I found some few specimens of this plant epiphytic on 

 Urospora penicilliformis in the upper part of the litoral re- 

 gion. They are 30—42 p. long and 10 — 13 jx thick in the 

 thickest part, bearing almost ripe zoospores in the later halt 

 of August. 



Distribution: Only found at Vardo, rare.
