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.

still shocked that the foam samples I sent it where not mold. clearly the drywall had mold so not shocked on the results there.

for reference, the sample report shows storage room. that’s a completely different room on the 2nd level than the pictures above show.

our old storage room has carpet from the 70-80s, and some water stains on a wall. figured I’d get it tested as well again, not shocked by results for storage room.
