NO. 1 TAYLOR: PACIFIC MARINE ALGAE 247 



oval supporting cell remaining sterile; at maturity the carpospore mass 

 filling the pericarp cavity, largely displacing the upper arachnoid tissue 

 and, a pore having been developed, discharging to the exterior. 



The most obviously related Faucheas of the Pacific coast are F. Sef- 

 feri Howe from Baja California (1911, p. 506) and F. Fryeana Setchell 

 (1912, p. 239) from Washington. From the first these plants differ in 

 their more erect branching, greater width, and more closely placed cysto- 

 carps. From the latter they differ in more erect and less extensive branch- 

 ing, less extreme tapering from the basal segments to the apical, more 

 crowded cystocarps, and a nonfimbriate margin; they are also probably 

 much softer in texture.

 Office Bay, I. Santa Maria, no. 34-375 (cystocarpic, TYPE), 29 Jan. 

 1934. Ibid. J dredged from a rocky bottom at 37-55 meters near an islet 

 in Gardner Bay, I. Espafiola, no. 34-413 (spermatangial), 31 Jan. 1934. 



f. pygmaea n. f .^^^ 



Plants to 3 cm tall, narrowly branched from the base or the lower 

 part undivided or once forked, 3-6 mm broad, commonly marginally 

 closely beset with simple or 1-3 times forked proliferous branches 0.5 mm, 

 rarely to 2.0 mm wide, divaricately branched ; tetrapartite sporangia scat- 

 tered in the cortex, not in recognizable sori, rounded oval, about 22 /* 

 diam., 28 fi long. 



These little plants probably represent a condensed form of the species 

 described above, of which typical sporangial plants were not secured.

Plants repent spreading, crisp in texture, light rose red, at first peltate, 



the blade disciform, round from a short penetrating stalk, later enlarging 



and the disk becoming 3-5 angled with concave sides, the angles attaching
