A rare semi-parasitic species associated with the conspicuous arctic-alpine crustose lichen Aspilidea myrinii. It has been known for a long time from the subalpine zone on the top of the Sněžka Mt, where it was repeatedly collected: in the 19th century by G. W. Körber (published in exsiccate Lichenes selecti Germaniae as Lecanora badia β milvina) and in the 20th century by A. Vězda (Poelt & Leuckert 1991). Recently it has also been found at the top of the Luční Hora Mt, the Studniční Hora Mt and the Vysoké kolo Mt. In Europe, it grows in high mountains with well-developed alpine vegetation. The lichen is more common in the eastern Alps and western Carpathians. It may also be found in some high mountain ranges of the Balkans (e.g. Prokletije and Pelister; Poelt & Leuckert 1991).
