An epiphytic species typical for natural mountain forests of boreal character described only recently. From the closely related L. betulicola, it may be easily distinguished by the more pigmented margins of fruiting bodies and also microscopically thanks to the content of secalonic acid A in the hypothecium, which turns prominently goldish after application of KOH. The lichen usually grows on hard wood of snags, their branches and on acidic bark of conifers and some deciduous trees (such as rowans), especially in places with long-lasting snow cover. In the Czech Republic, there are only a few records from the Krkonoše and Šumava Mts.
