There is a fungous disease of tlie l^orway maple wliicb miglit 

 be mistaken for leaf scorch by one unfamiliar with the latter 

 trouble. This is an anthracnose^, Gloeosporium apocryptum E. & 

 E., which attacks the leaves and young shoots. It is most severe 

 on small trees, especially nursery trees, occurring but rarely on 

 large shade trees. It attacks chiefly the terminal shoots, often 

 transforming them into much branched " heads." The leaves are 

 dwarfed and have a yellowish green color, with the margins curled 

 downward and blackened as if slightly frosted. This disease is 

 prevalent in Long Island nurseries and has been observed at 

 Geneva the present season on nursery trees and small shade trees.
