Some sort of Boletus but my fungal knowledge is limited.

Xerocomellus chrysenteron - Thanks ashgale it is exactly that though I understand can be confused with Boletus truncatus which are not found in the UK - they look the same to me but can only be told apart from the spores under microscope.

Ashgale's suggestion, "one of the Xerocomus chrysenteron group" may be as far as you can go as there are a good number of 'look alike' species to chrysenteron (some recently described). Macroscopically, flesh colour and colour changes to the flesh are very important in Xerocomus/Xerocomellus. Microscopically, cap cuticle structure and spores. Tree association is also important; and as it's under Beech it may indeed be chrysenteron! Porosporus has truncate spores; engelii has orange dots/patches in the flesh at the base of the stem; the flesh of pruinatus and cisalpinus tend to turn deep blue in part of the stem (may take 20 minutes); chrysenteron and bubalinus blue only slightly in the flesh. |

Thanks ruadh for information. Will have to look into it further. They are certainly doing well here, never seen so many all around all the beech trees and even along path and round the sheds, which get banked up with beech litter.
