If in doubt, get a few mold test kits from a realiable place. And if you’re really not sure, hire a person to do it.
Aside from the visible damage, you also need to check the nearby walls wood for dry rot damage.
Is this your rental or your primary..
If primary, it’s a nice time to replace with flooring you and your spouse like (other than carpet or wood)
