The jieiiera of fuiisri which BoUey regards as being of pathogenic in- 

 terest are Collet otriclium, Fusarium, Hclminthosporium, and possibly Mac- 

 rosporium. 



In Circidar No. .■'> of the Purdue T'niversity Experiment Station the 

 statement is made that "tlie average (yield of wheat) on the station farm 

 for the past twenty-five years has been 28.04 bushels per acre." This is 

 nearly thirteen bushels above the average for the state. 



The question naturally arises, knowing the results obtained elsewhere 

 by studies of the internally infecting fungi of seed wheat, whether Indiana 

 varieties taken at random from a single locality may be similarly infected? 



Following the mctliod used liy T. F. Manns, thirty-four different va- 

 rieties of wheat seed were tested by me. I shall summarize briefly the re- 

 sults of the test and hold them tentatively against further studies on both 

 the wheat plants and seed. 



Of the thirty-four varieties, fourteen were free from fungi of any kind. 

 Thirteen of the varieties were found to be infected with a Fusarium. Four 

 of the varieties showed an internal Macrosporiutti. and three varieties 

 .showed both a Fusarium and Mucrosporium infection. 



The meagerness of these data, however, precludes the formation of any 

 dclinitc CDiirliisidiis. Imt docs indicate a t'cL'tiic Held lor studv.
