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, this species is assessed as Least Concern (LC).
was described from Idaho, USA (Smith and Thiers 1964).
This species is 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
The 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, but the overall impact on this species of this is unknown.
Population Trend: unknown
Habitat and Ecology
It is ectomycorrhizal with two- and three-needle pines; especially Ponderosa Pine (Pinus ponderosa
) and Lodgepole Pine (Pinus contorta
). It occurs 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 (Dendroctonus ponderosae
) outbreaks due to prolonged droughts and higher temperatures have killed millions of trees, in particular pines in the Rocky Mountains and the Sierra Nevada.
No specific conservation actions have been identified with regards to this species, and no specific research is needed either.
Use and Trade
species are edible, but are not highly regarded and thus only occasionally collected.
