This alga I only have met with in the litoral region, 

 partly in rock-pools, partly on stenes and rocks in the lo- 

 wer part of the region, often at extreme low-water mark, on 

 open coast as well as on sheltered places. It probably also 

 descends into the sublitoral zone. Specimens found in June 

 and July have heen sterile, but in the middle of August 

 bearing young tetrasporangia. At West-Finmarken I have 

 coUected it with tetrasporangia in the later half of July and 

 in August; in Tromso amt in May, and at Nordland in June, 

 September and February. 



Distribution: Scattered along the whole coast; 

 places pretty common, as KjoUefjord and Pasvig.'
