Parme/ia fidiginosa is common in the lowland along the south and 

 west coast and fjords. We have but few stations from the continental parts 

 of Southern Norway. It is evidently rare in Nordland, and north of Lo- 

 foten only recorded from a well exposed warm mountain slope in the in- 

 land end of the Maalselven valley. 



Very rare in alpine positions higher than the tree line (only from 

 Vaarstien, Dovre, famous for its rich flora). 



Apothecia are not common in our countr\'. 



On the whole, Paniie/ia fii/igiuosa is not among our most frequent 

 plants of the Parme/ia o/ivacca tribus.

There is no great difference between Parme/ia fidiginosa and /actc- 

 virens, and I am unable to distinguish between them as proper species, 



Rosenthal states (Untersuchungen p. 443) that the thallus of P. fidi- 

 ginosa is 'matt' (opaque). This is certainly incorrect, for the marginal 

 laciniae which are free of isidia, are almost as nitidous as in the var. /ac- 

 tevirens. The best distinguishing character is the colour: P. fidiginosa has 

 a dark brownish-black colour, var. /actcvircns a brighter castaneous or oli- 

 vaceous or greenish-grey colour. 



var. /actevircns is a corticolous species, it prefers the bark of A/niis 

 and Sorl)its, it is also occasionally found on Picea. According to Malme (Par-
