hyaline cylindrical bases and 6 germ pores, and in its smaller and very irregu- 

 larly-shaped teliospore heads with only about one-half as many spores to each 

 head as R. lysilomae. 



The writer has carefully examined mounts made from the type collection 

 of R. lysilomae, and found some 30-40 urediniospores intermixed with the 

 teliospores. None of the urediniospores seen was acuminate, all had only 4 

 germ pores which were rather large and prominent. The teliospore heads 

 measured 60-100X65-120/1 in diameter, average for 10 heads 86X92 /a, 

 7-10 cells across, 12-20 peripheral cells and 26-50 cells to a head.
