The typical form is undoubtedly quite common along the coasts 
of the Faeroes, and has hitherto been found in the following places: — 
Bordo: Kvannesund (H. J.); Str.: Thors- 
havn (!), Gliversnaes (!); Sando: Troldhoved 
(!); St. Dim on (!); Syd.: Frodebo (!), Fa- 
mien (Ostenfeld,!). Var. irregularis has only 
been found on Syd.: Frodebo (!) where it 
grew between tide-marks on Himanthalia 
lorea , associated with the typical form.

A specimen which grew epiphytic 
on Fncus vesicolosus at the exit of a 
stream into Kalbakfjord was peculiar 
on account of a large upper portion of 
the branches having been transformed 
into plurilocular sporangia which ri¬ 
pened and were emptied in basipetal suc¬ 
cession (fig. 73). As I am not aware of 
any previous mention of such a case 
I have illustrated this in fig. 73. The 
plant was otherwise quite normal and 
had the typical, hooked branches. The 
filaments were 8—10 g thick. 
Ectocarpus tomentosus belongs to 
the littoral zone and is quite a common 
epiphyte, especially on different Fucus- 
species, Himanthalia lorea, Alaria, Gi- 
gartina, and in general on larger algae 
growing between tide-marks. It occurs 
both on exposed coasts and in sheltered 
situations and grows luxuriantly even 
in the interior of fjords where fresh¬ 
water runs into the sea. Plurilocular 
sporangia occurred in April, May, July 
and November.

Lyngb. Parts of filaments with the upper 
portion of the branches transformed into 
plurilocular sporangia, a 120:1, 6 330:1. 
This species, which Lyngb ye reports as follows: — »Habitat ad 
insulas Faeroenses, ut in sinu Qualboe Suderoe, imprimis Himanthaliae 
loreae adhaerescens«, is common everywhere along the coasts of the 
Faeroes.
