Figure 3. Identified and labeled by Kevin Herman.

• First appears as dark spots on the top side of the leaf.

• The spots then turn a dark brown and the underside of the leaf is symmetric with a lighter-brown spot.

• The leaf begins to yellow around the spots.

• Some spots dry up and fall off the leaf giving it a "shot-hole" appearance.

• Eventually the leaf will turn completely yellow and fall off the tree.
