Assessment Notes

Taxonomic notes

Described from a Type collection made in Idaho, USA (Miller 1966).


Why suggested for a Global Red List Assessment?

Chroogomphus pseudovinicolor is a locally common and widespread species in western North America, growing with Suillus pseudobrevipes in areas 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 locations 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 forests; especially in the Rocky Mountains, however trends to assess this species are lacking.

Population Trend: Uncertain


Habitat and Ecology

Chroogomphus pseudovinicolor has an obligatory relationship (likely as parasite) with Suillus pseudobrevipes, and possibly other Suillus species, which in turn are ectomycorrhizal with pines, especially Pinus ponderosa. Common in montane forests, fruiting in summer and fall.

Temperate Forest

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.

Use and Trade

This species is edible, but not often collected.
