Leucopaxillus gentianeus

Leucopaxillus gentianeus is a bitter-tasting, inedible mushroom commonly known as the bitter false funnelcap, or the bitter brown leucopaxillus. A common synonym is "Leucopaxillus amarus". The bitter taste is caused by a triterpene called cucurbitacin B. The species was first described in 1873 as "Clitocybe gentianea" by French mycologist Lucien Quélet. František Kotlaba transferred it to "Leucopaxillus" in 1966.
The pileus ranges from wide and the stipe from long.
