Assessment Notes

Justification

Cantharellus formosus is a very common chanterelle in the Pacific Northwest of North America.

Being a highly prized edible species, it is sought after by many mushroom hunters and foragers. It is commercially harvested across much of it’s range. No decline has been observed due to harvesting, and populations are likely more widespread and common due to forest management practices for increased timber production.

This species should be listed as Least Concern (LC)


Taxonomic notes

Cantharellus formosus was described from Vancouver Island, British Columbia, Canada (Corner 1966), however this name was rarely used, and the complex of western North American golden chanterelles were generally recorded as C. cibarius until the pacific golden chanterelle harvest paper (Redhead et al. 1997).

Geographic range

From northern California on the coast, inland in south-central Oregon throughout the Pacific Northwest from lowlands to through the Cascade Range, north into British Columbia, and coastally into Southeast Alaska.


Population and Trends

Population is widespread across much of the Pacific Northwest of North America, and northern California coast. With the current forestry practices and logging regimes, and this species preference for younger forests, it has probably become much more common in the past few generations. Widespread collecting has not affected populations.

Population Trend: Improving


Habitat and Ecology

Ectomycorrhizal with conifers; especially common in young to mid-seral stage Douglas-fir (Pseudotsuga menziesii) and Western Hemlock (Tsuga heterophylla) forests in the Pacific Northwest. Also abundant in coastal forests dominated by Sitka Spruce (Picea sitchensis). Typically starting fruiting in late summer, and continuing into 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. Genetic studies on Cantharellus in the Pacific Northwest, to assess variation of collections being called C. formosus.
