Assessment Notes
Taxonomic notes
Suillus fuscotomentosus was described from California, USA (Smith & Thiers 1964).
Why suggested for a Global Red List Assessment?
Suillus fuscotomentosus is a common Suillus with three-needle pines in California, occurring in both coastal and Sierra Nevada forests. No decline has been noted, and population is widespread. Therefore I recommend listing as Least Concern (LC).
Geographic range
California, USA; on the Central Coast north through the San Francisco Bay Area, into the Coast Range, and throughout the Sierra Nevada foothills and mountains into the southern Cascade Range in Oregon, USA.
Population and Trends
Population is widespread and appears stable overall. Portions are under threat (ie. coastal Pinus radiata forests), but not at a scale large enough to affect overall populations.
Population Trend: Stable
Habitat and Ecology
Ectomycorrhizal with three-needle pines; especially Monterey Pine (Pinus radiata) and Knobcone Pine (P. attenuata) in coastal populations, and Ponderosa Pine (P. ponderosa) in Sierra Nevada populations; but apparently not with Jeffrey Pine (P. jeffreyi) in the eastern Sierra Nevada. Fruiting in fall and winter, and can be locally abundant.
Threats
Native stands of Pinus radiata are under threat from development, and a change in fire regime. Pinus ponderosus has suffered die-back from drought stress in the Sierra Nevada foothills. However, these threats are likely at a scale that has little affect on the overall population.
Conservation Actions
No specific conservation actions is needed with regards to this species.
Research needed
No specific research is needed with regards to this species.
Use and Trade
This species is edible, but rarely collected for food.
