"Tylopilus felleus", formerly "Boletus felleus", is a fungus of the bolete family, found in Northern Europe and North America. It derives its specific name from the Latin "fel" meaning "gallbladder" referring to its bitter taste, like gallbladder. While it is not poisonous, it is not considered edible due to its bitterness.

Description

Up to 15 cm wide, the cap is grey yellow to pale brown, as is the stalk. Like most boletes it lacks a ring. It may be distinguished from "Boletus edulis" by its unusual pink pores.

Distribution and habitat

It grows in deciduous woodland, especially under beech and oak, on chalky ground from August to September, in Northern Europe and North America.

Taxonomy

A subspecies in the Great Lakes region, var. "uliginosus", was recognised by Smith and Thiers in 1971 [Smith AH & Thiers HD.(1971) The boletes of Michigan] .
