Uredo Castillei^ T. & E. 



No. 5651. July 19, Capitol Wash, Utah, 5000° alt. 



On Cast file ia affinis. 



Amphigenous; in small, round or oblong sori long, 

 covered by the epidermis; spores oval or globose, reddish 

 brown; epispore finely and distinctly aculeolate, rather 

 thick, contents granular, 20-24x15-18 m. 



Synchytriiim fulgens Schroet. 



No. 6012. September 12, Panguitch Lake, Utah, 

 8400° alt. 



On E^ilobiiini adenocaulon. 



This is referred here somewhat doubtfully, as the 

 sporangia are much smaller than in the type, but it does 

 not seem to differ otherwise. 



Synchytrium caricis T. & E. 



Amphigenous, in elliptical or oblong clusters forming 

 distinct, reddish brown spots scattered over the entire 

 leaf; sporangia numerous, globose or oval and often 

 angular, light yellow, 12-15x20-25 m. 



No. 5867a. August 23, Tate Mine, at the head of 

 Bullion Creek, Utah, 1150° alt., on Carex Pyrenaica. 



Erysiphe cichoricearum DC. 



No. 5988. September 4, Circle Valley Canon, Utah, 

 7000° alt. 



On Bigelovia graveolens. 



This form has been so determined by Burrill (N. A. 

 Pyrenomycetes, p. 13), but, as he points out, it differs 

 widely from the type in the greater number of sporidia. 

 In these specimens the appendages are slender, delicate 

 and hyaline; the reticulations of the perithecium are very 

 small, the cell wall thin and delicate; asci numerous, 

 15-20 or more; sporidia uniformly 4-6, much smaller 

 than in the type. The name E. sepulta has been pro- 

 visionally proposed for this form by Ellis and Everhart,
