Litoral and epiphytic on other algse, as Bhodomela ly- 

 copodioides, Polysiphonia fastigiata, Cystoclonium purpurascens 

 Ptilota pectinata, Ptilota elegans and Cladophora rupestris. 

 It sometimes appears in larger numbers and almost covers 

 the host plant, for inst. Bh. lycopodioides at Kjollefjord. It 

 prefers open coast and does not enter far into the great 

 fjords, and is, in general, smaller than farther south. I have 

 taken it bearing reproductive organs in the later half of June, 

 in July, and in the first part of August. 



Distribution: Pretty common along the open part of the 

 coast and at some places abundant.
