Subfloor help

I had some notable soft spots in a bedroom under my carpet. I pulled up the carpet and found 3/4" particle board with clear moisture damage. It disentigrated in my hands. Decided to pull it up and planned to replace with 3/4" plywood. As I pulled it, I noticed something growing on the 1x plank subfloor.

Here's a link to the photo:

I went ahead and removed the felt paper and spray down the subfloor with bleach solution. Question is do I need to do more before covering it back with felt paper and new plywood?

Any advice most welcome. My house is pier and beam.

It's hard to see the condition of the planks but there is a chance that the planks need to be replaced too. I don't see why the water damage would stop at the plywood.

Have we determined he source of the moisture damage? Is this on a crawl space or a 2nd story?

Is the subfloor still solid? Is there any mold visible between the planks? Is it feasible to remove one or two to look under them? Mold needs three things to grow; moisture, heat and a food source so if the moisture is removed, the mold can't grow.

btw - welcome to the forums Justin!
