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

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

 specimens of Iridcea laminarioides f. punicea. They are both 

 sterile but have a parasite, Ghlorochytrimn inchtsiiin, which may 

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

 of Postels and Ruprecht (1<S4(), pi. 33) does not correspond to 

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

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

 plant we have known under the name of SarcophylUs Californica, 

 infested with the Chlorochytrium. Our SarcophylUs, however, 

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

 phyllidaceae. The description of the cystocarp by Schmitz 

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

 distinct from that of SarcophylUs. 



Anatheca furcata Setchell and Gardner sp. nov. Plated 



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 medullary 

 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 gr<)ui)s radiating- 

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

 another by strands of medullary tissue. Tetrasporaugia scat- 

 tered in the outer cortex, zonately divided. 



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

This species might be taken for CaUophyllis fiircata f. typira 

 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 tyi)e, .1. Montagnei Schmitz, from the coast 

 of Senegambia. We have been unal)le to examine the type
