Rank Reasons
Known from boreal North America and Europe, this species is severely threatened by air pollution in the European half of its global range. North American populations are not (yet) threatened.
Range Extent Comments
"Occurs from approximately 62 degrees N to 48 degrees N latitude on the west coast of North America and follows the boreal forest inland to the Great Lakes. On the east coast it was collected from southern Quebec to Newfoundland. The species is uncommon throughout most of its distribution in North America" (Bowler 1977). Occurs in boreal North America south to OR and western MT (McCune & Geiser 1997). Also in Ontario, the northeastern U.S., and Newfoundland (Brodo et al. 2001). Also in Germany (Schindler 1992, Wirth 1995), coastal Norway, Sweden, and the British Isles (Krog and James 1977, Karstrom 1994, Rolstad et al. 2001).
Threat Impact Comments
Threat is extreme for Europe, low or insignificant for North America. Sensitive to air pollution (McCune & Geiser 1997). Considered to be threatened in their entire distribution area in Europe (Clerc et al. 1992).
