Description: Thallus crustose, thinly episubstratic or poorly visible, formed by whitish granules dispersed among rock crystals. Apothecia sessile and constricted at base, 0.5-0.8(-1) mm across, with a concave, yellowish brown to brown disc, and a thick, prominent, smooth to crenulate proper margin. Proper exciple pale pink to brownish yellow in outer part, colourless within, the lower part 20-35(-50) µm thick, not paraplectenchymatous; epithecium colourless, barely distinguishable from the hymenium; hymenium colourless or yellowish in lower part, up to 165 µm high, inspersed with small yellow droplets; paraphyses coherent, clearly longer than the asci, c. 2 µm thick at mid-level, the apical cells hardly swollen; hypothecium colourless, 40-50 µm high. Asci 8-spored, thin-walled, lacking an apical apparatus or tholus, the wall K/I+ blue. with uniseriately or partly biseriately arranged spores. Ascospores muriform at maturity, with 3-6 transverse septa and 1-2 longitudinal septa, hyaline, ellipsoid, 18-25(-30) x (7-)9-12 µm. Photobiont trentepohlioid. Spot tests: K-, C-, KC-, P-, UV-.
