This species occurs sometimes in highly situated rock -pools 



on exposed coasts and sometimes in sheltered localities. 



Fruiting specimens were found in the summer months. 



It is presumabry fairly common around Ihe Færoes, and has been 

 found in the following localities: — Bor do: Klaksvig (H. S.!); Str.: Kolle- 

 fjord (H. S.), Thorshavn (!). 



Cl. fracta (Vahl) Kutz. Rostrup (1. c. p. 87) records this as 

 a common Færoese species, but, nevertheless, it is doubtful if it 

 can be included in the list of the Færoese Flora. There are two 

 specimens in Rostrup's Herbarium which are referred to this spe- 

 cies, one of them is from Thorshavn (gathered Sept. 1867), and 

 determined by Areschoug as »Conf. fracta, proxima«, hence this 

 determination is uncertain. The other is from Bordo (gathered 

 Aug. 1867), and grew on Halosaccion ramentaceum ; on the paper 

 capsule containing this specimen is w ritten in J. Agardh's hand- 

 writing: — »prope C. fractam?«, but a closer examination proved 

 this example to consist mainly of Rhizoclonium riparium in which 

 was intermixed some filaments of an Acrosiphonia. 



In Lyngbye's Herbarium there are no specimens of the Con- 

 ferva fracta y elongata recorded by him in Hydrophyt. (p. 152), but 

 the Museum in Copenhagen contains a specimen on which is writ- 

 ten in Liebmann's handwriting: — »in saxis maritimis ad Thors- 

 havn«, this specimen must, however, undoubtedly have been gathered 

 by Lyngbye. When examined it proved to be a small, stunted 

 Cladophora closely overgrown with a Rhizoclonium riparium var. 

 implexa.

Grows in the shells of Solen, Buccinnm undatum, Cyprina, 



Cardium, Modiola, etc. often associated with Ostreobium and Hgella. 



It was found growing in the sublittoral zone, down to a deplh of 



at least 15 fathoms. Sporangiferous specimens were mel with in Julv. 



This species occurred in many localities, and is doubtless common 

 along the coasts of the Færoes.
