MOLD, or is it.

yes 9x9 tiles. already assumed they are asbestos tiles.

Probably going to do some self leveling concrete to encapsulate them. or put vinyl flooring down to cover the up.

I did end up buying a mold test to sample the green specs, and a few other things around the house.

If you think it is I would treat it that way. Better safe than sorry IMO.
