Sticta silvatica prefers mossy, moist rocks at somewhat shadv places, 

 e. g. in thickets, and the like. It is a common plant on the western coast 

 from Mandai to Stat, it is also found at the western fjords to their inland 

 end. Not recorded north of Stat. In Eastern Norway it retires to the 

 valle3^s where it is but sparingly found. In Western Norway it occasio- 

 nally ascends to 4 — 500 m., in Eastern Norway it is a more subalpine plant.
