The fungus from fowl meadow grass, F XXVII, which is 

 identical in appearance in culture with the fungi from the other 

 grasses was used September 2"], 191 1, in making inoculations of 

 16 Enchantress, 6 Lady Bountiful, and 6 Windsor buds. None 

 of these buds decayed. 



The fungus, F XXX, isloated from culms of timothy collected 

 in Maine was used August ii, 191 1, in making inoculations of 

 3 Lady Bountiful, 2 Enchantress and 15 Windsor buds. Ten 

 (lays later 2 Lady Bountiful, i Enchantress and 7 Windsor buds 

 were decayed. Great numbers of spores of the obovate form 

 were found but there was no evidence of the presence of any 

 other fungus. 



November 21, 1911, 27 Enchantress, 15 Windsor, and 7 Lady 

 Bountiful buds were inoculated with F IV from apple. Two 

 weeks later, 22 of the Enchantress, 7 of the Windsor and 5 of 

 the Lady Bountiful buds were rotted. This fungus had been 

 carried in culture for about 2 years but still remained actively 

 parasitic. 



The fungus from corn, F XXXVI, which was designated 

 Fusarium I by Burrill and Barrett was received from Dr. Bar- 

 rett in November, 191 1. December 13, 7 Enchantress, 6 Lady 

 Bountiful and 8 Windsor buds were inoculated using material 

 of this fungus from a potato cylinder culture 12 days old. None 

 of these buds decayed. 



The results of the rather large number of inoculations with 

 fungi from different sources would indicate that a bud rot of 

 carnations very similar to that described as due to S. foae may 

 be caused by a number of different fungi some of which at 

 least are typical species of Fusarium. A number of fungi which 

 produce obovate and septate spores and agree in cultural charac- 

 ters with the carnation bud rot fungus were tested and most of 

 these caused the rot. Three strains which appear to be very 

 closely related to the carnation bud rot fungus in morphological 

 and cultural characters failed to cause the rot. These were the 

 fungus isolated from potato tuber, F IX, the one from fowl 

 meadow grass, F XXVII, which is identical in appearance with 

 the strains from the other grasses and the fungus from corn 

 sent from Illinois by Dr. Barrett. Whether the failure of these 

 fungi to cause the rot was due to the conditions at the time of 

 inoculations or to the fact that these strains were not pathogenic
