Described based on a California Type collection (Hesler & Smith 1979).
Lactarius subvillosus is an uncommon to locally common species in northern California and Oregon, USA.
Little data is available to assess trends, and southwest collections should be compared genetically with California collections before an assessment is made. Therefore I recommend listing it as Data Deficient (DD)
From Santa Cruz County, California, USA, in coast and Coast Range forest north into northern Oregon, and scattered locations in the Sierra Nevada foothills of California. Also reported from Arizona, New Mexico and Colorado, however collections from these areas should be compared genetically to California collections.
Population is widespread, but this species is uncommon over much of the range, locally common in Mendocino and Humboldt County, California. Population appears stable, but limited data is available to asses trends.
Population Trend:
Ectomycorrhizal, occurring in mixed evergreen forests on Northern California and conifer forests in Oregon. Likely associated with Douglas-fir (Pseudotsuga menziesii), fruiting in fall and winter.
No specific threats have been identified with regards to this species.
No specific conservation actions is needed with regards to this species.
Genetic sequencing of southwest and Rocky Mountain collections, comparing them with California collections. More data to assess trends.
None known.
