The following description of Uredo vitis , Thiim., is drawn up 
from Ravenel’s specimen from Aiken, S. Carolina, and now in the 
Kew Museum : — 
Sori hypophyllous, usually minute, and more or less crowded, 
bright yellow, resembling very minute accidia when seen under a 
pocket lens, due to the elevated marginal border of paraphvses ; 
spores pyriform or broadly elliptical, 18-30 x 15-18 p ; epispore 
thin, minutely verruculose, colourless, contents orange-yellow ; 
paraphyses colourless, cylindrical, slightly curved, 30-55 x 7-9 p. 
Sori rarely larger and solitary ; upper surface of leaf marked 
with spots ; the spores are sometimes attenuated into a short 
pedicel-like base.

conidia densely packed, but individually distinct at the base, 
springing from a dark, cellular basal stratum, elliptic-oblong, 
rather obtuse at both ends, 18-35 X 7-10 g, 2-4, usually 3-sep-
