White fungus on my mature maple tee
I have noticed a white frisbee sized growth on the Trunk of my large maple tree. Is it bad for The tree?
Clackamas County Oregon
Thank you for your question about your maple tree. There’s a very good chance that the white spot is not a problem. It’s quite likely it is lichen. Lichens are common on woody plants, especially older, or slow-growing, specimens.
We should be able to identify the spot with several well-focused images. Please send an image of the tree, overall, another one or two of the spot. You can attach up to 3 pictures when you respond to this email. If you prefer, you can send additional images with a 2nd reply.
I look forward to seeing your images so that we can set your mind at ease.
