Bitter boletes are common throughout the summer. They can still be found into the fall but are often reduced to a pile of sludge with autumn rain.

It is ok to taste and spit a small amount of this mushroom. You will notice an immediate blue bruising when damaging the tissue and the bitter taste will be apparent after 5 seconds of chewing. I’d recommend spitting before you taste the bitterness because it can sneak up on you.
