It is a species ecologically similar to B. efflorescens, but markedly rarer. Most of its recent localities are concentrated in forest complexes of southern Bohemia, predominantly in the Šumava Mountains (Printzen & Palice 1999). Apart from Šumava, since 2000 it has been recoded also in the Novohradské hory, Krkonoše, Králický Sněžník, Orlické hory and Javorníky Mountains. The finding of this rather mountain species in the Vyškov region, at low elevation in the valley of the Drahanská vrchovina Highlands (Svoboda et al. 2008), is unique and surprising.
