Description: Thallus crustose, episubstratic, white, areolate, sometimes delimited by a dark prothallus. Medulla white, I-. Apothecia lecideine, black, sessile and constricted at base, with a flat to convex disc and a thin, finally excluded proper margin. Proper exciple brownish in outer part, paler within, the outer hyphae to 6 μm thick; epithecium olive-green; hymenium colourless, c. 60 μm high, I+ blue; paraphyses coherent, the apical cell up to 4 μm wide; hypothecium colourless. Asci 8-spored, clavate, approaching the Lecanora-type, but with a well-developed, weakly amyloid tholus and a relatively narrow, non-amyloid axial mass. Ascospores 1-celled, hyaline, ellipsoid, 8-11 x 4.5-6 μm. Photobiont chlorococcoid. Spot tests: thallus and medulla K-, C-, KC-, P-. Chemistry: miriquidic acid.
