Peppery Bolete?

spicy to taste (yes I tasted a bit!). growing under birch. For me at the moment a similar species is Suillus bovinus - bovine bolete which lacks the peppery taste and I think is not so brightly coloured on the cross-section. http://www.first-nature.com/fungi/suillus-bovinus.php Suillus granulatus is potentially also similar but has a mild taste also. All three of these species are edible http://www.first-nature.com/fungi/suillus-granulatus.php According to Paul Sterry and Barry Hughes' 'Collins complete guide' C. piperatus is 'often found close to A. muscaria'. I have read online that once cooked C. piperatus loses it's spiciness and is edible. At least one site said C. piperatus isn't an edible species, the site may have even said it was poisonous. C. piperatus can be dried out and powdered and then used as pepper. One user on bushcraft.co.uk said he planned to dry and powder it and add it to dried and powdered Boletus Edulis and use as pepper.
