Assessment Notes
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.
