This rare lichen is linked to old humid mountain forests of central and east Europe. It prefers bark of young firs. There is no record of the species in western and northern Europe. The species was only once reported from the Czech Republic, from Mt Plechý (Plekenstein) in the Šumava Mts, where it was found on spruce bark (Hilitzer 1924). Subrecently, the species was recorded on beech bark in the cirque of the Roklanské jezero lake (Rachelsee) in the Bavarian part of the Šumava Mts (Printzen et al. 2002). In 2020, it was found also in the Czech part, in a silver fir forest on a S-facing slope above the Boubínský potok brook in the protected area Čertova stráň (Vondrák, unpublished).
