Habitat. The present species agrees in habitat with the preceding one. It is 
usually fastened to Halosaccion ramentaceum, but occurs epiphytic also on other species, 
as Lhodomela lycopodioides, Polysiphonia arctica, Rhodymenia palmata, Fucus edentatus, 
Desmarestia aculeata, Chatopteris plumosa. In Norway I have found it only at exposed 
points, but at Spitzbergen it lives also in the interior of deep bays. I have taken a 
form globosa in May and June at Spitzbergen. It appears to bear zoosporangia all the 
year round. At Spitzbergen I have seen specimens furnished with such organs in all 
the months of the year with the exception of June and September, in which months 
I had no opportunity of examining it. In January, March, April, and December it was 
very plentifully provided with zoosporangia. On the coast of Norway it has been 
collected with zoosporangia in July and August, on the west coast of Novaya Zemlya 
in June and July. 
Geogr. Distrib. The present species has been found hitherto only in those parts of the 
Polar Sea that are situate north of the Atlantic. It attains its maximum of frequency on 
the north coast of Norway, but it is abundant also in the eastern part of the Greenland 
Sea. The most northern point where it is known to occur is Musselbay on the north 
coast of Spitzbergen Lat. N. 79° 53’. 
Localities: The Norwegian Polar Sea: Nordlanden at Rost; Finmarken, common 
and abundant at Maasé and Gjesveer. 
The Greenland Sea: the north and west coasts af Spitzbergen, pretty common 
and abundant.
