If you have the smallish, hard walnut looking propagating tubers, they will actually do better in the closet. They form as adaptation for a lily to survive the try season and will want to be either dried and stored or wet, heated and growing.
If you have the large remnant of the growing rhizome...I don't think there is much to be gained beyond stinking up your closet. They aren't designed to be stored.
I can get pictures tomorrow of what I am talking about, if that helps with the decision.
