 grows on similar localities as L. soriferum. 



Distrihution : Only found at Mehavn, very rare.

Sublitoral, growing on varions bottom on a depth of 

 3—15 fathoms water. Most frequently I met it on sandy 

 or clayisli bottom on exposed coasts as well as rather shelte- 

 red ones. It occnrs mostly in thinly scattered individuals, 

 never, as far as I know, in considerable numbers. Tetra- 

 spore-specimens have been colleeted in July and August. 



Distrihution: The species seeras to occure everywhere 

 along the coast. I have tåken it at Lebesby, Mehavn, Hav- 

 ningberg and Vardo, but scarce ; Yadso, pretty plentiful ; 

 Kjelmo, rather scarce.

This species is, in the Polar Sea, one of the largest of 

 the genus. I have seen specimens which had a diameter of 

 about 0.5 m. It is sublitoral and occurs on various depths, 

 though usually on a depth of 10—15 fathoms. But I have 

 also met with large and well developed specimens on a depth 

 of only 3-5 fathoms. It prefers sandy and shingly bottom 

 "and is mostoften met with on sheltered places. Tetraspore- 



r 



specimens have been tåken in June, July and August. 



Distrihution: Found at Kjelmo, pretty plentiful but lo- 

 cal; Mehavn and Kjollefjord, scarce; and at Lebesby, loca|
