Thallus: crustose, small, areolate over mosses or squamulose on naked loess, yellow-orange, forming spots among other lichens or over mosses, up to 3-15-20 mm diameter. Areoles and squamules rather convex, aggregated, 0.1-0.25-0.5-0.7 mm wide, sometimes well developed with crenulated edges. Apothecia lecanorine to zeorine, 0.2-0.5 mm diameter, disc flat to slightly convex, orange, surrounded by a yellowish orange thalline margin. Cortex paraplectenchymatous 10-14 µm thick, comprising 2-3 cell layers, cells 3.5-4.5 µm diameter. Parathecium thin, prosoplectenchymatous, 22-25 µm thick in the upper part and 10-16 µm thick in the lower portion, with slightly swollen apical cells, up to 3.2-3.7 µm diam. Amphithecium 90-110-120 µm thick, with a paraplectenchymatous cortex. Hypothecium hyaline, with numerous oil drops, 50-70 µm thick. Hymenium 52-62 µm high. Asci 2-4-6 - spored, ascospores 13.5-15-20-21.5 / 7.5-9-11-11.5 µm, septum invisible to very thin 0-1.0-1.5 µm. Paraphyses 2.2-2.5 µm thick, with apical cells up to 3.0-5.0 µm wide. Pycnidia immersed in areoles, with dark orange apices. Pycnospores 2-4 / 1 µm (Kondratyuk et al. 2006: 96).
