and in sheltered situations. It bore unilocular sporangia in the 
spring and summer months and in October and November, and 
appears to be able to fructify all the year round. 
var. lubrica has been found epiphytic on Halosaccion ramentaceum 
and had unilocular sporangia in May. 
While the main form is extremely common everywhere along the 
coasts of the Faeroes, var. lubrica has been found only on Bor do: 
Klaksvig (!). 
Elachista flaccida (Dillw.) Aresch. is reported from the 
Faeroes by Lyngbye under the name of Conferva flaccida (Hydro- 
phyt., p. 146): — »Habitat ad littora Faeroensia, Fuco vesiculoso insi- 
dens, haud raro«. The specimens in his herbarium are, however, 
Elachista fncicola. Simmons also (1. c. p. 270) mentions E. flaccida 
»auf Himanthalia lorea bei Thorshavn und auf Fucus vesiculosus 
im Qualbofjord«. The specimens 1 from Kvalbofjord growing on 
Fucus vesiculosus which I have had for examination proved, however, 
to be E. fucicola.

Grows on the receptacles of Himanthalia lorea. 
Found with unilocular sporangia in August and November, 
having, moreover, young plurilocular sporangia in the latter month. 
Doubtless an autumn and winter alga, as I have searched for it in 
vain amongst the material gathered in spring and summer. 
Found hitherto in the following places only: — Svino (H.J.); Syd.: 
Kvalbo (H. S.). 
LEPTONEMA Reinke.

fasciculata (Reinke) Gran, Algevegetationen i Tonsbergfjorden, p. 29.

As I quite follow the opinion expressed by Svedelius in 
»Studier ofver Ostersjons Hafsalgflora«, p. 94, I do not hesitate in 
maintaining Leptonema as a genus though it is certainly closely 
related to Elachista. 
The Fseroese specimens agreed well with Rosenvinge’s de¬ 
scription (1. c.); the vegetative filaments were about 8—9 y broad; 
the fructifying 13—14 y.
