Orange warts, about -5 mm. diam., prominent on both sur- 
faces of the leaf, scattered or crowded. During summer each 
wart contains a mass of crowded cells, polygonal or rounded, 
variable in form and size, filled with granular orange proto- 
plasm, which break up into globose, ciliated zoogonidia. 
Size, Zoogonidia -003 mm. ; cellules 02-06 mm. diam. 
Parasitic beneath the cuticle of living leaves of dandelion 
(Taraxacum officinale). 
Professor Trail adds to the above description that “in the autumn 
cn lam resting spores are formed singly in the cells of the food 
plant.”
