Aureoboletus flaviporus
Aureoboletus flaviporus, commonly known as the viscid bolete, is a species of bolete fungus. From 1905 until 2010, its binomial name was Boletus flaviporus.
Description
The reddish-brown cap is convex, sticky-slimy, and up to wide. The pores are neon yellow. The stem is up to 15 cm long and 3 cm thick. The flesh does not stain blue when damaged. It has an acidic and lemony flavour. The spore print is olive-brown.
Similar species
Aureoboletus auriporus is the most similar species in the genus. A. viridiflavus is similar as well.
The species is found in western North America, where it grows in ectomycorrhizal association with coast live oak, madrone, manzanita, and possibly with tanoak. In California, this mushroom appears during the rainy season as far north as Mendocino County. The species is common but does not appear in large groupings, only as one-offs or small clusters in scattered locations.
Uses
The quality of the edible mushroom has been described as mediocre because of poor flavor and texture.
