Mycologia 



The leaves and smaller twigs and even the smooth bark of 

 larger branches are sometimes covered with sooty patches made 

 up of dense aggregates of the brown septate hyphae.

On the sycamore, definite, irregular, circular or angular spots, 

 dark-brown or purple, and 1-3 mm. in diameter are produced 

 on the upper surface of the living leaves. They frequently 

 show a brown center and the under surface of the spot is brown 

 throughout with a darker brown border. The spots frequently 

 become confluent and produce dirty-brown extended areas. The 

 spots may be very numerous and in nurseries much defoliation 

 results. 



On the walnut, this fungus produces subcircular spots I mm. 

 in diameter, dark-brown with a darker border on the upper 

 surface and uniformly brown on the under surface. The spots 

 may be few in number or they may be so numerous as to almost 

 completely cover the leaf. It is very severe in some cases and 

 causes much defoliation.
