only having come across piants bearing monospores and refers his 

 piants to Ch. Daviesii, but according to Kjellman (1. c.) they belong 

 to Ch. efflorescens. 



The thickness of the main branches = 7 — 8 n. 



This species has been met with in June only, and then bearing 



monospores; it was found growing in the sublittoral zone epiphytic 



on several algæ in sheltered piaces. 



It has hitherto been found in the following localities only: — Ost.: 

 Fuglefjord on Phijllophora Brodiæi (!), and Ore on Desmarestia aculeata (! .

The specimens referred to this species agree fairly well with 

 Harvey's figure (Phycol. Brit., tab. 314). This species occurs in the 

 sublittoral zone, epiphytic on several large brown algæ, especially 

 on Desmarestia aculeata and on the stalks of Laminaria hijperborea. 

 Found with monospores in May, June and November. 



Does not seem to be coraraon along the snores of the Færoes. Spe- 

 cimens have been seen from the following localities: — Ost: Fuglefjord(!); 

 Str.: Tinganæs(l), Kalbakfjord (H. J.); Sando: Skopen (!). 



In Hydrophyt., p. 129 Lyngbye reports this species from the Færoes, 

 but the specimens in his herbarium in the Botanical Museum, Copen- 

 hagen, which I have examined belong to Ch. uirgatula.

Epiphytic on Alaria esculenta covering its lamina with a short, 

 red-matted growth. Observed with monosporangia in July. 

 Found only on Str.: north of the redoubt of Thorshavn (!).
