a densely matted growth on them. The unilocular and plurilocular 
sporangia which often occur on the same filament were found in 
June and July; but in a gathering from No Iso only plurilocular 
sporangia were observed so on this point they agreed with Pogo- 
ti'ichum hibernicum Johns. 1 , though as a transverse section of the 
filament showed that its median cells were considerably larger than 
those along its periphery, it could not belong to this species. 
This plant was already found by Lyngbye, who writes with re¬ 
ference to its distribution around the Faeroes (l.c.): — »Habitat in utraque 
pagina Laminariae esculentae ad littora Faeroensia, haud vulgarise 
Found in the following places: — Ost.: Ejde (!), Molen (!); Str.: 
Kvivig (!), Velbestad (!), Kollefjord (H. S.), Kalbak (!), Thorshavn (!); Nol- 
so (!); Vaago: Midvaag (!); Syd.: Kvalbo (Lyngbye), Trangisvaagfjord 
(H. S.), Frodebo (!), Sumbo Holm (!). 
POGOTRICHUM Reinke. 
129. P. filiforme Reinke, Atlas deutscher Meeresalgen, p. 62, 
tab. 41, figs. 13—25; Kuckuck, Ueber Polymorphic bei einigen Phaeo- 
sporeen (Festschrift fur Schwendener). 
Grows as an epiphyte on the lamina of Laminaria saccharina 
which it sometimes covers with a dense, matted growth. At the 
base of the filaments the same liyphae-like threads occurred as 
mentioned by Kuckuck (l.c. p.364). 
It was found bearing plurilocular sporangia in May and July, 
but I have not observed unilocular sporangia which Kuckuck 
mentions as occurring on it (1. c. p. 363). 
This species, which is probably fairly common has hitherto been 
gathered from the following places only: — Str.: Thorshavn (!); Vaago: 
Midvaag (!). 
STICTYOSIPHON Kiitz. 
130. S. tortilis (Rupr.) Reinke, Atlas, Tab. 31—32; Rosenv., Gronl. 
Havalg., p. 868. 
Found growing in shallow water in sheltered situations in the 
sublittoral zone. Grows on stones and also frequently epiphytic 
on Chordaria ftagelliformis. It can bear a strong admixture of 
fresh-water. The specimens gathered in June and July which I 
have examined were sterile. 
Found hitherto in the following places only: — Ost.: Strsender (!); 
Str.: Head of Kalbakfjord (!); Syd.: Lobra (!); a closer search would no 
doubt show it to be more commonly distributed.
