Bolete

'Bolete' is not one mushroom it is the name of a group of mushrooms with central stipes and pores under the cap instead of gills. With in the Bolete group there are many genera, each with many separate species. Your mushroom does appear to be a Bolete, but more information would be needed to know which. Clear pictures of the stem, pores & cross section (including details of any colour changes when cut) as well as information about the trees growing in close proximity are always useful when attempting to identify Boletes.

Gills or pores? :-)
