Habitat. Either litoral or sublitoral, attached to other alge or to stones, growing 
scattered both on exposed and sheltered coasts. Kienn has collected it with zoospo- 
rangia (and gametangia?) at Nordlanden in August. 
Geogr. Distrib. Known from the Norwegian Polar Sea and Baffin Bay. It is 
uncertain, however, whether the Sphacelaria cirrhosa reported from the west coast of 
Greenland is really the present species and not Sph. arctica. Its maximum of frequency 
is at Nordlanden, this being also the most northern place where it occurs. 
Localities: The Norwegian Polar Sea: Nordlanden common.
