Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/198480944/198489208

Justification

Suillellus amygdalinus is a common bolete in oak woodlands across western North America. The species is widespread, and no decline has been observed. It is listed as Least Concern (LC).

Taxonomic notes

This species was originally described as Boletus puniceus (Thiers 1965), however, this name was previously used for a species described from China (Chiu 1948). Thiers (1975) consequently changed the name to Boletus amygdalinus. Based on phylogenetic research, it was transferred into the genus Suillellus (Vizzini 2014).

Geographic range

This species is very common in much of the oak zone in California, USA, south into Baja California, Mexico, with scattered subpopulations north into the Columbia River valley in Washington.

Population and Trends

The population is widespread, occurring with oaks across the Pacific states of USA, as well as in Baja California, Mexico. No decline has been noted.

Population Trend: stable


Habitat and Ecology

It is ectomycorrhizal with oaks (Quercus spp.), especially Coast Live Oak (Quercus agrifolia). Fruiting occurs from fall into spring.

Threats

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

Conservation Actions

No specific conservation actions are needed with regards to this species. There are at least two undescribed Suillellus species occurring in western North America in the process of being described. Delimiting these species from existing records of Suillellus amygdalinus will be needed.

Use and Trade

No use/trade is known.
