the data on the original specimen in the Ellis collection at the 

 New York Botanical Garden, which was evidently communi- 

 cated to Mr. Ellis by Dr. Halsted. The distribution by states as 

 now known to the writer is New York, New Jersey and Delaware. 



This species under discussion is easily separated from Cin- 

 tractia axicola by the smaller spores, which measure 10-13^, 

 while in C. axicola the spores are 12-18 p. The effect upon the 

 host is similar. 



Sorosporium Saponariae Rud. Linnea 4: 116. 1829 , 



This is the type species of the genus and has been reported 

 from North America, so far as can be learned, only from Utah, 

 on Stellaria Curtisii Rydb. and Silene MenziesU Hooker, by Gar- 

 rett, 6 and from New York on Cerastium arvense by Peck. 7 The 

 writer has recently examined specimens as follows, adding three 

 new hosts for North America and extending the distribution to 

 include Nevada and Colorado : 



On Cerastium oreophilum Greene, Golden, Colorado, May, 

 1914, E. Bethel. 



On Silene Watsoni Robinson, near Mt. Rose, Nevada, July 21, 

 1918, N. F. Petersen, 36^. 



On Stellaria Jamesiana Torr., Golden, Colorado, June 12, 1905, 

 E. Bethel. 



Thecaphora Iresine (Elliott) comb. nov. 



Tolyposporium Iresine J. A. Elliott, Mycologia 11: 88. 1919. 



In the fall of 1918 Mr. C. C. Deam, of Bluffton, Indiana, sent 

 to the writer, among other parasitic fungi, an interesting smut on 

 Iresine paniculata (L.) Kuntze, which he had collected Sept. 21, 

 1918, in a dried up wooded slough about one half mile south of 

 Half Moon Pond, which is about ten miles southwest of Mount 

 Vernon in Posey County, Indiana. (Deam, no. 26651.) 



This was at once recognized as a species of Thecaphora and 

 an examination of the literature revealed that only one species 

 of this genus was known in North America on Amaranthaceae,
