I store a little swivel desk stool underneath my ping-pong table in the basement and I noticed one day that the cloth on the chair looked like it had round water stains. I then folded the table sides up and witnessed a constellation of dust on the underside (on both sides).

I took several paper towels and cleaned it off. After cleaning, a faint imprint remains. It kind of has the consistency of spider webs. The dust invariably grows back in a few weeks.
I am simply curious as to what this is, because I've never seen dust in clusters like this (as opposed to a thin, uniform layer). I hope it is not mold or fungus. The room is relatively clean and I can't find this dust anywhere else in the room or under other tables. Why the ping-pong table?

I would check for sources of water leakage or excessive humidity in the room it appears to be some sort of mold and based on what you told me about what led to its appearance it sounds even more like some kind of mold.
