Loc. It has a continuous distribution along our coast from the Swe- 

 dish frontier in south to the Russian frontier in north, evidently frequent 

 ever\-where along the sea, but not recorded from the fjords. South and 

 west coast: V'asser: Sandøen (Lynge), Stavæm (Norman), Lynger (Lynge), 

 Moster (Havaas and Lynge), Sunde near Luksund, Lygrefjorden, and Stat 

 jHavaas). Northern Nonvay: Rode ^Norman), Salten (Sommerfelt), 

 Tromso (Norm an I, Nordfuglo (Blytt), Alten ( Wahlen berg), Øxfjord (Baur), 

 Honningsvaag (Lynge), Nordkap (Wahlenberg), \'ardø (Havaas), Nassseby 

 and Siaaholmen {Th. Fries), (Lauder Lindsay records the stibobsatra Nyl. 

 from Dovre- (»Jerkin, corticolous and muscicolous«). It is not probable that 

 this could be correct. 



Ditfers from the species in having darker thallus and cilia, more

 maritime plants e. g. Anapiycltia dliaris var. inelanosticta.
