aslong. At the junction of the pedicel with the spore cells 
we observe the characteristic cyst cells. These are hyaline 
or slightly colored, usually spherical, and average about 12» 
in diameter (for normal spores see figs. 14 and 15) 
fter remaining in water for some time, maceration of the 
Spores is to a certain extent effected, and by slight pressure 
the individual cells are easily separable for examination. It 
is then apparent that R. casst@cola, so far as the arrangement 
of cells is concerned, belongs to the division as noted by Par- 
ker of which R. Zndica is the type; consequently the cells are 
of the vegetation. Water cultures, both slide and cell, then 
manifested no germination after being observed for a number 
of days, To continue the preservation of the material as in 
# natural state, it was simply ‘‘heeled in’’ under a box in an

nally obtained. Slide and cell cultures with both distilled
