PLATE VI. 
Leaf-scab of Lemon (various Fungi). 
Fig. 
1. Upper surface of Lemon leaf (nat. size). 
2. Under surface of same leaf. 
The leaf on both surfaces was largely covered with “scab,” and 
towards the tip where there was no scab withering and decay 
had set in. No less than six fungi were found upon this single 
leaf, together with the remains of a remarkablo Scarlet Mite, 
which probably was the primary cause of disease. 
3. Under surface of Orange leaf, showing numerous brown pustular 
bodies, due to the excessive development of corky tissue.
