This is the same as U. Lupini, Sacc, and is characterized by 

 warty apiculate spores with fragile pedicels. U Lupini, B. & C. 

 has smooth spores and is very different. It is erroneously referred 

 here by Dr. Winter in "Die Pilze," i, 146, on the authority of 

 Thuemen, Myc. Univ. 842. The form on Trifolium has somewhat 

 smaller spores but is not specifically distinct.

 obscured b} r the hairs of the leaf; teleutospores subglobose to ob- 

 long, broadest at, above or- below the middle, 17-25 X 22-45 y. ; 

 epispore thin, of uniform thickness or slightly thickened and pap- 

 illate at the apex ; pedicel fragile. Differs from U. Psoraleaz, Pk. 

 chiefly in longer and narrower spores and more deciduous pedicels.
