About Aureoboletus flaviporus (Earle) Klofac
Aureoboletus flaviporus has a convex reddish-brown cap that is sticky-slimy, reaching up to 15 cm (6 inches) wide. Its pores are bright neon yellow, and its stem grows up to 15 cm long and 3 cm thick. The flesh of this mushroom does not turn blue when damaged, it has an acidic, lemony flavour, and it produces an olive-brown spore print. This species is native to western North America, where it forms ectomycorrhizal associations with coast live oak, madrone, manzanita, and potentially tanoak. In California, it fruits during the November to February rainy season, ranging as far north as Mendocino County. While it is a common species, it does not grow in large groups; it only occurs as solitary individuals or small scattered clusters. It is an edible mushroom, but its overall quality is considered mediocre due to its unfavourable flavour and texture.
