In the only place I met with this alga it occurred as 

 a cushion-like cover on Spongomorpha and JRhodochorton 

 BotMi a little above high-water mark, but in a very much 

 exposed locality and, therefore, almost constantly washed 

 over by the waves. The plant was provided with reproduc- 



tive organs in the middle of August. 



Distribution: Only found on the outer side of Homo 

 at Vardo, local and very scarce.
