On trees [Bctula a. o.), wood, fences, and on mossy rocks. Common 

 in inland districts and very abundant on maritime rocks in S. and W. Nor- 

 way. In N. Norway it is rare on the coast, but more common in inland 

 districts. 



It ascends somewhat higher than the tree line (1200 m.?), but not to 

 the high summits. 



Apothecia are very rare in Norway.
