Description: Thallus crustose, endosubstratic or thinly episubstratic, of very small, dispersed, greenish grey areoles that may coalesce into a more or less continuous, irregular crust. Apothecia zeorine to biatorine, at first slightly immersed, then sessile, 0.2-0.6 mm across, with an initially concave, then flat, orange disc, a thin, often slightly paler proper margin, and a poorly developed, grey thalline margin often present only on the underside of the apothecia. Proper exciple prosoplectenchymatous, 35-40 μm wide; epithecium brownish orange, finely granular, K+ purple-red, C-; hymenium colourless, 45-60 µm high; paraphyses simple or rarely slightly branched in upper part, 1-1.5 µm thick at mid-level, the apical cells swollen, 4-5.5 µm wide; hypothecium colourless, without oil droplets, often subtended by an algal layer. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, 10-13 x 6-6.5 µm, the equatorial thickening (“septum”) 3-4.5 µm, c. 1/3 of spore length. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ purple-red, C-. Chemistry: thallus without lichen substances; apothecia with parietin (major), teloschistin, fallacinal, parietinic acid, and emodin (minor).
