Inthe BoranicaL GazeErTeE, ii. p. 240, a Synchytrium Jonesii 
Peck was described, which grew on Zauschneria Californica and 
Vicia Americana. Through the kindness of Mr. Peck I have 
been able to examine authentic specimens of the parasite on Vicia 
and Zauschneria. Sections in both cases show that spores arise 
from the clavate tips of hyphw which extend into the leaf, and 
therefore the species must be excluded from the genus Synchy- 
ium. It seems to me that the fungus is nearly related to Tuber- 
cularia persiana Ditm., and on the leaves of Vicia it is in com- 
pany with an Zcidium, as is stated in the original description.
