How do you know that the mushroom is a bitter bolete?

Answer 1

To identify a bitter bolete, look for its distinct characteristics: it typically has a cap that ranges from brown to reddish-brown, a thick stem, and a spongy underside with pores instead of gills. When sliced, the flesh may exhibit a blue or green discoloration. Most importantly, tasting a small piece will confirm its bitterness, as bitter boletes are known for their unpleasant taste, which can help differentiate them from edible varieties. Always exercise caution and consult a reliable field guide or expert, as some mushrooms can be toxic.
