A boreal lichen, usually forming delimited, pale ochre to (greyish-) brown soralia. The older thalli may form a continuous pulverous coat that shines white-blue under the UV lamp thanks to the presence of sphaerophorin. The bluish-grey or light brown apothecia with vanishing margins are rare.
The species usually grows on acidic bark of both deciduous trees (e.g. Sorbus aucuparia) and conifers, often also on hard deadwood in boreal mountain forests. Its optimal conditions are met in areas with long-lasting snow cover, in mountain spruce forests and raised bogs around the upper tree line. Sometimes it occurs as a monotonous coating on twigs of Vaccinium myrtillus and bark of Pinus mugo. At higher elevations of the Krkonoše Mts, Jizerské hory Mts, Kralický Sněžník Mts, Hrubý Jeseník Mts and Šumava Mts, the lichen may belong to dominant epiphytic lichens. Rarely F. furfuracea occurs also at lower elevations, for example, in cold inverse relic ravines.taxonomic classification: most frequented synonyms:Frutidella pullata, Lecidea pullata, Lecidea amaurospoda
