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