Fungi or black mold in wood flooring

Q: We had our apt floor put in 4 years ago when we renovated. A few months later small black spots started appearing and have grown in number. They are mostly circular and dark black and mostly around the dining room table, but not all right under it. I don’t believe they are from anything we spilled. Near the sink and front door (where there’s much more traffic, moisture, etc.) there are no spots.

We have no pets (unless children count). I read a post somewhere that said these black mold in wood flooring (?) spots are mysteries and the best explanation might be fungus that was in the trees themselves. Any advice?

A: I think I would agree with the idea of a fungus from the tree and just by bad luck happened to be in the few pieces you see. Best bet is probably simply to replace the affected pieces.
