Mycologia 



It was stated in the September number of Mycologia that Dr. 

 C. T. Gregory had accepted a position in Norfolk, Virginia. Dr. 

 H. S. Jackson asks me to correct this erroneous statement and to 

 say that Dr. Gregory was retained after July i as extension 

 pathologist of the Indiana Agricultural Experiment Station, hav- 

 ing immediate charge of extension work in vegetable and truck 

 crop diseases. He did consider a position in Virginia, but finally 

 decided not to accept it. 



The American Journal of Botany for July, 1919, contains a 

 list of the publications of the late Prof. Atkinson prepared by Dr. 

 H. M. Fitzpatrick, of Cornell University. It covers five and a 

 half pages printed in small type. A brief sketch of his life ap- 

 pears in the same number. Another account appeared in the 

 Botanical Gazette, contributed by Prof. Whetzel, of Cornell. 

 The best recent photograph of Prof. Atkinson is probably the one 

 published by Mr. Lloyd in his Mycological Notes for June, 1919. 



Two valuable circulars were recently issued by Dr. Mel. T. 

 Cook, of the New Jersey Experiment Station. One deals with 

 the common diseases of herbaceous plants used as ornamentals, 

 and the other with the diseases of shade and ornamental trees. 

 They are both well illustrated, and contain directions for treat- 

 ment in all cases. The subject of ornamentals is too often over- 

 looked by the plant pathologist, who usually has more than he 

 can do in attending to the wants of diseased economic plants. 

 Here is a chance for the establishment of a fellowship for an ex- 

 tended investigation of the diseases of ornamental plants. 



In a report on white pine blister rust control for 1918, Dr. G. 

 P. Clinton and his associate, Dr. Florence McCormick, of the 

 Connecticut Agricultural Experiment Station, describe a method 

 of making artificial infections of detached leaves in Petri dishes, 

 where they may be kept alive for weeks and closely watched, 

 while the amount of moisture and light may be readily controlled. 

 Leaves of trees and shrubs may be handled in this way, but her- 

 baceous leaves are apt to wilt. In the same report, it is stated
