Found under silver birch.
Cap grey 4-7 cm
The stem was blue but not just on handling. You can just see this on the one which has not been lifted. I only waited a couple of minutes after cutting it before photographing again, but you can just see colour beginning to develop in the stem and cap. Having read up since I got back I realise I should have left it a lot longer for the colour to develop.
I could find no mention of blue stem in my book, but otherwise I might have said it was a brown birch bolete. (Blue not as vivid on reduced quality photo).
Hope you can help.
Thanks,
Jane
