Bitter bolete
Tylopilus felleus
A species of Tylopilus.
Tylopilus felleus, commonly known as the bitter bolete, has a broad distribution spanning Asia, Europe, and North America. It typically thrives in shaded environments within diverse deciduous and coniferous woodlands. While its inherent bitterness makes it unsuitable for consumption, it poses no toxic threat—a fortunate fact for enthusiastic foragers who might confuse it with other, more palatable species.
