BERNT LYNGE. M.-N. Kl. 



Thallus large, to more than 20 cm. in diam. Laciniae imbricate, 

 subappressed to the substratum or more or less ascendent 

 in the centre, rather compact, rarely spreading, multifid, divari- 

 cately furcate. Colour brown or dark brown, lower side white. 

 Laciniae narrower than in the type, 0,5 1, rarely 1,5 mm. broad, cilia 

 dark, brown or brownish-black. 



Thallus thinner than in the type. Upper pseudocortex (20) 40 80, 

 rarely to 100 /LI thick, brownish at the surface (16 20, rarely to 25/0. 

 Hair-like emergences rare or wanting. Gonidia crowded in an 

 incontinuous stratum under the upper pseudo-cortex, also in the medulla. 



Apothecia rare, shortly pedicellate, epruinose, smaller than in the 

 type, 4 5 mm. in diam. Their form and structure, paraphyses, asci, and 

 spores as in the type (spores: 33,242,5^ long, 16 21 [i thick). 



Pycnides and chemical reaction as in the type. 



Hab. On maritime rocks, in the Xanthoria parietina-zone, frequently 

 associated with mosses, one specimen from Northern Norway (Steigen) on 

 Populus. 



Loc. Distributed along our whole coast from the Swedish to the Russian 

 frontier: Yasser (LYNGE), the silurian islands near Kristiania: Naeseen, Nak- 

 holmen, Malmeen (MoE and NORMAN), Lynger (LYNGE). Rare, but not wanting 

 on the west coast, not recorded from the western fjords (HAVAAS). Evidently 

 frequent though not in great quantities, on the shores of Northern Norway : 

 Rede and Gildeskaal (NORMAN), Bode (SOMMERFELT), Steigen (NORMAN), 

 Lofoten (BARTH), Trondenes and Kvaedfjord (NORMAN), Tromse (NORMAN), 

 Skjerve (NORMAN), Nordkap (WAHLENBERG), Berselv in Porsanger (NORMAN), 

 Mortensnes in Varanger (Tn. FRIES). 



There is a certain analogy between Anapt. ciliaris var. melanosticta and 

 Ph. tenella var. marina. Either of them is a maritime plant, nearly related to 

 more continental plants of much more limited distribution. A wider distri- 

 bution of maritime plants than of nearly related continental ones is very 

 interesting from a biological point of view, but less important as a syste- 

 matic character for the reason that we can presume a cause of it to be the 

 more uniform maritime climate. 



Numerous forms of Anapt. ciliaris have been proposed, but with the 

 exception of var. melanosticta they are either stages of age or expressions 

 of individual variation, i) f. agriopa ACHARIUS Methodus p. 255: short,
