Distribution: C - Laz, Sar (Rizzi & al. 2011, Giordani & al. 2013). S - Si.
Description: Thallus crustose, episubstratic, up to more than 1.5 mm thick, rimose-areolate, often delimited by a thin, black prothallus, consisting of contiguous, finally subpeltate-substipitate, pale ochre-brown areoles with a finely rimose surface, forming rounded to irregular patches on the thalli of Lecanora rupicola. Cortex c. 25 µm thick, with an epinecral layer; medulla white, I-. Apothecia lecideine, black, epruinose, adnate to subsessile, scattered to confluent, round to irregular in outline, up to 1.2 mm across, with a flat to finally slightly convex disc, and a slightly glossy, finally often excluded proper margin. Proper exciple dark throughout, (green-black in outer part, reddish brown within), of conglutinate, perpendicularly oriented hyphae, without crystals; epithecium blue-green to finally brownish, up to 10 µm high; hymenium colourless, 55-75 µm high, I+ blue; paraphyses easily made free in K, mostly simple, 1.5-2 µm thick at mid-level, the apical cells 3-4 µm wide; hypothecium ochraceous brown, K+ reddish brown. Asci 8-spored, clavate, with an intensely I+ blue tholus penetrated by a weakly amyloid, broadly cylindrical axial mass, and a poorly developed ocular chamber, Lecidella-type. Ascospores 1-celled, hyaline, ellipsoid, 11-13.5 x 6-7 µm, thick-walled. Photobiont chlorococcoid. Spot tests: thallus K-, C+ orange, KC+ orange, P-. Chemistry: arthothelin, isoarthothelin, thiophanic acid, 2-chloronorlichenxanthone, 2,4-dichloronorlichenxanthone, 2,5-dichloronorlichenxanthone, 5,7-dichloronorlichenxanthone, 5,7-dichloro-3-O-methylnorlichenxanthone,3-O-methyl2,5,7-trichloronorlichenxanthone, plus an unknown, brown, unsoluble pigment,
Note: chemically related to L. asema, but constantly parasitic on Lecanora rupicola.
