of the host had been made the specimen was submitted to Prof. 

 A. S. Hitchcock and Mrs. Agnes Chase, who reported that the 

 specimen was without doubt cultivated rye. Dr. C. H. Leighty, 

 of the Office of Cereal Investigations, also examined the speci- 

 men and reported that there was no evidence that it could repre- 

 sent a rye-wheat hybrid. 



On account of the importance of rye as a cereal crop in this 

 country the existence of this old collection is considered worthy 

 of note. While the validity of T. Secalis is questioned by some 

 authorities, it seems best for the sake of emphasis to record the 

 collection under the above name. 



Tilletia Holci (West.) Rostrup, Bot. Tids. 22: 256. 1899 



Polycystis Holci Westend, Bull. Acad. Belg. II. 11: 651. 1861. 

 Tilletia Rauenhoffii Fisch. de Waldh. Apergu Syst. Ust. 50. 1877. 



This very distinct species, long known in Europe, has not been 

 reported for North America. It occurs on species of Notholcus 

 and collections have been made by the writer in Oregon an 

 Notholcus lanatus as follows: 



Elk City, August 20, 1914, 1378 ; Yaquina, July 17-20, 1915, 

 3017- 



The sori are obovoid, 1.5-2 mm. in length and occur in the 

 ovaries nearly concealed by the glumes. The spores are chiefly 

 globoid, 24-26 /x in diameter, occasionally ellipsoid, 24-26 by 

 26-30 fi, the wall cinnamon-brown, beautifully reticulated (meas- 

 urements include the colorless reticulations which are 2.5-3 /x 

 high). This smut was very abundant at Yaquina in 1915 and 

 was collected in considerable quantity. All the ovaries in in- 

 fected heads appear to be smutted. 



Entyloma Collinsiae Harkness, Bull. Cal. Acad. Sci. 1 : 40. 



1884 



According to Clinton 3 this species is reported only on Collinsia 

 bartsiaefolia from the type locality, Mt. Tamalpais, California. 

 The following collections made by the writer in western Oregon, 

 besides extending the range add two new hosts.
