Leaf gall is an unsightly condition in azalea shrubs caused by the fungus exobasidium vaccinii. However in most cases the condition will always turn brown. The fungus also makes crazy looking growths appear on flowers and foliage alike. The disease starts out with a few leaves getting thick and waxy and usually a bright green in color.

Exobasidium vaccinii otherwise known as azalea leaf and flower gall causes azalea leaves to look thick fleshy and curled. If you have weird looking growths on your azaleas those unusual bumps are called azalea leaf galls which are eruptions in the plant tissue. It is a fungus that infects the growth of your azalea causing damage to leaves flowers buds or stems. Over time they turn whitish with disease spores accumulating.

Unlike many galls that appear on woody plants and trees leaf gall on azaleas is caused by the fungus exobasidium vaccinii a wind borne fungus that can overwinter on bark and within buds. This fungus infects young spring growth and causes the leaves flowers buds or stems to become distorted and misshapen with fleshy bladder like growths. Azalea leaf gall is a disease that usually looks worse than it actually is. I am given to understand that early pioneers would pickle the galls with spices and vinegar and enjoy them as a delicacy.
