This species was described from northern California (Nuytinck et al. 2006).
Some collections appear to have been called Lactarius deliciosus var. olivaceosordidus (Hesler & Smith 1979, Methven 1997).
Lactarius aurantiosordidus is a small, dingy colored member of the Lactarius ‘deliciosus’ group, growing with Sitka Spruce on the Pacific Coast from northern California into Alaska.
Not enough data exist to assess trends, or total population. Until such time data exist, I suggest listing as Data Deficient (DD).
Known from coastal forests from northern California into southeast Alaska, roughly following the distribution of Sitka Spruce (Picea sitchensis) (iNaturalist 2021, N. Siegel unpublished data).
Population is widespread; but being a recently described, and hard to identify species, date to assess trends is currently lacking.
Population Trend: Uncertain
Ectomycorrhizal with Sitka Spruce (Picea sitchensis) in coastal forests. Fruiting in summer in the north, into late fall in the south.
Climate change is affecting Sitka Spruce forests on the southern portion of its range; but probably not at a scale to affect the population overall.
Widespread logging in British Columbia, Canada and southeast Alaska, USA.
Protect mature and old growth spruce forests in British Columbia and Alaska.
Data to assess trends, and population data across the range of this species.
This species is edible, but appears to be rarely collected.
