Notes on Some Japanese Uredineae. 


The teleutospores, when young, are light brown in color, and contain one or two ieee globular bodie 
and a few minuts granules. At this stage the processes on the epispore are inere blunt and colorless protuber- 
ances, but at a later.stage they become longer and once or twice bifurcate and hooked at the apex. As the 
spores grow older, they become dark-brown, and the whole contents are broken up into minute granules. The 
pedicel of the spore, when young, is a thin-walled cylindrical body; but when old it becomes thick-walled ; 
leaving a very narrow cavity in the centre, which looks like a longitudinal fissure when seen under the 
microscope. |
