Gyrodon lividus, commonly known as the alder bolete, is a pored mushroom bearing close affinity to the genus Paxillus.

The alder bolete was initially described by French mycologist Pierre Bulliard in 1791 as Boletus lividus,[2] before being given its current binomial name in 1888 by Pier Andrea Saccardo when he transferred it to Gyrodon.

[5] As a result of Singer's discovery, the genus Uliporus was rendered obsolete, and Boletus sistrotremoides became synonymous with Gyropus lividus.

[4] The generic term Gyrodon is derived from the Ancient Greek gyros "whorl" and odon "tooth",[6][7] while the specific epithet lividus is Latin for "lead-coloured".

[1] Gyrodon lividus has a pale brown, buff or ochre cap 4–10 cm (1.5–4 in) in diameter which is convex and later flat in shape, and can be sticky when wet.

[12] Gyrodon lividus is found across Europe, including Ķemeri National Park in Latvia,[13] In Asia, it has been recorded in China[14] and Japan.
