and tomato canker has been discovered in several new localities — four 

 cases were reported from Kenilworth and one from Guernsey. 



In a more recent number of the Journal * several fungoid attacks 

 are reported ; Phyllosfkta prunicola was found on the leaves of Cox's 

 orange pippin. American gooseberry mildew has been doing serious 

 damage in districts where due care had not been taken to ward off the 

 attack ; several fungi have been found on tomato plants doing more or 

 less damage ; these were Fusarium Lycopersici and Cladosporium epi- 

 phyllum. From Long Niddry in East Lothian Sphserella tabifica was 

 reported on mangolds, and from Boston celery plants were sent that 

 were suffering from an attack by the fungus Sclerotinia sclerotiorum. 



E. Barsali f states that pine cones in the neighbourhood of Pisa did 

 not develop properly and became pale straw-coloured. There were 

 minute black points on the cone-scales that proved to be the pycnidia 

 of a Diplodia, but he scarcely considered these the cause of the mischief ; 

 it was rather due in part at least to the common mould, Tricothecium 

 roseum. Anything that impaired the vigour of the tree aided the growth 

 of the fungus. 



In a leaflet J published by the Board of Agriculture leaf -shedding 

 in Conifers is said to be caused by che attack of the fungus Botrytis 

 cinerea. The first indication of the disease is a yellowing of the leaves. 

 The affected shoots are twisted or curved downwards. Seedlings suffer 

 most. All diseased seedlings and leaves should be collected and burned. 



Another leaflet § deals with celery leafispot. It is caused by Phyl- 

 losticta Apii and was first detected in the United States. It appeared in 

 epidemic form in Sussex in 1909 in a field of celery, and much damage 

 was caused. Another celery-leaf disease is caused by Septoria Petroselhii. 

 It has long been known in this country and on the Continent. Spraying 

 with Bordeaux mixture is advised in both cases of disease. 



George Grant Hedgcock || has been searching for the cause of " pin- 

 rot " or " peckiness " in the incense cedar of California and Oregon, by 

 which great injury is done to the heart- wood of the tree. He ascribes 

 the disease to Polyporus amarus sp. n.
