I have had but comparatively little material of this species for 

 examination. One of the collections resembled very much No. 322 

 in Hauck and Rickter's »Phykotheka universalis«. 



This species like the preceding was found especially in sheltered 



situations in shallow water and mostly epiphytic on Chordaria 



flagelliformis. Sporangia-bearing specimens were met with in May 



and October. 



Found in the following localities only: — Ost.: Ejde (H. S.), Glibre 

 (H. S.); Str.: Kollefjord (H. S.), Kalbakfjord (H. S., !), Kvalvig (H. J.). 



135. D. Ekmani Aresh., Observationes 3, p. 33; Coilonema Ek- 

 mani Kjellm., N. I., p. 329 (266). 



The Færoese specimens have now and then one or at most 

 only a few lateral branches. 



Found in sheltered piaces in shallow water epiphytic on Scy- 

 tosiphon lomentarius. 



It bore young sporangia in May. 



Found only: — Bordo: Klaksvig (!).

This species grows in the sublittoral zone and occurs down to 

 a depth of at least 10 fathoms. It grows by choice in the open 

 sea, but is also met with abundantly in sheltered situations. It 

 generally grows attached to stones and rocks, but also now and 

 then occurs as an epiphyte on the stems of Laminaria; in sheltered 

 localities it is also frequently found in masses lying detached even 

 on sandy and muddy bottoms as Ro s en vinge points out is the 

 case in Greenland. 



It bore unilocular sporangia at the end of October; while ga- 

 thering it Jonsson saw the spores move. The sporangia, only 

 lately discovered by Kuckuck, and found ahnost simultaneously 

 in some winter-material from Denmark by Rosen vinge, were pre- 

 cisely similar to Kuckuck's ligure (Bemerkungen I, 1894, p. 247).
