WILSON—PuccINIA PROSTII AND UROMYCES SCILLARUM. 221 
 festalis, but has not been discovered on S. hispanica or on several 
other species of Muscarvt growing in proximity to the diseased 
M. polyanthum. 
Uromyces Ornithogalt, Hazsl. which also occurs on Muscari sp., 
but which has not yet been recorded for Britain, is distinguished 
by the larger teleutospores bearing a hyaline apiculus. 
I wish to express my thanks to Mr. W. B. Grove, who kindly 
confirmed the naming of the two species.
