Demonstration of the inedible bolete: turns dark blue when flesh is exposed to air

Hi mate. Just a wee bit of info. That boletus you say is inedible because it turns blue is wrong. You can eat lots of the boletes that turn blue/black on cutting/ripping. The one your holding looks like a boletus erytrhopus which is yummy when cooked/fried in butter.

Thanks for the information! I think mushrooms are fascinating.
