On naked wood (wood-fences, and the like), on the bark of almost all 

 deciduous trees, even on (Juercus, otherwise so poor, more rarely on Coni- 

 fers, and on the west coast on stones. 



It is one of our most frequent lichens in the zone of the deciduous 

 trees. It ascends to the tree line, but it is rare at these elevations. It is 

 also rare in the more continental parts of our south-eastern valleys. — 

 Nordland is very poorly investigated. But according to Sommerfelt it is 

 'rarissime' in Saltdalen, and this is very probable for it has not been found 

 north of Lofoten. 



Apothecia are very rare in Norway. 



I have never seen quite esorediate specimens in Norway.
