As may be judged 
from the above descrip-

indeed been much in 
doubt, whether it might 
not be identical with it. 
BATTERS’ species differs 
however, by the erect 
filaments consisting to- 
wards the apices of longer and narrower cells, three or four times as long as broad and 
only 4 or 5y in diameter, while at the base of the filaments the cells are 10—15 x 
in diameter.
