Alectoria ochrolcuca is typically a continental alpine plant. In Central 

 Norway it is extremely abundant on dry stations from the tree line and 

 upwards. At this zone it forms extensive 'pastures' together with Cladonia 

 alpvstris, Cetraria uiva/is, and -- though in smaller quantities — Alectoria 

 nigricans and A. divergens. It has here attracted the attention of the country 

 people (Norw. name Blr.ainose, i. e. Blue moss). — In Eastern Norwa}' it 

 also descends to the upper part of the forest zone [Piinis sihester), but it 

 is only on very dry sandy soil, and quite exceptionallv, that it descends 

 so far as to 600 m. s. m. — 



In Western Norway it is less common. Already on the mountains in 

 Upper Hallingdal it does not co\-er the ground as it does in Osterdalen, 

 on Hardangervidda it is only 'not rare', and in Gran\in onl}' found on 

 the highest summits down to 900 m. s. m. as a scarce plant. 



In Northern Norway it is also less common, but it is not so continen- 

 tal as in Southern Norway. North of Lofoten it descends to the level of 

 the sea. In Northern Norway Alectoria nigricans and A. divergens are more 

 common than A. ncliroleiica. To a large extent replaced by A. eiininiiata 

 on the Finmark coast. 



On the mountains of Central Norwa\', Tron, Dovre bzc, fertile speci- 

 mens can be collected in any quantity. Otherwise apothecia are rare in 

 our countrv (see A. cincinnata).
