MYCOLOGICAL SECTION. 131 



one of the graminicolous Pyrenomycetes. Fuckel * considers it to be 

 the conidial state of Spliaei'ia recutita, but I do not know that this 

 has been proved. At any rate, it is not improbable that it passes the 

 winter in some snch form, but its summer propagation is effected by 

 tlie conidial spores that I have described. 



ADDITIONAL NOTE ON ANTHRACNOSE. 



{Sphaceloma Ampelinum, De By.) 



Since the report on this subject was in type the following note has 

 been received from Mr. G. Onderdonk, of Nursery, Tex. After re- 

 ferring to the statement of Mr. A. W. Pearson, in Bulletin No. 2 of 

 this Division, to the effect that he had seen no appearance of Sphace- 

 loma ampelinum on any of the ^stivalis class and that it was mostly 

 observed on white grapes, Mr. Onderdonk says: 



Tlie first that I ever saw of this fungus was about the year 1867. This was in tliis 

 county, Victoria, Texas. A few berries of Catawba Avere affected. Soon after it 

 developed freely on some Lenoir clusters, and in 1884 I knew a vineyard in wliich a 

 very promising crop of Lenoir was entirely destroyed by it. The Herbeniont of the 

 same vineyard was entirely exempt. Sometimes for years we saw nothing of the 

 work of this fungus on any variety of the grape, and then there is a sudden ini-oad 

 upon some neighborhood. But the scourge has never become widespread. 



There is one important contrast between our experience and that of observers in 

 New Jersey. In New Jersey none but -white varieties suffered seriously, while in 

 Southern Texas none of the white varieties became affected at all, and the variety that 

 suffered most was the darkest color in our lot of grapes. This leads to a suggestion 

 that there is some condition besides color that governs in the case. Perhaps a mi- 

 croscopic examination may reveal that the structure of the skins of some varieties 

 is more favorable to the propagation of the fungus than in case of other varieties. 



TABULAR LOCAL REPORTS. 



Prof. J. C. Arthur, botanist of the New York Agricultural-Ex- 

 periment Station at Geneva, was engaged to prepare a brief report on 

 the condition of certain crops in his vicinity in respect to the prin- 

 cipal fungous diseases affecting them. At my suggestion he reduced 

 his observations to a tabular form, as given below: A similar table 

 for the vicinity of Washington, and another for certain points in 

 Michigan, are added.
