Munroana (Dougl.) Spach. : 1116, Aug. 11, 1908, Gogorza, Sum- 

 mit Co., 6,329 feet. 



ExsiccATi : Fungi Utah. i6y. 



97. PUCCINIA SOLIDAGINIS Peck, III, 



Bull. Torrey Club 11 : 49. 1884. 



On leaves and flowering stems of Petradoria pumila (Gray) 

 Greene, (Solidago pumile Gray) : 22/, June 27, 1903, Wasatch 

 Mts. near Salt Lake City. On leaves and stems of Solidago pul- 

 cherrima A. Nelson: ^jj, July 2, 1903, City Creek Canyon. 

 These specimens differ from the type in their thin walls and the 

 rounded apex. (The host was given as vS. mollis Bartl. in Fungi 

 Utah. 18.) On Solidago trinervata Greene: 441, July 12, 1904, 

 Red Butte Canyon, 5,200 feet. Dr. Arthur successfully sowed 

 germinating spores from this host (collected April 22, 1905, from 

 the same locality as 441) on canadensis. (See "Cultures of 

 Uredineae in 1905 " in Jour. Myc. 12 : 22. 1906.)

98. PUCCINIA SP. II, III, 



On Agropyron caninum (L.) Beauv. : pj7, II, III, Aug. 25, 

 1906, Big Cottonwood Canyon, 8,650 feet. On Agropyron repens 

 Beauv. : j/d, Sept. 3, 1903, Red Butte Canyon. On Agropyron 

 spicatum (Pursh) Scribn. & Smith: 1160, Aug. 28, 1908, Red 

 Butte Canyon. 



There are two Aecidia which have been collected within a few 

 feet of where this Puccinia was afterward found. On June 22, 

 1904, a collection of Aecidium Hydrophylli was made. The 

 leaves of nearby Agropyron plants were yellow with the aecidial 

 spores. At a later date abundant material was taken from these 

 plants. I have scarcely ever collected an Aecidium on Thalictrum 

 without finding Agropyron plants in the immediate vicinity, bear- 

 ing weathered or fresh Puccinia. 



99. Puccinia sp. X, III, 



On Carex sp. : 2016, July 6, near Pharaoh's Glen, Parley's 

 Canyon.
