Country people distinj^iiish between the useful nnd iiiipf)rtant ( 1. /■//- 

 pestris on one side and tin less useful CI. rangiferina + silvatica on the 

 other side, but they do not distinguish between the two latter species. The 

 'litterary' name 'Rensdyrlav' is only a translation of the latin name Lichen 

 rangiferiiiiis, and never used by the people. Our Norwegian name for 

 earth lichens of a conspicuous size is 'mose' (moss), the name 'lav' (lichen) 

 is used only for the pendulous lichens {Usnea, Alcctoria), and Rangifcr 

 tarandus is called 'rciti or only 'dyr never 'ren or 'rensdyr . 



The following Norwegian names have been noted for CI. rangiferina 

 + silvatica: Rcinsmose (in Gran vin), Kumose and Kvitkaiir (Lom), Graa- 

 mose (Foldalen), Sletniosc and Flatinosc (Tolgen), Kvitmose (common name 

 in S. E. Norway: Torpen, Ringerike).

I am gready indebted to Sandstede for his determinations of m}^ entire 

 material of Cladonia silvatica sensu lat. With every reserve with respect 

 to their specific value I am glad to state their distribution as far as possible. 

 Morphologically I find them very difficult of separation, but Sandstede's 

 determinations reveal interesting geographical differences between them. 



The stations for this species suggest a southern lowland species. 



3. Cladonia tenuis (Flk.) Harm. 



Akcrsli. Bundefjorden: Nesset (B. L.). 

 Vestagd. Mandai: Risobank (B. L.). 



Hord. Møgster (B. L.), Store Kalso (B.L.), Softeland: Mosnuken (B.L.), 

 Sæim (B. L.). 



Sandstede determined my material. The above stations are from the 

 south and west coast, but they are much too few to allow of general 

 conclusions. 



Supposed to be lacking in Arctic Norway.
