I'm immensely impressed with Cybershot's speedy reply. I spent hours with keys and pictures and believe he may have come up with the answer within minutes of my posting the problem!. I looked carefully at both Boletes and the Earth/Puffball lot but could only get bits of each! We have many different Boletes here and the shape tallies too. Thanks very much for your help.

I did look also at the Pisolithus arhizus but it comes into the "inverted pear" shape which doesn't seem right in this instance. Neither does the colour but I daresay that varies.
