On Ranunculus Cymbalaria Pursh, (Oxygraphis Cymhalaria 

 Prantl.) : ^84, I, Sept. 29, 1906, Thistle Junction, Utah Co., 

 5,033 feet. That this is the aecial stage of P. cinerea is proved 

 by Dr. Arthur's culture work for 1908. At the time this collec- 

 tion was made, the Ranunculus was growing in with Sporoholus 

 filiformis (Thurb.) Rydb. The grass was infected with a rust 

 (No. 100 of this hst), and it was thought at the time that there 

 might be some connection between these two. Issued in Fungi 

 Utah, as Aecidium Raniinculacearum DC? On Poa Fendleriana 

 (Steud.) Vasey: 1149, II, III, Aug. 29, 1908, Beck's Hot Springs,
