This is also a coarse variety with elongate, stellate, much 

 branched and discrete iaciniae, continuous from the centre to the 

 circumference. Colour white or greyish-white. Laciniae slightly convex 

 or pale, smooth or a little rugulose, with numerous papillose or branched 

 secondar}- laciniae in the central parts. The long black tomentose 

 rhizinae are distinctly seen between the discrete laciniae. 



The disc of the apothecia is dark, brownish-black, covered by a 

 dense white or bluish-white pruina. Margin usually entire, crenate 

 only in old and coarse plants. 



There are many transitional states between var. acrita and var. anthe- 

 lina with broad, more or less contiguous laciniae. 



Hab. var. anthelina prefers the bark of Populus tremtda and is a 

 faithful companion of that tree. It is also frequently found on the bark of 

 other deciduous trees (not Betiila). It is one of the most frequent Lichens 

 in Norway and is distributed through the whole country from Lindesnes to 

 the Russian frontier. It ascends to 900 — 1000 m. s. m. (as high as 

 its hosts), but it is rare at that elevation. 



Loc. Abundant about Kristiania from innumerable stations in Aker, 

 Baerum, and Asker (N. G. Moe and others), and from the south-eastern 

 lowlands and all the great valleys: Sundvolden (Havaas), Minne, Helgøen 

 (Lynge), Rena (F. Kiær), Sondre Fron (F. Kiær), Dovre (Zetterstedt), 

 Land and Vang (Norman), Kongsberg (Poulsson), Hol (Lynge). Frequent 

 along the south coast : Larvik (Norman), Lyngör (Lynge), and in Western 

 Norway from the coast to the limit of trees: Moster and Granvin (Havaas
