Besides the typical form of this species I have collected 

 ■ano.ther one, which has a . chlorophyll-green colour. Cp. 

 Schmitz, Chroraatoph. p. 3. Itisreducedin size, thethreads 

 thin and somewhat curled, or often subclavate, forming rafcher 

 ,,interwoven strata on rocks near high-water mark, on exposed 

 places. Only barren specimens have been found. 



The typical form is also litoral, and grows on rocks in 

 the lower part of the zone. I have only met with it in much 

 exposed localities. The length of the threads is generally 

 2 — 5 cm. It is furnished with sporocarps and antheridia ia 



the middle of August. 



Distribution: The typical forin found at Sværholt, com- 

 mon and abundant in the neighbourhood of «Klubben» and 

 at «Vestersiden»; Vardo, local but pretty plentiful. The 

 chlorophyll green form found at Vardo, local and scarcej and 

 at Bugonæs in Sydvaranger, rare.
