Amanita novinupta is a common and widespread species with oaks in western North America. No decline has been reported nor any threats identified. It is assessed as Least Concern (LC).

Taxonomic notes

Amanita novinupta was described from western North America (Tulloss and Lindgren 1994); before that it was recorded under the European species A. rubescens (Thiers 1982, Arora 1986). There are cryptic species in the A. novinupta complex; one of which, A. cruentilemurum Tulloss nom. prov. (Tulloss et al. 2021) can now be differentiated, but some of the records of A. novinupta likely pertain to this, and possibly other species.

Geographic range

This species is widespread in western North America; very common in coastal California from San Diego into Mendocino County; scattered in the California mountains, and occasional records through the Pacific Northwest into southern British Columbia, Canada. Also it is expected to occur in northern Baja California, Mexico, but subopulations from Arizona and New Mexico are suspect; they likely represent Amanita cruentilemurum Tulloss nom. prov.

Population and Trends

The population is widespread, and locally it is a very common species occurring in young to mature forests, especially with oaks (Quercus spp.). No decline has been noted.

Population Trend: stable

Habitat and Ecology

It is ectomycorrhizal with oaks (Quercus spp.), and possibly with conifers. It occurs in young to mature forests, especially with Coast Live Oak (Quercus agrifolia) in central and southern California.


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

Conservation Actions

No specific conservation actions are needed with regards to this species. Modern taxonomic research is needed to delimit species concepts in the Amanita novinupta complex.

Use and Trade

This species is edible, but not often collected.
