Question
Hello. A lot of Poison Ivy plants in my area are infested with this strange growth. By Google imaging a description, I found another example, but the author didn't know what it was. I live in the Amesbury-Newburyport area.
Answer
chaffeemonell, this is a gall on the Toxicodendron plant. I do not know the insect that has created it. Most of the galls that are found on this genus appears more as small red bumps on the blade surfaces, rather than a congested area of unusual growth. This might require an entomologist to answer. Best wishes.
