Assessment Notes
Taxonomic notes
Suillus pseudobrevipes was described from Idaho, USA (Smith & Thiers 1964).
Why suggested for a Global Red List Assessment?
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).
Geographic range
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 and Trends
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.
Population Trend:
Habitat and Ecology
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.
Threats
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.
Conservation Actions
No specific conservation actions have been identified with regards to this species.
Research needed
No specific research is needed with regards to this species.
Use and Trade
Suillus species are edible, but are not highly regarded, and thus only occasionally collected.
