Filaments twisted into fine anastomosing ropelike fascicles 3-4 mm. 

 high ; triehomes aeriiginous, slightly torulose, 4.5-5.5/a diam., cells 

 ([uadrate or np to two times as long as the diameter, 5-Sfx long; sheath 

 hyaline, gelatinous and diffluent in the fascicles; terminal cell slightly 

 longer, convex, with small convex calyptra. 



Growing on moist soil and on other plants in a salt marsh. Bay 

 Farm Island, near Alameda. California. Type no. 1598, Gardner. 



Symploca atlantica Collins, Holden and Setchell, Phyc. Bor.-Amer. 

 (Exsicc), no. 1356 (not of Gomont). 



aS'. funicularis differs from S. atlantica in having a diffluent sheath, 

 in having the filaments often tightly twisted into ropelike threads, in 

 having smaller triehomes, less torulose, and with slightly longer cells ; 

 and particularly in the character of the terminal cell, having a small, 

 depressed, convex calyptra covering only about one-third of the end 

 cell, instead of being "depressed conical," as is the case of S. atlantica 

 as described and figured by Gomont (1892, p. 109, 129 Repr., pi. 2, 

 fig. 5). 



Symploca aeruginosa Setchell et Gardner sp. nov. 



Strato expanso, aeruginoso, parce fasciculos 1 mm. altos osten- 

 dentibus; filis 4-4. 5;U. diam., laxe intricatis; trichomatibus maxime 

 torulosis, 3-3. S/A diam. ; cellulis quadratis, cellula terminali rotundata 

 nee capitata nee calyptrata ; cytioplasmate homogeneo, dilute aeru- 

 gineo; dissepimentis obscuris; vaginis tenuibus, hyalinis, strictis, 

 primo levibus demum exteriore asperis. 



Filaments 4— 4.5/x diam., forming an aeruginous stratum of erect, 

 loose fascicles, 1 mm. high ; triehomes decidedly torulose, 3-3. ;V diam. ; 

 cells quadrate, terminal cell much rounded, neither capitate nor calyp- 

 trate ; protoplast homogeneous, pale aeruginous, dissepiments obscure ; 

 sheath very thin, colorless, close, at first smooth, later becoming 

 roughened on the outside. 



Growing on nuul-eovered rocks, near the upper tide limit. St. 

 Michael, Alaska. Type no. 5248.r, W. A. Setchell.

In the Algae of Northwestern America (1903, p. 188). the plant 

 described above as new was referred to Symploca laetcviridis Gomont 

 with the statement that "it certainly seems strange to find a plant,
