Assessment Notes
Taxonomic notes
Described as Gomphidius tomentosus, from a Washington, USA Type collection (Murrill 1912), later transferred into the genus Chroogomphus (Miller 1964) where is resides today.
Why suggested for a Global Red List Assessment?
Chroogomphus tomentosus is a common species in hemlock forests of northern California, the Pacific Northwest, into south-central Alaska. No decline has been recorded; it should be listed as Least Concern (LC).
Geographic range
Widespread in western North America; on the coast, it occurs from Sonoma County in northern California, USA, north into South-central Alaska. In the mountains, it occurs from the southern Cascade Range in Oregon, north into British Columbia, Canada, with scattered records east into the northern Rocky Mountains.
Population and Trends
Population is widespread, and it is a very common species. No decline has been recorded.
Population Trend: Stable
Habitat and Ecology
Chroogomphus tomentosus has an obligatory relationship (likely as parasite) with Aureoboletus mirabilis, which in turn is ectomycorrhizal with hemlock (Tsuga spp.). It is especially common in the Pacific Northwest into southeast Alaska, fruiting in late summer and fall.
Threats
No specific threats have been identified with regards to this species.
Conservation Actions
No specific conservation actions have been identified with regards to this species.
Research needed
No specific research is needed with regards to this species.
Use and Trade
Chroogomphus tomentosus is edible, but only occasionally collected for food.
