Possible causes
Roof leaks, plumbing, exterior intrusion, bathroom humidity, condensation on cooler surfaces, or earlier water damage can all create damp conditions.
Why paint is not a moisture repair
Coating over active growth or damp material does not remove the cause. The area should be cleaned or removed as appropriate and fully dried before finishes are restored.
Surface growth versus concealed damage
A small isolated surface area can be different from growth that extends into drywall, insulation, or a cavity. Recurrence and water staining are clues that a deeper evaluation may be worthwhile.
