Assessment Notes

Taxonomic notes

Described from Oregon, USA (Singer 1948).


Why suggested for a Global Red List Assessment?

Gomphidius smithii is a common species, especially in young Douglas-fir forests of the Pacific Northwest and northern California. No decline has been recorded; it should be listed as Least Concern (LC).


Geographic range

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.
Known from a few scattered records the Rocky Mountains in eastern Washington, and from Arizona. Likely more widespread through the Rocky Mountains, but not reported.


Population and Trends

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 populations 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 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, fruiting in fall.

Temperate Forest
