THE DISCOVERY OF THE LONG-SOUGHT ALGA, STICTYO- 
SIPHON TORTILIS. 
R. E. SCHUH. 
IN his treatise on the Marine Algae of New England (Rept. of the 
U. S. Commission of Fish and Fisheries for 1879) Dr. Farlow expressed 
surprise that Phloeospora (Stictyosiphon) tortilis (Rupr.) Aresch. had 
not yet been found along our coast. It is frequent along the British 
coast, in the Baltic Sea and Arctic Ocean, along Spitzbergen and 
Greenland, and even in Bering Strait and the Okhotsk Sea. It is now 
my pleasure to report undoubted specimens of this widely distributed 
form from our northeastern coast. It is the habit of the plant to 
break up, thus reproducing vegetatively; and so it happens that, for 
many years, only occasional bits and imperfect specimens had been 
found both in Massachusetts and Rhode Island waters. Indeed, one 
from the latter state received the critical approval of Mr. Frank S. 
Collins, who has also very kindly examined the specimens referred to 
in this note. 
Recently, while sorting some material from Vineyard Sound, 
collected October 12th, 1895, I found splendidly fruited specimens 
with the basal rhizoids still intact. They grew in company with 
Ectocarpus siliculosus and Desmotrichum, and apparently had been 
attached to decayed bits of Chorda. A slide is deposited in the her- 
barium of the New England Botanical Club. Illustrations may be 
found in various standard foreign works on brown algae.
