The distortions produced by this species are confined to the epidermal 
cells, which swell into large pyriform sacks, whose surface is raised in large, 
conical, scattered papille.: To the naked eye the swollen cells look like purple 
glands, which are often so abundant as to nearly cover the surface of the leaves, 
and remind one of the so-called species of Erineum. Each cell contains from 
one to three resting spores which are small in comparison with the host-cell, 
while the contrary is true in S. Myosotidis, in which the galls are somewhat 
similar to those of the present species. The sori in the specimens examined

is a common European weed, and occurs somewhat rarely as an — 
plant in our Athantic States. If the Synchytrium is really, as it seems fo Dé Sih
