During a three-day field trip to the Gaupne area, Luster kommune, three main localities were visited in search of lichens. A total of 35 lichens or lichenicolous fungi were found to be new to Sogn og Fjordane, most of which are also rare on a national scale. Three species on rocks, Calogaya biatorina, Lecanora gisleriana and L. subaurea, are red-listed and two species, Blastenia monticola and Caloplaca squamuleoisidiata, are new to Norway. Most of the species new to Sogn og Fjordane are calcicolous or prefer siliceous rocks containing high levels of heavy metals. The area around Gaupne is shown to be a previously unknown lichen hot-spot.
