Tylopilus felleus, commonly known as the bitter bolete or the bitter tylopilus, is a bolete that has slightly to distinctly pink pores on the underside of the bun-shaped brown cap and a dark net on the thick stem are characteristic of this bolete. It is also distinguished by a very bitter taste.

Cap Grey-yellow to pale- or walnut-brown, it is slightly downy at first and later becomes smooth with a matte lustre. It is initially convex before flattening out with maturity. Flesh whitish, with pinkish tinge beneath cap cuticle, unchanging, thick and firm. Stem pallid background with brown reticulation, stout and slightly bulbous. The mushroom has no ring.
