fourth inch in length and extended one-third to one-half the dis- 

 tance around the pedicel. In many cases they completely encircled 

 the pedicel. Often the spots coalesced, and then a large portion, 

 or even all, of the pedicel was brown. Even with the unaided eye, 

 one could detect a white speck or, more often, a white rift, at the 

 center of each spot. With the aid of a hand lens it could be plainly- 

 seen that the white specks were gelatinous spore masses. The af- 

 fected pedicels almost invariably showed an abundance of the 

 spores. The same was true at Milton two weeks earlier and also 

 at Geneva, on July 13. There was no difficulty whatever in find- 

 ing the spores. 



The presence of the spots on the pedicels caused the fruit to 

 ripen unevenly. Many of the fruits were dwarfed and some of 

 those most severely attacked withered. However, these injuries 

 can not, with justice, be attributed wholly to the spots on the pedi- 

 cels. The premature falling of the leaves, also, had something to 

 do with it. 



We believe this to be the first record of the occurrence of 

 Cylindrosporium padi on the fruit-pedicels of cherry. We do not 

 say positively that such is the case, because we have not made 

 an exhaustive examination of the literature; but it is at least safe 

 to say that the fact ds not generally known, because it is not men- 

 tioned in any of the many accounts examined by us. 



In connection with the appearance of Cylindrospceium on the 

 fruit-pedicels we have observed a spotting of the green fruits which 

 gave cherry growers in the vicinty of Geneva considerable concern 

 last spring. It was first brought to our attention by the Station 

 Horticulturist, Mr. Beach, about June 15. The fruits, which were 

 at that time about the size of peas, showed numerous small, brown, 

 slightly sunken spots. As the fruits grew many of them became 

 somewhat misshapen, seemingly as a consequence of the presence 

 of the spots. The spots enlarged but little and there was no ten- 

 dency to rot. 



In the vicinity of Geneva this trouble was exceedingly common 

 on English Morello and Montmorency Ordinaire and fruit grow- 

 ers were fearful that the crop would 'be injured; but as the cher- 

 ries began to swell and color in ripening the spots seemed to dis- 

 appear so there was little or no loss from it. 



The cause of this spotting is unknown to us. Because of its 

 constant association with Cylindrosporium padi on English Morello 

 at Geneva, Milton and Highland it was at first suspected that it might 

 be due to that fungus. However, no evidence of the presence of any 

 fungus could be found on the spots. Moreover Montmorency Ordi- 

 naire, which was little affected by Cylindrosporium on the foliage, 

 had nearly if not quite as much of the fruit spot as had English 

 Morello. These two facts, particularly the latter, are opposed to the 

 theory that the spots were due to Cylindrosporium padi. (N. Y.
