REPORT OF THE MYCOLOGIST. 



By F. C. Stewart, M. S. 



During the past year the mycologist Las been occupied chiefly 

 with the study of carnation rust and methods of combating it. A 

 preliminary report upon these investigations will be published in 

 bulletin form in the near future. A bulletin on potato diseases ia 

 also nearly finished. 



Considerable time has been devoted to collecting and mounting 

 plants ; both flowering plants and fungi. It is the desire of the 

 mycologist to build up the herbarium as rapidly as possible, particu- 

 larly in the group of parasitic fungi. 



Addresses were delivered before Farmers' Institutes at the follow- 

 ing places in south-eastern New York: Southampton, Soutliold, 

 Mattituck, Huntington, Mineola, Riverhead, Farmingdale, Jamaica^ 

 Suffern, Mt. Kisco, Brewster, Newburg, Union ville, Washington- 

 ville, New Paltz and Walden. 



The correspondence of the mycologist has not been as large as it 

 should have been. It is earnestly requested that farmers report to 

 the Station any new plant disease or any unusual outbreak of the 

 common plant diseases which may come under their observation* 

 All queries will receive prompt and careful attention. 



The following subjects are discussed in this report : 



I, Two Destructive Lily Diseases; 



II. Prevention of Cabbage Club-Root ; 



III. Spraying Tomatoes ; 



IV. A Disease of Norway Maples ; 



V. Witches' Brooms on Cherry Trees ; 



YI. Observations on Exobasidium, Peckii and Ramidaria 

 cylindriopsis / 



VII, Inoculation Experiments with Gymnosporangiiim ma- 

 cropiis ; 



VIII. " Belted" Apples and Pears ;
