Treating wood for rot fungus

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.

Thanks for the tips guys. I found the culprit. The sealant on the edge of the skylight had crumbed. I was able to pull it off by hand which exposed a nice hole in the skylight I could fit a pencil through. I ordered a new skylight off amazon to complete the repair.

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.

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.

Git Rot might work but I am not sure about overhead wood work.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?

Just make sure you've found ALL the fungus.
