Assessment Notes

Taxonomic notes

Described based on collections from Washington and Oregon, USA (Bas 1969).


Why suggested for a Global Red List Assessment?

Amanita smithiana is a common and widespread species in western North America.
Population appears stable, and occurs over a wide range, and no decline has been noted. I recommend it should be listed as Least Concern (LC).


Geographic range

Pacific Northwest of North America, from southern British Columbia, Canada, south from coast to Cascade Range, through the Sierra Nevada, California, and coastally into Santa Cruz, County, California, USA. Also expected in the northern Rocky Mountains. Reported from single collection from Idaho, New Mexico and Mexico (Tulloss 2021); these collections should scrutinized more.


Population and Trends

Population is widespread, and locally common in the Pacific Northwest and northern California. No decline has been noted.

Population Trend: Stable


Habitat and Ecology

Ectomycorrhizal with conifers, especially Douglas-fir (Pseudotsuga menziesii), and possibly with Tanoak (Notholithocarpus densiflorus) in California. Fruiting in fall.

Temperate Forest

Threats

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


Conservation Actions

Research needed

Genetically compare Rocky Mountain collections with ones from the Pacific States.

Taxonomy

Use and Trade

None known. This species is toxic.
