8i. PucciNiA piMPiNELLAE (Str.) Mart. I, II 

 p. Osmorrhizae (Peck) Cooke & Peck. 



On leaves of Osmorrhiza occidentalis Nutt. : ^^57, I, May 22, 

 1915, Red Butte Canyon, Wasatch Mts. 22^4, II, August 20, 

 191 1, Abajo Mts., San Juan Co., alt. about 2000 m. Exsic. 

 Fungi Utahenses ^55. 



77 and 98. PucciNiA montanensis Ellis 



On Elymus glaiicus Buckley. 2^02, III, Oct. 10, 191 5, Red 

 Butte Canyon, Salt Lake Co. Exsic. Fungi Utahenses 2^4. The 

 host was in a region where it had been surrounded by Hydro- 

 phyllum plants which had borne an abundance of aecia earlier in 

 the year. 



The specimens recorded in the first paper of " Smuts and Rusts 

 of Utah" as No. 98: Puccinia sp. should be referred to Puccinia 

 montanensis. It was suggested in the notes accompanying No. 

 98 that probably these collections (which sometimes have been 

 called Puccinia agropyrina Ellis & Ev.) were connected with the 

 Aecidium on the various species of Hydrophyllum. To test the 

 correctness of this prediction (made in 1910), the writer sent to 

 Dr. Arthur (on May 23, 191 5) a fresh collection of aecia on 

 Hydrophyllum capitatum, and requested that a sowing be made 

 on Agropyron and Elymus. Dr. Arthur's inoculations were suc- 

 cessful, uredinia beginning to show on Agropyron June 7, fol- 

 lowed by telia June 11. 



99. Puccinia atro-fusca (D. & T.) Holway 



The rust designated under No. 99 of the Smuts and Rusts of 

 Utah " as Puccinia sp. should be referred to Puccinia atro-fitsca. 



Another collection was made at the same locality on August 24, 

 1917 (No. 2^48). Both collections were determined by Dr. Kern.
