Habitat. Having never myself found this species in the Polar Sea, I am un- 
acquainted by my own observations as to its habitat within that region. It occurs 
according to Kieren at Nordlanden in the latter part of the summer, epiphytic on Alaria 
esculenta. 
Geogr. Distrib. Known with certainty only from the Norwegian Polar Sea. It is 
reported however also from the eastern Murman Sea. 
Localities: The Norwegian Polar Sea: Nordlanden according to Kieren. 
The Murman Sea: the coast of Novaya Zemlya according to Post. et Rupr. (ep. 
Kyertm. Algenv. Murm. Meer. p. 49).
