Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/198477782/198489840

Justification

Gomphidius smithii is a common species, especially in young Douglas Fir forests of the Pacific Northwest and northern California. No decline has been recorded nor threats identified, and it is listed as Least Concern (LC).

Taxonomic notes

It was described from Oregon, USA (Singer 1948).

Geographic range

It is widespread across the Pacific States of western North America, roughly following the coastal and northern Sierra Nevada distribution of Douglas Fir (Pseudotsuga menziesii var. menziesii) in California, USA, north through Oregon and Washington into southern British Columbia, Canada. It is known from a few scattered records the Rocky Mountains in eastern Washington, and from Arizona, and is likely to be more widespread through the Rocky Mountains, but not reported yet.

Population and Trends

The population is widespread, and it is a very common species especially in young Douglas Fir forests in the Pacific Northwest. No decline has been recorded, and subpopulations may have even increased with the the current forest management practices in the Pacific Northwest.

Population Trend: stable


Habitat and Ecology

Gomphidius smithii has an obligatory relationship (likely as a parasite) with Suillus lakei, and possibly other Suillus species, which in turn are ectomycorrhizal with Douglas Fir (Pseudotsuga menziesii). It is especially common in young to mid-seral stands of Douglas Fir in the Pacific Northwest and northern California, with fruiting in fall.

Threats

No specific threats have been identified with regards to this species.

Conservation Actions

No specific conservation actions have been identified with regards to this species, and no specific research is needed with regards to this species either.

Use and Trade

This and other Gomphidius species are edible, but are not highly regarded, and thus rarely collected for food.
