ParDiclia sulcata is especially abundant on Betula and Almis, together 

 with P. physodes and other lichens it often entirely covers the trunks of 

 these trees. It also ver}^ abundant on other trees. Saxicolous at the 

 strand, though less frequently, and also on the mountains (frequentlv), it 

 ascends far beyond the tree line, at least to 1500 m., and perhaps more. 

 It has, however, not been recorded from the highest summits. Also on 

 naked wood, as fences and the like. Very rareh' found on moss. 



Paniiclia sulcata is distributed o\-er the whole country from Lindesnes 

 to Nordkap, from the west coast to the Finnish frontier, frequent or 

 abundant almost everywhere in suitable positions. 



Cummings Lieh. Bor. Amer. 274 {P. saxatilis (L.) Ach.) is P. sulcata. 

 The same is the case with Leighton Lieh. Brit. 203 {P. saxatilis Ach.), 

 and Malbranche Lieh. Norm. 66 (P. saxatilis Ach.).
