Black spot at base

[jsanbor1]

Is this black spot at the base here anything to worry about? Any advice is appreciated.

I don't think it's a spot, I think your kenya tree is on the move. They will slowly crawl towards a spot they like.

I agree with the poster above I think it is the normal part of the foot.
