This is Uropyxis amorphw, Schroter; but aside from the 
peculiar coating of the teleutospore there is nothing to separate 
the species from Puccinia. The uredoform would have been 
considered a good Lecythia, and is much like that of Melamp- 
sora on willows. The teleutosori on the upper side of the leaf 
are compact, the spores crowded. together. On the under side 
the spores are diffusely associated in the sori. 
P. pruni-spinose, Pers. 
Il., I. Hypophyllous. Spots above small, scattered or 
confluent, IT. yellow, IJ. purple; sori scattered, small, rounded, 
teleutosori purplish brown; uredospores oblong or clavate- 
elliptical, smooth, 15-18 by 32-39 »; paraphyses pedicel-like, 
then -swollen at the end and often curved; teleutospores 
deeply constricted, the segments often globose, easily separable 
or more closely united and irregular, strongly echinulate, 21-24 
by 24-39 »; pedicels hyaline, very fragile, about the length of 
the spore; the paraphyses numerous, much enlarged above, 
and brown. 
Scattered, minute, punctiform, spores globose, twin; pedicels very 
short.—Pers. Syn. Fung. p. 226.
