Renovating the bathroom and found these dark patches in the joists and roof lumber surrounding the old vent pipe. The PVC part is new.

Anything bad here? Anything we need to address?

    It looks in the image like there might be some fungus. To me that’s a sign that it’s worthwhile to get someone professional to at least give it a look in person.
