Paniu'lia oniphalodcs is very variable. The laciniae \"ary from broad 

 and rounded to long and quite linear; they are usually + imbricate and 

 in some plants denselv imbricate: ï. paimifoniiis. The 'typical' colour is 

 brown, but it varies from brownish-black: f. iiigrescciis Harm, to gre3-ish- 

 white: Ï. cincrco-albida Harm. L painiiforniis represents the most important 

 of these formae. It is on the whole more alpine, and more northern than the 

 type. A great part of our Finmark material must be referred to f pauni- 

 formis. 



But all of them are connected with numerous intermediate stages, the}' 

 only represent individual variation. 



Paniielia oinphalodes and its formae are saxicolous plants, in this country 

 only exceptionally found on the trunks of Piuiis silvcster, especially in 

 Northern Norway. It is a ver}- conspicuous plant in the strand lichen 

 vegetation, associated with P. saxatilis, P. stenophylla (in Southern Norway), 

 Raiualiiin angitstissitna, Anaptychia fusca, A. cilinris inelanosticta, and other 

 lichens. It is general and plentiful from the Swedish to the Finnish frontier. 

 — It ascends to very high summits.
