been made in Benton County, western Oregon, and are repre- 

 sented in the herbarium of the Oregon Agricultural College and 

 that of the writer. All were made on Trientalis latifolia as fol- 

 lows: Philomath, April 20, 1912, H. S. Jackson and F. D. Bailey, 

 1093; Corvallis, May 19, 1912, F. D. Bailey, 1098, April 8, 1914, 

 H. S. Jackson and F. D. Bailey, 1695. 



All three collections are ample and show both the conidial and 

 chlamadospore stages. In our specimens the chlamadospore sori 

 are confined to the stems and petioles. The conidial stage usually 

 covers the entire upper surface of the leaf, though occasionally 

 occurring in isolated pustular patches.

Cintractia minor (Clinton) comb. nov. 

 Cintractia axicola minor Clinton, Jour. Myc. 8: 143. 1902. 



The writer is of the opinion that this Cintractia is deserving 

 of specific rank. It not only shows constant morphological dif- 

 ferences from Cintractia axicola (Berk.) Cornu but occurs on a 

 different host genus. Seven collections have been examined and 

 the characters found to be constant. All are on Cyperus Grayii 

 Torr. The first collections of which we have any knowledge 

 were made at Atlantic City, New -Jersey, Sept., 1884, by E. W. 

 D. Holway, and Sept. 8, 1884, by J. C. Arthur. A collection 

 was made by J. J. Davis at Sandy Hook, N. J., Aug., 1887, and 

 by J. L. Zabriskie, Aug. 15, 1887. J. B. Halsted also found it at 

 Sandy Hook, N. J., Aug. 15, 1889, and his collection was dis- 

 tributed in Ellis & Everhart's North American Fungi as no. 2423 

 (type of C. axicola minor Clinton). J. C. Arthur made a collec- 

 tion at Rockaway Beach, Long Island, Aug. 14, 1887. The 

 writer also collected this species Oct. 4, 1907, at Selbyville, 

 Delaware. 



In this connection it is worthy of note that a typographical 

 error has been made in the citation of Sandy Hook, New York, 

 as the type locality. The printed label on the specimens dis- 

 tributed in Ellis & Everhart's North American Fungi 2423 does 

 give Sandy Hook, " New York," as the place of collection. This 

 is, however, obviously an error for New Jersey as is shown by
