A lichen with tiny black apothecia immersed in the light grey thallus. It resembles the common B. aethalea by its appearance, but differs in the content of gyrophoric acid in the thallus (C+ red) and the characteristic lichenicolous occurrence on thalli of Schaereria fuscocinerea.
The species grows on exposed hard acidic siliceous stones and rocks in the subalpine to alpine zone. It is a widespread but scarce genus member in Europe. Majority of its localities are known from the Alps (Scheidegger 1987). It was also found in the Czech Republic on the Mužské kameny and Polední kameny rocks in the Krkonoše Mts in the past (Kuťák 1926, Scheidegger 1987). Recently it is known from the Žalostná rocks on Mt Keprník in the Jeseníky Mountains.
