3eulata. Hab. in Spirogyra varianti. 
PHLYCTOCHYTRIUM EQUALE 
This species inhabits the cells of Spirogyra, having been found in 
the cells of S. insignis, collected in the pool beyond Forest Home, 
April 17, 1895. The epiphytic sporangium 
and the subsporangial endophytic base are 
about equal in size, being spherical in form 
and about 6 #in diameter. The mouth of the 
sporangium appears to have two small teeth, 
which may be the walls of a short canal. 
From the base of the subsporangial part of 
the plant are several branching rhizoid-like threads. Zoospores 
have not been observed.
