There needs to be air for this to grow, replace the corks or bottles.
Sometimes the mold that they make the bottle in will have a ridge
inside too, you can see it on clear bottles. If the cork does not
expand fully and make intimate contact with the bottle this can
happen. Don't worry about cleaning necks when inserting, the cork
will do that on it's way in. If you replace corks swab out the area
where the mold was growing with sulfite.
