Treating wood for rot fungus

Question

I pulled the inside trim shroud from the bathroom skylight today.   It appears condensed pooled into the bottom and wicked into the paneling and ceiling bracing.  It's very minimal. The wood is not rotted but black mold has formed on the surface. It brushes away but I'm sure it would just come back once the bathroom gets moisture in it from use.  What should I use to treat this? I dont think get rot would be a good course of action because there is no physical damage, just the presence of fungus that if left untreated will become a problem. I'm thinking I just need to treat it so that the fungus is killed and then foam tape the shroud before I put it back up with new screws.

Git Rot might work but I am not sure about overhead wood work.

For mold/fungus I use something called Concrobium. It is sold in most hardware stores. An Industrial Hygienist told me about it when I had some mold in my shop at home.

Concrobium is a good chemical fungicide. Tea tree oil is a natural one. Most important is to clean it, get it dry, and seal the trim to keep moisture out. You might also consider brushing some urethane varnish on the wood and paneling to seal it.
