Description: Thallus mostly inapparent, rarely finely granulose and grey to almost black, growing on the thalli and apothecial margins of Polyozosia populicola. Apothecia lecanorine, small, 0.2-0.8 mm across, with a flat to convex, yellow disc and a thin, concolorous, smooth, finally often excluded margin. Thalline exciple prosoplectenchymatous, with protruding hyphae; epithecium yellow, granular; hymenium colourless, 50-60 µm high; paraphyses mostly simple or sparingly branched in upper part, the apical cells lightly swollen; hypothecium colourless. Asci 8-spored, clavate, with an apical dome which is I+ blue only in the internal, lower part, interrupted in the centre by an I+ paler blue strip, Candelaria-type. Ascospores 1-celled, hyaline, ellipsoid, (12-)13-20(-22) x 5-7 µm. Photobiont chlorococcoid. Spot tests: apothecia K- or K+ reddish-orange, C-, KC-, P-. Chemistry: apothecia with pulvinic acid derivatives.
