Assessment Notes
Justification
Lactarius aestivus is a common species in northern California and the Pacific Northwest in fir and hemlock forest.
Population is widespread and stable, no decline has been recorded; it should be listed as Least Concern (LC).
Taxonomic notes
Described from a Type collection made in Washington, USA (Nuytinck & Ammirati 2014).
Older records were called by the European name Lactarius deliciosus; 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 underscibed species in western North America.
Why suggested for a Global Red List Assessment?
Lactarius aestivus is a common species in northern California and the Pacific Northwest in fir and hemlock forest.
Population is widespread and stable; it should be listed as Least Concern (LC).
Geographic range
Occurring 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 & Ammirati 2014), geographical parameters are lacking data; this species likely occurs north into British Columbia, and possibly into southeast 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
Ectomycorrhizal with fir (Abies spp.) and hemlock (Tsuga spp.). Common in late summer and fall in the Pacific Northwest, and fall into winter in California; growing in young to mature forests across northern California and the Pacific Northwest.
Threats
