Suillus pseudobrevipes was described from Idaho, USA (Smith & Thiers 1964).
Suillus pseudobrevipes is a common and widespread species in western North America with two- and three-needle pines.
Although some decline in pine forest has occurred, it does not appear to be at a scale to be detrimental to this species. Therefore I recommend listing as Least Concern (LC).
Very widespread in the mountains of western North America; (Cascade Range, Sierra Nevada and Rocky Mountains) and scattered on the coast of California and Oregon.
Population is widespread, occurring over a very large area with young to mature two- and three-needle pines. Mountain pine beetle outbreaks have led to a decline in pine; especially in the Rocky Mountains.
Ectomycorrhizal with two- and three-needle pines; especially Ponderosa Pine (Pinus ponderosa) and Lodgepole Pine (Pinus contorta). Occurring in both coastal and montane forests, in young to mature forests.
Prolonged droughts and decades of fire suppression have drastically altered western montane forests, leading to thicker, denser, Abies dominated forests. As a result, hotter, stand replacing fires (rather than patchwork and understory burns) are commonplace, altering appropriate habitat drastically, and making it ill-suited for this species. Pine beetle outbreaks due to prolonged droughts and higher temperatures have killed millions trees, in particular pines in the Rocky Mountains and the Sierra Nevada.
No specific conservation actions have been identified with regards to this species.
No specific research is needed with regards to this species.
Suillus species are edible, but are not highly regarded, and thus only occasionally collected.
