regularly cylindrical, is less profusely branched, seems less gelatinous, 

 with fewer or no hairs and has the assimilating cortical filaments 

 shorter and of fewer cells, being 2-4 celled, while in C. divaricata they 

 are 4_6 e ven more celled. The aspect of C. dissessa is that of a coarser, 

 less abundantly branched, plant than is that of C. divaricata. 



35. Analipus Kjellm. 



Thallus composed of an expanded, more or less deeply lobed, 

 pseudoparenchymatous, sterile, basal portion attached to the sub- 

 stratum by numerous, unicellular or multicellular, rhizoidal filaments, 

 and giving rise above to simple, more or less cylindrical, solid or 

 fistulous, fertile fronds; fertile fronds composed of a dense mass of 

 pseudoparenchymatous cells with a few chromatophores giving rise 

 on the surface to short, densely congested, cortical, assimilating fila- 

 ments and to numerous zoosporangia ; gametangia unknown.

The type and only known species of the genus is A. fusiformis 

 from Bering Island. 



Analipus fusiformis Kjellm. 



Fertile fronds 2-6 cm. high, 1-3 mm. diam., one to several arising 

 from the upper side of the same horizontal base; the sterile base pro- 

 fusely and deeply lobed, terminal lobes rounded and blunt, attached 

 by short, somewhat branched, monosiphonous hairs; cortical filaments 

 of fertile fronds 3-5 cells long, elavate, with enlarged, rounded, 

 terminal cell; zoosporangia arising from the base of the paraphyses, 

 globose to ellipsoidal, 35/* long, 25/x broad (fide Kjellman), up to 65/x 

 long. 



Growing on rocks. St. Paul Island, Bering Sea, Alaska.

The material reported here seems to be almost identical with that 

 found at Bering Island, the type locality, and reported by Kjellman. 

 The zoosporangia are somewhat larger than the dimension given by 

 Kjellman. some being as long as 65fi. 



Analipus seems to belong to the Chordariaceae as we have limited 

 it, and we have been able to assure ourselves that the method of growth 

 in length is subapical and, consequently, that the agreement with
