Assessment Notes
Justification
Lactarius aestivus is a common species in northern California and the Pacific Northwest in fir and hemlock forest. The population is widespread and stable and no threats have been reported. It is listed as Least Concern (LC).
Taxonomic notes
It was described from a type collection made in Washington, USA (Nuytinck and Ammirati 2014). Older records were called by the name
Lactarius deliciosus, a European species; which was applied to a complex of species in North America. It is a member of
Lactarius sect.
Deliciosi; which still has a number of undescribed species in western North America.
Geographic range
This species occurs in western North America, from the northern California Coast and northern Sierra Nevada, north through the Cascade Range, and widespread in coastal and montane forests throughout the Pacific Northwest. Being a recently described species (Nuytinck and Ammirati 2014) data on its range limits are lacking. This species likely occurs north into British Columbia, and possibly into south-east Alaska, and east into the Rocky Mountains.
Population and Trends
Lactarius aestivus is a common species with a widespread population; occurring in young to mature hemlock (Tsuga spp.) and fir (Abies spp.) forests. No decline has been observed.
Population Trend: stable
Habitat and Ecology
It is ectomycorrhizal with fir (
Abies spp.) and hemlock (
Tsuga spp.). It is common in late summer and fall in the Pacific Northwest, and fall into winter in California. It grows in young to mature forests across northern California and the Pacific Northwest.
Threats
No threats have been identified with regards to this species.
Conservation Actions
No specific conservation actions are needed with regards to this species. Further data is needed regarding the range of this species.
Use and Trade
This species is edible, and occasionally collected for food.
