Orange warts, about *5 mm. in diameter, prominent 

 on both surfaces of leaf blade, scattered or crowded ; 

 during summer each wart consists of a sporangium of 

 crowded spores, polygonal or rounded, but varying much 

 in form and in size (*o2-'o6 mm. diam.), filled with 

 granular orange protoplasm, which often breaks up into 

 globose ciliated zoogonidia ; thicker-walled resting spores 

 formed in autumn singly in the cells of the food plant.
