Aureoboletus flaviporus, commonly known as the viscid bolete, is a species of bolete fungus found in western North America, where it grows in ectomycorrhizal association with coast live oak, madrone, manzanita,[2] and possibly with tanoak.

[3] In California, this mushroom appears during the rainy season in locations south of Mendocino County.

[3] This mushroom is "fairly common" but does not appear in large groupings, only as one-offs or small clusters in scattered locations.

[2] The cap is sticky-slimy, the pores are neon yellow, and this flesh of this bolete does not stain blue when it is cut or torn.

[2] The taste is said to be "acidic-lemony,"[3] and the overall edibility "mediocre"[2] because of a deficient combination of flavor and texture.
