512 Report of the Mycologist. 



girdled in various places by a pink fungus, which Mr. J. B. Ellis 

 pronouuces a new species and names Fusarium acuminatum E. 

 & E. Prof. Beach, the Station Horticulturist, informs me that 

 complaints of a similar character have come to the Station in 

 former years and he feels quite certain that specimens of the 

 same fungus were sent him in 1893. As reported, the disease has 

 usually appeared in the center of the field about mid-summer, 

 spreading rapidly for a few days and then disappearing, so that 

 when requests for specimens were sent the reply came that no 

 more specimens could be found. Although not proven by inocu- 

 lation of healthy plants, there is strong evidence that the Fusa- 

 rium is parasitic. It has not been observed on Long Island. 



The following technical description of the fungus by Ellis 

 and Everhart, is copied from the Proceedings of the Academy of 

 Natural Sciences of Philadelphia for 1895, page 441: 



'^Fusarium acuminatum PI & E. Sporodichia gregarious, mi- 

 nute, white at first, then flesh-colored, attenuate-acuminate at 

 each end, 3 to 5, exceptionally 6 septate, not constricted, arising 

 from slightly elongated cells of the proligerous layer, in which 

 respect it differs from the usual type of Fusarium. Quite distinct 

 from F. diphsporum C. & E., which occurs on the same host."
