The isidia are coarser than in I Iarm. Lieh. Gall, praec. 490. Lettau 

 also refers Zahlbruckner's Pannclia prolixa var. clcgantitla (1894) to this 

 species; distributed in Krypt. Exsic. \"ind. 666. Zahlbruckner and my- 

 self collected it at the locus classicus in 19 12, the isidia are slightly coarser 

 than Harmand's and some of these plants agree entirely with mine.

ParincUa sitbanrifcra prefers the bark of Almis iiicaiia, but it is also 

 found on other deciduous trees, even on Betula. Occasionally found on 

 naked wood, as wood-fences and the like. More rarely found on Piiiiis 

 Silvester in Southern Norway. In Northern Norway it is not rare as a 

 saxicolous species, in Southern Norway only recorded from Voss as saxi- 

 colous. Saxicolous plants are especially found on way-side stones. P. 

 sitbaiiiifera is evidently a nitrophilous plant. 



Apothecia are unknown from Norway. 



Its distribution follows Aliiiis incana. It is most probably found in 

 the whole of Southern Norway, but it is rare on the west coast; at least it 

 is more common in continental districts. Very abundant in the valleys of 

 Troms fylke; but it makes a sudden stop in Alten. This is evidently due 

 to the fact that Alnns incana is lacking or rare on the coast and in the 

 continental parts of Finmarken east of Alten. 



In spite of its great distribution in Northern Norway P. snbaitri/era is 

 a lowland plant, also in Southern Norway. In reality I have seen no speci- 

 men from subalpine region in Southern Norway, in Granx'in it only ascends
