Biology
Leaf gall in madrone is caused by a fungus that infects leaf tissue. From late spring to mid-summer, fruiting bodies emerge from the leaf tissue, rupture the cuticle, and release their spores. Leaves become enlarged, discolored, and may exhibit a white, velvety appearance on one side. Spores in turn germinate on wet surfaces and may cause new infections of young, late-developing stems and leaves.
