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 »Pliykotheka 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.).

mani Kjellm., N. I., p. 329 (266). 
The Fseroese specimens have now and then one or at most 
only a few lateral branches. 
Found in sheltered places in shallow water epiphytic on Scy¬ 
tosiphon lomentarius. 
It bore young sporangia in May. 
Found only: — Bor do: 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 Rosenvinge 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 almost simultaneously 
in some winter-material from Denmark by Rosenvinge, were pre¬ 
cisely similar to Kuckuck’s figure (Bemerkungen I, 1894, p.247).
