 µm thick. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ red, C-, KC-, P-. Chemistry: apothecia with parietin (major), fallacinal, emodin, teloschistin and parietinic acid (minor), corresponding with chemosyndrome A of Søchting (1997).
Note: a well-distinguished calcicolous species growing on Caloplaca cretensis, also known from Turkey, to be sought for throughout the Mediterranean, in coastal situations, wherever the host is found, but certainly not common.
