nitens SCHWEIN. and Puccinia peckiana Howe.) 
The ecidial stage (C@oma nitens Schwein.), the common 
raspberry rust, is abundant throughout the State. The teleuto- 
spores have not yet been found in Minnesota.

Uropyxis SCHROETER. 
The puccinia on Amorpha species (P. amorphe Curt.) has 
here been retained under Schroeter’s genus Uropyxzs. The 
differences between Uvofyxzs and typical Puccinz@ are no less 
than those between Phragmopyxis and Phragmidium. On the 
other hand P. deglubens might be included among the Puccinie 
without much more serious objection than can be raised against 
Puccinia elymi Westd. Puccinia petalostemonis Farlow has a 
slight gelatinous exospore which certainly indicates relationship 
with the Puccznza on Amorpha. Phragmopyxts according to 
Dietel * is more closely related to Uropyxzs than to Phragmz- 
-dium. Ihave seen biseptate spores in Puccinza petalostemonis 
Farl.t The forms on the Leguminose, therefore, seem to 
form a natural group with sufficient distinguishing characters to 
separate them generically from the typical Puccznze. This is 
Schroeter’s genus Uropyxis. Puccinia petalostemonis Farl. 
connects it with the true Pauccne.
