is only known from the Himalayan region at elevations between 3600-4968 m. The morphology of the species varies amongst localities, with samples growing on moss over rock in Yunnan and Sichuan provinces, having broad (1-2 mm) and pale green lobes and samples from meadows at higher altitudes in Xizang Prov. developing narrower (0.5-1 mm) and more branched lobes with a yellowish appearance. These populations, however, share a pruinose thallus, convex lobes with rounded and downwards bent apices, a loose medulla, a well-delimited cortex of the thalline margin and lower cortex and the presence of usnic acid and zeorin.
