Acolium karelicum (Vain.) M. Prieto & Wedin

A very rare boreal epiphytic lichen, which is generally less common, and also smaller than a similar, related species Acolium inquinans. It is known solely from the bark of spruce and fir. Based on a revision of relevant herbarium samples, Tibell (1971) summarized its distribution in the Czech Republic and confirmed all data previously published in the Catalogue of lichens of the Czech Republic (Vězda & Liška 1999). Historical records of this species in the Czech Republic come from the first half of the 20th century, namely from the Jeseníky Mountains (Mooslehne), Žďárské vrchy Hills (Žákova hora) and the Šumava Mountains (Jezerní stěna, České Žleby, Želnava). Recently, it is known only from a single locality, the cirque of the Plešné jezero Lake, where it was found atypically on the bark of an old solitary sycamore under a rock wall (Palice 1996). Recently, its occurrence was confirmed after more than 20 years. Apparently, it keeps growing on the same tree together with Calicium viride (Palice, unpublished data).
