45. Urocystis cepulae Frost. Farl. Ann. Rep. Sec. Mass. Board Agr. 



24. 175. 1877. 

 On Alliaceae: 



Allium cepa L. 

 Reported by Underwood (Proc. Ind. Acad. Sci. 1894:151. 1895), as 

 occurring on onions in market, Putnam County, December 1893. Clin- 

 ton (N. Am. Flora 7:57. 1906), also reports this from Indiana. A speci- 

 men in the N. Y. Botanical Garden, collected by Underwood in Indiana, 

 is sterile. The species undoubtedly occurs in northern Indiana. 



46. Urocystis Colchici (Schlecht.) Rab. Fungi Eur. 396. 1861. 



Caeovia Colchici Schlecht. Linnaea 1:241. 1826. 



On Liliaceae: 



Quamasia hyacinthina (Raf.) Britton, Lafayette, Tippecanoe 

 County, May 30, 1907, F. Vasku, May 22, 1916, H. S. Jackson, May 1917, 

 G. N. Hoffer. 



These collections are referred here somewhat doubtfully. The 

 writer is unaware of any record of the occurrence of Urocystis on this 

 host genus though he has made similar collections in Oregon on a western 

 member of the genus.

393. 1856. 



Erysihe occulta Wallr. Fl. Crypt. Germ. 2:212. 1833. 

 On Poaceae: 



Secale cereale L., Plymouth, Marshall County, June 20, 1916, G. A.

 Tippecanoe County, June 1917, H. S. Jackson; Brainbridge, Putnam 

 County, June 27, 1917, G. A. Osner. 



The flag smut of rye is evidently not uncommon, but usually causes 

 little damage.
