 the mountains, associated with Xaiitlioria lycluica, Physcia tribacia, Par- 

 iiu'lia sulcata a. o. ornithocoprophilous plants. I have never seen Norwe- 

 gian corticolous specimens.

ParmcUa alpicola has only been recorded from hard rocks (e\-en on 

 quartzite). 



It is pronouncedly an alpine plant, found from the highest summits 

 down to the tree line. I have not seen any specimens from the forest 

 zone in Southern Norway, but in Xorthern Norway it descends to the sea 

 level in Finmark and Troms and at least as far south as Lofoten. 



It is a frequent species, in whole Northern Norway and on all the 

 southern mountains.
