A species with immersed fruiting bodies resembling the common B. aethalea but differing in the yellow-greenish thallus that contains xanthones (C+ orange, UV+ orange). The lichen grows as a pioneer on siliceous stones and rocks. In Europe, it is one of the rarer members of the genus. In the Czech Republic, it has been first found recently, in a single locality in the Křivoklát region (Týřov), where it grows in a single spot, on a sun-exposed andesite rock outcrop.
