In the previous report it was stated that no specimens of this smut had 

 been seen. It has since been found to be common and to cause a serious 

 disease of onion sets in certain sections of Lake county. An ample collection 

 was made near Hammond. .July 27, 1920. It has also been observed com- 

 monly on onion sets on the market in Lafayette. The source of these, 

 however, is unknown. A fine specimen collected at Crawfordsville, Mont- 

 gomery Co.. Aug. 10. 1907. by M. B. Thomas, is in the herbai'ium of the 

 Missouri Botanical Garden. No. 132S3. 



40. Urocystis Ornithogali Koern. : Fisch. do Wahlh. Apercu Syst. Ust. 41. 

 1877. 

 Specimens of Urocystis on Quamasia hyaciiitliina (Raf.) Britton were 

 referred in the 1917 list under this number to XJ. Colcliici (Schlecht.) Rah. 

 A more careful study has led to the conclusion that they are more properly 

 referred to T. Oniitliogali. This species has been commonly considered 

 identical with I'. Colcliici but is treated separately by Schellenberg in his 

 excellent monograph of the smuts of Switzerland (Beitriige Krypt. Schweiz 

 -3^:139. 1911). After studying all the European material available the 

 writer is inclined to agree with this view.
