Suillus lakei, commonly known as the matte Jack, Lake's bolete, or the western painted Suillus, is a species of fungus in the Suillaceae family. It is characterized by the distinctive reddish-brown tufted fibers or small scales on the cap, and the presence of a woolly veil on the stem. The caps can reach diameters of up to 15 cm (5.9 in), while the stems are between 6 to 12 cm (2.4 to 4.7 in) long and usually 1–3 cm (0.4–1.2 in) thick.

It is native to northwestern North America, but has been introduced to Europe, South America, and
