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

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

 everywhere along the sea, but not recorded from the fjords. South and 

 west coast: Vasser: Sandeen (LYNGE), Stavaern (NORMAN), Lynger (LYNGE), 

 Moster (HAVAAS and LYNGE), Sunde near Luksund, Lygrefjorden, and Stat 

 (HAVAAS). Northern Norway: Rede (NORMAN), Salten (SOMMERFELT), 

 Tromse (NORMAN), Nordfugle (BLYTT), Alten (WAHLENBERG), Oxfjord (BAUR), 

 Honningsvaag (LYNGE), Nordkap (WAHLENBERG), Varde (HAVAAS), Naesseby 

 and Sjaaholmen (Tn. FRIES), (LAUDER LINDSAY records the subobscura NYL. 

 from Dovre 2 ( Jerkin, corticolous and muscicolous). It is not probable that 

 this could be correct. 



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

 densely interlaced laciniae, and a more compact, pulvinate thallus. Old 

 herbarium specimens sometimes fade to a greyish-white colour. It has 

 a wider distribution than the type, which is frequently the case with 

 maritime plants e. g. Anaptychia ciliaris var. melanosticta.

Thallus small (up to 2cm.), delicate. Laciniae appressed, discrete, 

 multifid, pinnate or furcate with acute angles and divergent branches, 

 very narrow (0,20,3, rarely 0,5 mm. broad), elongate with crenate, 

 ciliate margins, cilia uncoloured at the base, darkened towards the 

 apices. Thallus even or rugose, without soredia or with some small and 

 inconspicuous apical soredia. Colour white or whitish-grey, under side of 

 the same colour. 



Apothecia with persistent, entire or minutely crenate margin, and 

 epruinose or pruinose disc. Gonidia crowded in the margin, numerous in 

 the medulla, also under the hypothecium; epithecium very insperse (in the
