This coronate-spored grass rust is evidently very common through- 

 out western Oregon on native grasses. It is, however, not common in 

 the Willamette valley on oats. All of the collections on that host are 

 from near the sea coast. 



DeBary (Monat. Akad. Wiss. 211. 1866) was the first to conduct 

 cultures indicating the genetic connection with aecia on Frangula 

 and Rhamnus in Europe. Since that time many European investi- 

 gators have conducted culture experiments (Klebahn, Die Wirtsw. 

 Rostp. 254-262. 1904). 



In America this species has been cultured by Arthur (Bull. Lab. 

 Nat, Hist. State Univ. Iowa 4: 398. 1898; Jour. Myc. 11: 58. 1905; 

 Mycol. 4: 18. 1912) and Carleton (Div. Veg. Phys. & Path. U. S. 

 Dept. Agr. 16: 48. 1899; Bur. PI. Industry, U. S. Dept. .\gv. Bull. 

 63: 15. 1904). 



The only culture made with Pacific coast material was made in 

 1916 in this laboratory under the writer's direction, using telial 

 material on Agrostis exarata sent to the writer from Corvallis by 



G. B. Posey. This was used to inoculate Rhamnus Purshiana, with
