Can you possibly identify what is going on with our tree.
There is a dark, almost powdery, layer between the bark and tree. And it has what I would describe as a moldy smell.
Only seeing it at the base.
Hoping there is a way to treat it instead of having to take it down.

Please have the tree evaluated by a certified arborist for further evaluation. Here is a link to help you find one in your area. https://www.treesaregood.org/findanarborist/arboristsearch
