Description: Thallus crustose, mostly endosubstratic, effuse, greyish white to greenish grey, with or without a dark prothallus, the thalline hyphae I+ blue. Apothecia arthonioid, rounded to angular, up to 2 mm across, level with thallus, with a flat to slightly convex, black, epruinose, rough disc, without a distinct proper margin. Epithecium pale to dark reddish brown, often with bark fragments, K+ reddish; hymenium patchily brownish, up to 150 µm high, I+ red, K/I+ blue, K+ faintly green; paraphysoids branched and anastomosing, sinuous, c. 0.5-1.5 µm thick, the apices without a brown cap; hypothecium brownish, c. 50 µm high, with bark fragments, K+ faintly green. Asci 8-spored, subglobose, semi-fissitunicate, with a large apical dome and a distinct ocular chamber, lacking K/I+ blue structures. Ascospores muriform, with 5-7 transverse septa and 1-3 longitudinal septa in each transverse segment, hyaline, ellipsoid, 26-37 x 12-15 µm. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P-. Chemistry: without lichen substances.
