Our only exclusively epiphytic Cetraria. It is a boreal-montane to subarctic species, widespread across the Northern Hemisphere. In the Czech Republic, it can be found on birch twigs, for example in peat bogs and boulder screes at higher elevations. It has been reported also from Pinus mugo close to the upper timberline. In a suitable habitat where it is more abundant, it may grow even on twigs of other wooden plants (such as rowan, spruce). The species' name points to a possible occurrence on old worked timber. The Šumava Mts are the only Czech mountains where this lichen is relatively common. In Europe, it is more abundant only in the Alps and the higher parts of the Carpathians. Consequent on the air pollution, C. sepincola declined in the second half on 20th century, similarly as other sensitive epiphytic species.
