I92I. No. 7. STUDIES OX THE LICHEN FLORA OF NORWAY. I39 



On Bctiila odorata and sometimes also on mossy rocks, at the inland 

 end of our valleys in subalpine and alpine positions. Usually associated 

 with P. obscnrata which is more common in our countrw Not recorded 

 from W^estern Norwax'. 



var. isidiata var. nov. 



Thallus isidiis longis coralliformibus + dense vestitus. 



Sorfr. Do\re: Kongsvoll (Korrl. et Nvl. Herb. Lieh. Fenn. 209 b), 

 and Knutsho (B. L.I, saxicolous. 



NoRRL. et Nyl. 209 b. agrees well with 1113- specimens, onl}- that they 

 are less coralline. Perhaps transitional stages will be found between this 

 \ar. and P. Bittcri (or P. obscnrata'}), isidia are less valuable as a distinc- 

 tive character than soredia are. Coralline plants were mentioned bv Ny- 

 lander (Flora 1 88 1 p. 537), but not named. 



The Finnish lichenologist Lang who has studied the herb. Ach. in 

 Helsingfors maintains that Bitter misunderstood Acharius' species: Par- 

 iiiclia obscnrata Ach. Syn. p. 218 in herb. Ach. is Bitter's Pariuclia ob- 

 sciirascciis. There is no reason to doubt of this statement.
