Assessment Notes

Justification

Aureoboletus flaviporus is a common bolete, 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).


Taxonomic notes

Described as Boletus flaviporus (Earle 1905), where it remained until it was transferred to the genus Aureoboletus (Klofac 2010).


Why suggested for a Global Red List Assessment?

Aureoboletus flaviporus is a common bolete, 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).


Geographic range

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 and Trends

Population is widespread, and shows no sign of decline.

Population Trend: Stable


Habitat and Ecology

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.

Temperate Forest

Threats

Loss of habitat due to urban sprawl, drought stress in southern California, and stand replacing fires. But probably not at a scale to affect the overall population.
