Assessment Notes
Justification
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)
Taxonomic notes
Described based on a California, USA Type collection (Hesler & Smith 1979).
Why suggested for a Global Red List Assessment?
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)
Geographic range
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 and Trends
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: Stable
Habitat and Ecology
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.
Threats
No specific threats have been identified with regards to this species.
Conservation Actions
No specific conservation actions is needed with regards to this species.
Research needed
Genetic sequencing of southwest and Rocky Mountain collections, comparing them with California collections. More data to assess trends.
Use and Trade
None known.
