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,[1] and possibly with tanoak.[2] In California, this mushroom appears during the rainy season in locations south of Mendocino County. This mushroom is "fairly common" but does not appear in large groupings, only as one-offs or small clusters in scattered locations.
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. The taste is said to be "acidic-lemony," and the overall edibility "mediocre" because of a deficient combination of flavor and texture. From 1905 until 2010, the binomial name of this fungus was Boletus flaviporus.[3]
