Description: Thallus crustose, episubstratic, bright greenish yellow, epruinose, consisting of 0.2-1(-2) mm wide, scattered or clustered, flat, irregular, angular areoles with pale margins and lower surface, when well-developed forming up to 1-2 cm wide patches, usually starting the life-cycle on the thalli of Diploschistes actinostoma. Cortex paraplectenchymatous, 35-70 µm thick; algal layer continuous; medulla white. Apothecia lecanorine, 0.1-0.4 mm across, immersed in the areoles, 1-4(-8) per areole, with a dark brown, punctiform disc and an evident, not or only slightly raised thalline margin. Proper exciple 15-25 µm wide at base, up to 85 µm wide in upper part; epithecium brownish; hymenium colourless, 120-140 µm high; paraphyses 1.5-2 µm thick at base, the apical cells hardly swollen; hypothecium colourless, up to 35 µm high. Asci 100-200-spored, cylindrical-clavate, the apical dome K/I-, 60-100 x 12-17 µm. Ascospores 1-celled, hyaline, broadly ellipsoid, 3-4(-6) x 2-3(-4) µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV+ orange. Chemistry: cortex with rhizocarpic acid.
