Litoral, occurring on rocks at low-water mark, or in 

 rock-pools in the upper part of the zone. I also found it 

 cast on shore together with Plilota pectinata, probably from 

 the sublitoral zone. It appears to prefer exposed places. 

 Specimens with zoospores have been collected at the end of 

 June and in the beginning ot July. 



Distribution: Found at Sveerholt, Mehavn and Finkong- 

 kjeilen, rare.
