Assessment Notes
Justification
Suillellus amygdalinus is a common bolete in oak woodlands across western North America.
Population is widespread, and no decline has been observed. We recommend it should be listed as Least Concern (LC).
Taxonomic notes
Originally described as Boletus puniceus (Thiers 1965), however, this name was previous used for a species described from China (Chiu 1948); Thiers (1975) then changed the name to Boletus amygdalinus. Based on phylogenetic research, it was transferred into the genus Suillellus (Vizzini 2014).
Why suggested for a Global Red List Assessment?
Suillellus amygdalinus is a common bolete in oak woodlands across western North America.
Population is widespread, and no decline has been observed. We recommend it should be listed as Least Concern (LC).
Geographic range
Very common much of the oak zone in California, USA, south into Baja California, Mexico, with scattered populations north into the Columbia River valley in Washington.
Population and Trends
Population is widespread, occurring with oaks across the Pacific states. No decline has been noted.
Population Trend: Stable
Habitat and Ecology
Ectomycorrhizal with oaks (Quercus spp.), especially Coast Live Oak (Quercus agrifolia). Fruiting 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.
Research needed
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
None known.
