A rare arctic-alpine species, linked to siliceous rocks and boulder screes in mountains. This species was first reported from the Czech Republic recently (Palice 1999), as before it had not been distinguished from the very similar and more abundant B. intestiniformis. However, it differs in the chemical substances (medulla contains physodic and protocetraric acids instead of fumarprotocetraric acid) and in the absence of secondary lobes. So far, it has been confirmed only from a few localities in the Krkonoše Mts and one locality in the Brdy Hills (scree under the top of the hill Praha).
