Damp area on floorboards

Hello all,

I have recently pulled up some carpet and found a damp area on the floorboards in the passageway as can be seen in the pictures. I am not too sure what is causing it, but it is damp to touch.
The ceiling above is completely dry. I have cut a piece of the board and the underside of the timer is dry as well, with no water or dampness visible on the soil beneath. It looks as though the dampness is only in the top half of the timber as below the groove, it looks dry.
It is only in the one spot in the house, as all other rooms are fine. It has been there the last few months and doesn't seem to be drying.

Thank you in advance for any ideas on what it could be.

Welcome to the forums. It looks as if something oily was spilled there possibly prior to the carpet being laid. If it isn't drying, then it most likely is not water.

Ya, that's what I'm thinking as well - something oily rather than water. You might try scrubbing a portion of it with a rag wet with paint thinner and see if it cleans it up any.

Thanks for the responses,
I'm guessing its an oil stain of some sort, tried sanding it back which helped a bit on the edges, but it seems to be quite deep
