A litoral alga, growing on stones, rocks, wood-workj 

 or epiphytic on other algæ, as Fiicaceæ and Halosaccion ra- 

 menfaceam. It appears gregarious and not seldom in great 

 masses, so as to determine essentially the character of the 

 vegetation, for inst. at Sværholt (Vestersiden), KjoUefjord 

 and Finkongkjeilen, and occurs both on open and sheltered 

 coasts. Specimens fnxnished with zoospores have been cel- 

 le cted in June, July and August. 



Bistribution: Common and abundant in most places 

 along the whole coast, but somewhat local.

 water mark in exposed localities. It often appears gregari- 

 ous together with Lyngbya jadertina, and sometimes also to- 

 gether with JJlothrix flacca.

 scarce.
