Leucopaxillus gentianeus is a bitter-tasting, inedible mushroom[2] commonly known as the bitter false funnelcap, or the bitter brown leucopaxillus. A common synonym is Leucopaxillus amarus. The species was first described in 1873 as Clitocybe gentianea by French mycologist Lucien Quélet. František Kotlaba transferred it to Leucopaxillus in 1966.[3]
The pileus ranges from 4–12 centimetres (1.6–4.7 in) wide and the stipe from 4–6 cm (1.6–2.4 in) long.[4] It has a mild to pungent smell and a bitter taste, rendering it inedible.[5] The bitter taste is caused by a triterpene called cucurbitacin B.[6] The spore print is white.[5]
The species can resemble L. tricolor and Russula compacta.[7]
