Assessment Notes

Taxonomic notes

Described from Oregon, USA (Kauffman 1924).


Why suggested for a Global Red List Assessment?

Gomphidius subroseus is a very 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 western North America, roughly following the coastal and Sierra Nevada distribution of Douglas-fir (Pseudotsuga menziesii var. menziesii) in California, USA, north through Oregon and Washington into southern British Columbia, Canada. It also occurs in the Rocky Mountains in southern British Columbia and Alberta, Canada, south through Idaho and Montana, and scattered through the mountains in Colorado, Utah, New Mexico and Arizona with Rocky Mountain Douglas-fir (Pseudotsuga menziesii var. glauca). Distribution records in the Rocky Mountains are sparse in comparison to Pacific State collections.


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 subroseus 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
