Mycologia 



Valley, Mendocino Co., California, on Arabis spec. Holway (i) 

 was apparently the first to call attention to the fact that the rust 

 was Puccinia plumharia and the host some species of Phlox or a 

 closely related genus. 



The type collection has been examined through the kindness of 

 Dr. P. Sydow, who loaned all the material with the original label 

 to Dr. Arthur for study. The label reads as follows: ("Uredo?) 

 No. 3. on Cruciferae? spec. Potter Valley, Mendocino Co., Cahf. 

 A. P. 94." This is in the handwriting of Mr. Purpus, who has 

 recently confirmed it from a photograph of the label sent him by 

 the writer. After the figure " 3 " the name Purpusii is written, 

 but by a different hand, very probably Dr. Hennings. This is 

 undoubted type material and consists of several fragmentary 

 stems and leaves of some plant closely resembling Microsteris 

 gracilis. Most of the leaves bear the aecial stage, but one leaf is 

 well covered with telia of the plumbeous sort. The rust is with- 

 out doubt Allodus Giliae. 



Puccinia giliicola P. Henn. Hedwigia 37: 270. 1898; Rab.-Paz. 

 Fungi Eur. 4221. 1901 



Much confusion has existed concerning the exact identity of 

 this species. Hennings published it under the name P. Giliae Ellis 

 & Hark. The type being collected on Gilia calif ornica at Snow 

 Mt., Coast Range, California, about 7,000 ft. Aug.-Sept., 1894 

 (A. Purpus). What is undoubtedly the same rust and host and 

 probably a portion of the same collection has been issued under 

 Rabenhorst-Pazschke, Fungi Europaei et extraeuropaei 4221, 

 and Sydow, Uredineen 1212 but the locality in both of these 

 exsiccati numbers reads. Potter Valley, Mendozo (Mendoc in 

 Sydow Ured. 1212) Co., Calif., instead of Snow Mountain, 

 Coast Range. Whether there was another collection I have not 

 been able to determine but authentic type material kindly loaned 

 by Dr. P. Sydow with the original penciled label written on Amer- 

 ican paper reads " Pilz on Giliaf Spec. . . . Snow-Mt. Coast- 

 Range — Aug.-Sept. 7500-8000 ft." This label was photographed 

 and sent to Mr. C. A. Purpus, Vera Cruz, Mexico, who writes as 

 follows : The label enclosed in your letter was written by me.
