Type locality: Russia, Magadan, Lynge, 15 Jul. 1921 (O - holotype).

Thallus: parasitic on Aspicilia, irregular in outline, 0.05-0.4-0.8 cm in diam., to 0.2 mm thick, composed of scattered areoles; the areole margin is simple or more often effigurate; surface dusty yellow to pale yellowish orange, occasionally with a blackish-olive tinge at the margin, smooth, matt; hypothallus absent. Apothecia moderately abundant, scattered or in loose groups, developed from own thallus or directly from host thallus, 1(-1.3) mm in diam., sessile, not to slightly constricted, lecanorine to often zeorine; disc plane to weakly convex, dark yellowish-ferruginous red to ferruginous brown; surface structure smooth to fine granulose; apothecial margin initially prominent, thick, not or occasionally flexuose; proper exciple persistent, more bright yellow than disc, while the thalline exciple, which is yellowish orange, is brighter than the proper exciple, but concolorous with the thallus, smooth, occasionally waxy, shining; eventually it becomes excluded; excipulum to 115 µm wide, hyaline; thalline exciple with many algal cells; proper exciple narrow, prosoplectenchymatous, strongly glutinized, hyaline. Hypothecium 150 µm high, of unoriented to anticlinal hyphae with mostly broad lumina, hyaline, oil droplets absent; subhymenium hyaline. Hymenium 65-70 µm high, hyaline; paraphyses not gelatinized, ramified; terminal cells simple or swollen, 3-5 µm wide; subterminal cells to 3 µm wide; epihymenium distinct, yellow to yellowish orange. Asci 65 x 26 µm. Ascospores 8 per ascus, ellipsoid to broadly ellipsoid, 13-16(-17) x 8-10 µm; septum 4-5 µm. (Søchting 2008: 85).
