A common species of exposed siliceous rocks and boulder screes in mountain areas. This arctic-alpine lichen can be found in most of the Czech highest mountains along the borders. It is also abundant on screes in the Brdy Hills, in the central part of the country. The range of B. intestiniformis is limited to Europe. Unlike the much rarer B. atrofusca, its medulla contains fumarprotocetraric acid and the thallus has secondary lobes.
