An inconspicuous microlichen with immersed, pale yellow to ochraceous apothecia. It is easily recognizable microscopically due to hundreds of small halonate spores in each ascus. It occurs in two distinct habitats: on shrubs in the subalpine belt, at places with long-lasting snow cover above the upper treeline and on wet weathered nutrient rich bark of deciduous trees, mainly beeches, in old-growth forests (Vězda 1968). Rare in central Europe. In the Czech Republic so far known from two forest sites in the Šumava Mts.
