Description: Thallus crustose, episubstratic, rather thick, rimose-areolate, granulose, grey-brown to brown, sometimes delimited by a black prothalline line. Apothecia punctiform, perithecioid or urceolate, round to ellipsoid, 0.1-0.2 x 0.07-0.1 mm, brown to black, immersed in the thallus, with a flat to slightly convex disc, and a usually indistinct proper margin. Proper exciple much reduced, brown, often poorly evident; epithecium orange-brown, scarcely delimited from hymenium; hymenium colourless, 100-125 μm high, I+ reddish; paraphysoids branched and anastomosing, especially in upper part, 1-1.5(-2) μm thick, the apical cells only slightly larger. Asci 8-spored, cylindrical, fissitunicate, with an amyloid endoascus and a K/I+ blue ring-structure surrounding a small ocular chamber. Ascospores (4-)5-6-septate, hyaline, spindle-shaped, straight o slightly curved, (22-)25-30(-35) x 3-5 μm. Pycnidia black, immersed. Conidia bacilliform, straight, 5-8 x c. 1 μm. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus with confluentic acid.
