been found that if the dirt is dug away until the graft unions are 

 exposed and cylinders of heavy roofing paper placed around the 

 base of the trees and the soil filled in, that the fungus is prevented 

 from entering the walnut trunk. 



The species of Russula found in the State of North Carolina 

 have been treated by H. C. Beardslee in the Journal of the Elisha 

 Mitchell Scientific Society for January, 1918. Many of the notes 

 and photographs are by Dr. W. C. Coker. The style of treat- 

 ment is the same as that of other papers on fleshy fungi appear- 

 ing in this journal. Forty-seven species are recognized, among 

 % which the following are described as new: R. cincrascens, R. 

 magna, and R. pungens. 



A disease of narcissus which has been attributed to a species 

 of Fusarium, a microscopic fungus, is now known to be due to a 

 nematode. The disease appears first in the neck of the bulbs, 

 causing the leaves at and below the soil to decay and fall over. 

 The nematode may pass from the diseased parent bulb to an off- 

 set but does not appear to pass from one bulb, to another in storage. 

 Rotation, trap-plants, heat, and spraying solutions are mentioned 

 as preventative and remedial measures. 



Bulletin 658 of the United States Department of Agriculture, 

 by James R. Weir and E. E. Hubert, gives an outline of forest 

 disease surveys, which are carried out in conjunction with timber 

 survey projects in order to obtain data of economic value in 

 conducting future sales of the areas in question. The results are 

 recorded on pathological maps, indicating the principal infection 

 areas. Several of the common fungous diseases affecting trees 

 are described and illustrated in this bulletin. 



Specimens of Globifomes grave olens were recently collected by 

 Professor A. H. Graves on a living red oak trunk near New Dorp. 

 Staten Island. This very curious and interesting tree-destroying 

 fungus was first described from Georgia by Schweinitz and is of
