Saunders's specimens (No. 352) and have referred a fragmentary 

 specimen from Unga here, but we suspect that they may be only 

 specimens of IridoRa laminarioides f. punicea. They are both 

 sterile but have a parasite, Ghlorochytrium inclusion, which may 

 be the " glandular cells " mentioned by Schmitz . The habit picture 

 of Postels and Ruprecht (1840, pi. 33) does not correspond to 

 any plant accessible to us. The figure of Kuetzing ( 1867, pi. 12) , 

 at least as far as figure d is concerned, might well represent the 

 plant we have known under the name of Sarcophyllis California!, 

 infested with the Chlorochytrium. Our Sarcophyllis, however, 

 belongs clearly to the Dumontiacese, certainly not to the Rhodo- 

 phyllidacese. The description of the cystocarp by Schmitz 

 (1896-1897, p. 372) also doe? not indicate structure sufficiently 

 distinct from that of Sarcophyllis. 



Anatheca furcata Setchell and Gardner sp. nov. Plates 



23, 24. 



Frond arising from a discoid holdfast, cylindrical below (for 

 1-2 cm.), flattened above, and expanding upward to a length of 

 20 cm. and a breadth of 2-3 cm., once to thrice forked; substance 

 thick and firm; color dark red; frond possessing a medullaiy 

 tissue of fine longitudinal hyphal cells, inner cortex of large cells 

 which suddenly become smaller in the outer cortex, while the 

 epidermis is of small, regular, slightly palisade-like cells. Cys- 

 tocarps scattered over the surfaces of the frond, prominent, 

 hemispherical, with apical carpostome. The placenta is central 

 and composed of large cells; the spores are in groups radiating 

 from the placenta on all sides, and are separated from one 

 another by strands of medullary tissue. Tetrasporangia scat- 

 tered in the outer cortex, zonately divided. 



Cast ashore from deep water. West coast of Whidbey Island. 

 Wash.. X.L.Q., No. 633!, and in Collins, Holden and Setchell,

This species might be taken for Callophy I lis furcata f. typica 

 at first glance, so great is the resemblance in habit, color, size, etc. 

 It seems probably a member of the genus Anatheca, and very 

 closely related to the type, A. Montagnei Schmitz, from the coast 

 of Senegambia. We have been unable to examine the type
