Hansen, E. S.: Lichens from Upernavik island, NW Greenland. — Willdenowia 37: 353–362. — ISSN 0511-9618; © 2007 BGBM Berlin-Dahlem. doi:10.3372/wi.37.37125 (available via  http://dx.doi.org/)

167 taxa of lichens are reported from the island of Upernavik. Their associations are briefly indicated and the new species Rhizocarpon subareolatum is described. For 25 taxa the records mean northern range extensions. The lichen flora of the island is comparatively rich in species with a distinct preference for moist habitats, while it is poor in species adapted to more xeric environments.
