F. ciihnorum (W. Sm.) Sacc, from winter squash. 



Caused decay of cucumber fruits. 

 F. discolor var. majus nova var., from dent corn. 



F. helianthi Sacc. (sub var.) from apple fruit, potato, summer squash 

 and sunflower. 



Produced decay of carnation buds, also fruits of apple and pear. 

 Negative results with strain from apples on potato tubers. 

 F. metachroum App. and Wr., from wheat. 



Caused decay of apples. 

 F. orthoceras App. and Wr., from cucumber, pea and potato. 



Positive results from inoculation of apple and cucumber fruits, 

 negative upon carnation buds. 

 F. pirinujH (Fries) Sacc, from apple fruit. (F XXXVIII from potato 

 considered identical with F. pirinum by Lewis.) 



Positive results from inoculations upon apple and pear fruits and 

 carnation buds. Negative upon potato tubers. 

 F. poae (Peck) novum nomen, from dent, flint and sweet corn, fowl 

 meadow grass, June grass, quack grass, red top, timothy and potato 

 tuber. 



Positive results from the inoculation of carnation buds with the 

 strains from June grass, quack grass, red top, and timothy. 



Negative results upon carnation buds from the strains from 



fowl meadow grass, dent corn and potato. Strain from sweet 



corn caused decay of cucumber fruit. 

 F. reticulatum Mont., from cucumber, winter squash and wheat. 



Positive results from inoculation of carnation buds and cucumber 



fruits. 

 F. solani (Mart.) App. and Wr., from potato. 



The object of the summary of the inoculation tests is simply 

 to assemble in condensed form the more important data secured 

 by Dr. Lewis regarding pathogenicity and align it as far as 

 possible with the names of the different species to which Dr. 

 Wollenweber has referred the various strains of Fusarium 

 under consideration. Mention should be made, however, of 

 the fact that with the possible exception of F. conglutinans all 

 of the strains studied produced some decay of some varieties 

 of apples. However, only those which gave constant and marked 

 positive results are so credited in the summary. The details of 

 the inoculation tests will be found on pages 239-251.
