 Bot. Club 34: 459. 1907. 



On leaves and sparingly on fruits of Crataegus rivularis Nutt. : 

 July 22, 191 5, Logan Canyon, Cache Co. Exsic. Fungi 

 Utahensis 22/. Also reported by Dr. O'Gara on the same host 

 from Parley's Canyon, Salt Lake Co. 



On Juniperus scopiilorum Sarg. Collected by Professor Ells- 

 worth Bethel, November 11, 1917, at Gilluly Station (Tucker 

 P. O.), Utah Co. Even at the late date on which this collection 

 was made, a few telial horns still persisted. 



189. Gymnosporangium juvenescens Kern. Ill, Bull. N. Y. 

 Bot. Garden 7: 448. 191 1 



On Juniperus scopiilorum Sarg. Collected by Professor Ells- 

 worth Bethel, November 17, 191 7, in Bullion Canyon near Marys- 

 vale, Piute Co. This species forms large witches' brooms on the 

 cedar trees. The leaves in the fasciations become slender and 

 sharp-pointed Hke those of the young growth. The aecia are 

 found on Amelanchier, but have not yet been reported from Utah. 



190*. Gymnosporangium kernianum Bethel. Ill, Mycologia 



3: 157- 1911 



On Juniperus utahensis (Engelm.) Lemm. : 2^61, July 27. 

 1918, Witbeck's Ranch, near Vernal, Uinta Co. Also collected 

 by Professor Ellsworth Bethel, November 17, 191 7, on the same 

 host, in Bullion Canyon (three miles from Marysvale), Piute Co. 

 This collection consists of only the fasciations made by the rust. 

 These fasciations can be distinguished from those of G. juvenes- 

 cens by the fact that the scales are altered only by becoming 

 smaller instead of reverting to the sharp-pointed form of the 

 younger growth, as they do in G. juvenescens.
