dark olive brown. The filiform basal part of the thallomis 

 sometimes divided and bears two bandshaped branches. 



The plant is litoral, living in pools in the lower part 

 of the zone. It grows somewhat gregarious and occurs only 

 on open coast. The length of the plant is, as at Iceland, 

 generally 10 — 15 cm., but sometimes reaching about 45 cm. 

 Specimens with zoosporangia have been taken in the middle 

 of July. 



Distribution: Found at Kiberg in the neighbourhood of 

 Vardo, in 1882 local but abundant, in 1889 appeared on the 

 same locality only a few small and rather stunted specimens. 

 Also found at Havningberg, very rare, and at Berlevaag, 

 local and scarce.
