Assessment Notes

Justification

Amanita aprica is a common and widespread species in western North America, with no recorded decline.

It should be listed as Least Concern (LC).


Taxonomic notes

Described based on a Washington, USA Type collection (Tulloss and Lindgren 1995).

There may be cryptic species under the name; more work is needed to delimit species concepts.


Why suggested for a Global Red List Assessment?

Amanita aprica is a common and widespread species in western North America.

It should be listed as Least Concern (LC).


Geographic range

Widespread in western North America, especially common in montane forests in the Sierra Nevada, Cascade Range, and northern Rocky Mountains. Occasional in other mountains ranges in the Pacific States and in coastal forests. 

Records on iNaturalist (2021) from eastern North America, and elsewhere are misidentified.


Population and Trends

Population is widespread, and locally, a very common species. Often fruiting in disturbed areas (old road edges, campgrounds, etc). No decline has been noted.

Population Trend: Stable


Habitat and Ecology

Ectomycorrhizal, most populations are with conifers; especially fir (Abies spp) and pine (Pinus spp.), but also with oaks (Quercus spp). Fruiting in spring across much of its range, occasionally winter in lower elevation sites and summer or early fall in high elevation populations.


Threats

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


Conservation Actions

No specific conservation actions is needed with regards to this species. Modern taxonomic work should be done on this group, and compare Coastal California oak associated collections with montane conifer populations.


Research needed

Modern taxonomic work should be done on this group, and compare Coastal California oak associated collections with montane conifer populations.


Use and Trade

None known.
