Bay Bolete

I believe these are Bay Boletus though I suppose they could be Slippery Jack. However, they are under oak rather than pine and the ochre yellow tubes turn blue when pressed. Had to cut short the morning walk (so no time to revisit the magpie inkcaps) when the spaniel started limping. He cut his foot on something so I had to take him to the vet. We may be restricted in our wanderings for a week or so.
