This species is litoral and occurs on rocks or in clefts 

 of rocks at high-water mark. It appears to prefer open and 

 exposed coast, hut it also is to be found in rather shelte- 

 red localities. At Kjelmo I met with very slender, almost 

 thread-narrow specimens of f. obconica. This form becomes 

 10 cm. long. The plant has been taken with zoospores in 

 the later half of August. 



Distribution: Pretty common everywhere, except in the 

 inner part of the deep fjords, and at some places abundant. 

 The most common form is f. tortuosa.

E. thallo simplioi. vel inferne sparsim ramoso, utrinque attenuato, 

 tubuloso-compresso, ssepe tortuoso, 20—25 jjl crasso; cellulis 4 — 5 — 6 an-

 quadratis vel rectangularibus. Tab. 2, fig. 10 — 16. 



The name above is given provisionally, as I am not 

 able to refer the species to any known form. It resembles 

 E. micrococea in habit, but in structure it is plainly disting- 

 uished from that species. On the other hand it reminds of 

 certain forms of E intestinalis. It is a small plant, coni*
