Tylopilus felleus, commonly known as the bitter bolete or bitter tylopilus, is a type of bolete characterized by slightly to distinctly pink pores on the underside of its bun-shaped brown cap, as well as a dark net on its thick stem. It is further distinguished by its intensely bitter taste. The mushroom forms mycorrhizal relationships with coniferous trees and can be found growing individually, sparsely, or in groups in coniferous woodland environments.

Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we recommend that you never eat wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.
