from some stations in the forest regions of P'inmark. There is Httle reason 

 to doubt of its presence in the great inland forests of the Trondhjem 

 and Nordland provinces, but the lichen flora of these provinces is almost 

 unknown. 



Fertile onlv from Svanxik ITh. Fries). I have not seen Alectoria oli- 

 vacca Ras. from Norway.

Alectoria bicolor is not rare on mossy rocks in lowland and subalpine 

 regions, and quite common in Western Norway. It ascends to the alpine 

 region above the tree line, it is, however, rare in these elevations, and it 

 does not reach the high summits. — Not recorded north of Dovre.

Alectoria nidulifera is no rare plant in inland forests [Pinus silvester) 

 in Southern Norway, but it has been overseen by former investigators. 

 As yet only few stations from the coast, also rare in Northern Norway.
