Abstract: Tholurna dissimilis, a rare corticolous dwarf fruticose lichen known from Scandinavia since the early 19th century and from western North America since the early 1960s, is confirmed as occurring in eastern Labrador, Canada. The taxon was discovered during a lichen survey of the Makkovik region of coastal Labrador during a botany survey initiated by the Newfoundland and Labrador Wildlife Division in the summer of 2010. The discovery of this rare, unusual lichen ends decades of speculation regarding its occurrence in eastern North America.
