I cut several of these off my Euonymous in my front yard. "Newer" growths appear light, while older growths are dark brown. I attached some examples, including the largest one I have found. Is it a gall?
Washington County Oregon galls
Thank you for your question. Yes; it appears to be a crown gall, which you can read about here: https://hgic.clemson.edu/factsheet/euonymus-diseases-insect-pests/ Hope this is helpful.
