The mycelium or vegetative portion of the fungus shows in small, 

 irregular, fan-shajied areas of yellowish or buff color, when the sur- 

 face of diseased bark is shaved off or cut slantwise. This is the 

 portion which produces the spore-bearing pustules, and also the part 

 that saps the life of the bark. 



5. Death of tops of entire trees. These dead trees are often con- 

 spicuous because of the reddish-brown patches of bark, due to the pre- 

 sence of the pustules. In case the tree has been dead for a year or 

 more, the bark begins to peel off naturally in strips or shreds. 



6. Suckers or water sprouts, which develop at the base of the 

 cankers or at the base of the diseased tree. They are frequently 

 very numerous for one or two seasons, after which they are usually 

 killed by the fungus. 



If in doubt as to the existence of blight in your locality, communi- 

 cate with the Chestnut Tree Blight Commision, 1112 Morris Building, 

 Philadelphia, supplying all information of importance concerning 

 the matter.
