I don't think there are any causes from the outside wall as the level
of the floor is raised about 5 feet above the ground. There is only a
10' wide cemeted sidewalk gangway between our building and the next one
over. I will try cleaning out the mold with water and bleach and am
considering painting the wall when I'm done with Kilz.

Is the adjacent wall connected to a bathroom? If not, it sounds like you're
on the right track and you might just want to better ventilate the closet to
reduce humidity.
