PHAOTHAMNION CONFERVICOLUM, LAGERHEIM, AND ITS 
First RECORDED APPEARANCE IN GREAT BriTain.* By

order Syngeneticee are found in fresh water. G.S. West (1) 
enumerates seven families of this order, and of these only 
four are represented in Great Britain. I was fortunate 
enough to find the only member of the fifth family, the 
Pheeothamniacee, among other Algze collected from the Elf

Swedish botanist G. Lagerheim, who published his descrip-

He had found this Alga in several localities in Sweden as 
an epiphyte on various filamentous Chlorophycee, and as
