Description: Thallus crustose, episubstratic, whitish or yellowish white, very thin, more or less continuous, sometimes granulose-farinose, often inapparent. Apothecia without a thalline margin (but often covered at the base by a thin thalline layer when young), semi-immersed, not constricted at base, (0.2-)0.3-0.5(-0.6) mm across, with a yellowish to orange-brown, concave to flat disc and a thick, raised, more or less pink-coloured, paler proper margin. Proper exciple prosoplectenchymatous; epithecium colourless to pale yellowish brown; hymenium colourless, 80-110 µm high, the hymenial gel I+ blue; paraphyses simple to sparingly branched, c. 1.5 µm thick at mid-level, the apical cells to 3 µm wide; hypothecium colourless or pale yellowish brown. Asci 8-spored, cylindrical to elongate-subclavate, thin-walled, without tholus, the tip drawn out into a conical point, the wall K/I+ blue. Ascospores 3-septate, with at least one septum not parallel with the others, hyaline, narrowly ellipsoid, (9-)10-16(-18) x 4-7 µm. Photobiont trentepohlioid. Spot tests: K-, C-, KC-, P-, UV-.
