220 MAINE AGRICULTURAI, EXPERIMENT STATION. I913. 



In September 1910, a Fusarium was found on glumes of 

 wheat in Maine. The fungus, F VIII, was isolated and has been 

 found to agree in cultural characters with F I from apple. 

 There is less aerial mycelium than in F. roseum, F XVIII, 

 secured from Ohio and spores are produced in large quantities 

 in sporodochia. These masses of spores are orange colored. 

 When apples were inoculated with this fungus it caused as much 

 decay as F I from apple. 



A fungus, F XXXI, isolated from summer squas;h in the sum- 

 mer of 1911 agrees somewhat closely in cultural characters with 

 F II from apple. There are, however, a very small proportion 

 of spores of the obovate type. The spores agree in appearance 

 with those of other fungi which have been described in this 

 paper. This fungus produces such a large proportion of septate 

 spores that it would seem that its classification should be based 

 on these rather than on the obovate spores. It is difficult, how- 

 ever, to separate the fungi which produce spores of these types 

 and place all which show a large proportion of septate spores in 

 the genus Fusarium and those which produce a smaller propor- 

 tion in another genus. 



A species of Fusarium, F XL, was found causing rot of 

 squashes in storage in December, 191 1. This fungus produced 

 much white aerial mycelium with red and yellow color near the 

 medium. The decaying tissues of the squash took on a bright 

 red color. 



A fungus, F XVII, similar to the one from squash was iso- 

 lated from ears of yellow dent corn from Indiana. The growth 

 of this fungus agrees very closely will that of the one from 

 squash when they are grown on the same culture medium. The 

 corn fungus grew rapidly and produced the same effects on 

 squash as the squash fungus when both were used in making 

 inoculations. Neither of these strains has produced many spores 

 in cultures. 



A fungus which agrees in cultural characters with F. oxy- 

 sponim as described by Smith and Swingle * was secured from 

 two sources, Ohio, F XVI, and Vermont, F XV, and these 

 strains have been erown on a number of media. t
