Norwegian distribution: The species is known from one locality in Oppland and three localities in Nord-Tr›ndelag - Counties:: Op, NT. - Vegetation regions: middle boreal. - Altitude: 80-380 m

World distribution: Pannaria confusa is a European species which is known only from Fennoscandia, from one locality in the Austrian Alps (J›rgensen 1991), and from eastern part of European Russia (Hermansson & Kudryatseva 1995). In Sweden, it is known from some scattered localities from V„rmland to Lule Lappmark (J›rgensen 1991, Santesson 1993), while in Finland it is known from Enonteki” Lappland and the surroundings of ¸bo (J›rgensen 1991)

Ecology: Results. Indicated substrates are schistose rock (2 localities) and Alnus incana (1). Indicated habitats are brook ravines with schistose rock (2), a small brook ravine on marine sediments forested with Alnus incana and Picea abies (1), and the spray zone of a large waterfall (1). Discussion. According to J›rgensen (1991) Pannaria confusa is a species of very humid habitats, often occurring in spruce forests on trees (Alnus incana, Betula sp., Juniperus communis, Picea abies, Salix caprea, and Sorbus aucuparia) or on rock in the spray zone of waterfalls. None of the Norwegian specimens are recorded from Picea abies, but as the species is habitually very similar to Parmeliella parvula, which is a rather frequent species on Picea abies in Tr›ndelag, it may have been overlooked

Threats: Results. Recorded threats are modern forestry by clearcut logging (3) and road construction (1). Development of hydroelectric power is a serious threat at the locality by the river Dokka in Oppland (2771). Discussion. In Sweden, the main threat is development of hydroelectric power and forestry (Aronsson et al. 1995)

Status: Two localities were investigated. It was present in one locality (1705) and apparently extinct in one (1003). No new localities were discovered. There are no protected localities
