Described as Boletus flaviporus (Earle 1905), where it remained until it was transferred to the genus Aureoboletus (Klofac 2010).
Aureoboletus flaviporus is a common bolete, commonly occurring in California, USA, with its preferred ectomycorrhizal partner, Coast Live Oak. Also occasionally with other oak species around the Central Valley in California, and north into Oregon.
Population is widespread, and no decline has been observed. We recommend it should be listed as Least Concern (LC).
Common from the San Francisco Bay Area in California, USA, south to Baja California, Mexico. Scattered populations do occur north into Oregon, USA. Mostly in coast and coast range forests, occasionally in the oak zone on the east side of the Central Valley of California.
Population is widespread, and shows no sign of decline.
Population Trend: Stable
Ectomycorrhizal with oaks (Quercus spp.), especially Coast Live Oak (Quercus agrifolia). Typically in stands of oak with thick duff, or duff buildup, without a grassy or weedy under story. Fruiting from fall into spring.
Loss of habitat due to urban sprawl, and stand replacing fires. But probably not at a scale to affect the overall population.
This species is edible, and occasionally collected for food.
