Assessment Notes

Taxonomic notes

Ramaria rubrievanescens was described based on a Washington, USA Type collection (Marr & Stuntz 1973).

Although the name has been applies to eastern North American and European collections, we are not aware of genetic studies comparing these collections with western North American counterparts, and at this time, are not included in the assessment.

Why suggested for a Global Red List Assessment?

Ramaria rubrievanescens is a common widespread species in western North America. No decline has been recorded, and it can be locally abundant in your to mature forests. Therefore I recommend listing as Least Concern.

Geographic range

From the north coast, Coast Range, and Sierra Nevada of California, USA, north through the Pacific Northwest into southern British Columbia, Canada, east into the northern Rocky Mountains.

Population and Trends

Population is widespread, and likely highly under reported. During the 2011-2013 US Forest Service surveys in the Mount Shasta area of the southern Cascade Range in California, it was collected 35 times, from over 20 distinct populations; and locally was one of the more abundant marco fungus fruiting.

Population Trend: Stable

Habitat and Ecology

Ectomycorrhizal, associated with conifers, especially fir (Abies spp.). Common in mid-seral stage to mature, mid- to high-elevation forest, occasional in lower elevations. Fruiting in summer and fall.

Temperate Forest


No specific threats have been identified with regards to this species.

Conservation Actions

This species is included on the United States Forest Service Northwest Forest Plan Survey and Manage list of rare/old growth forests dependent fungi, and has been actively surveyed for since the late 1990’s. (Castellano et al. 1999).

Research needed

No specific research is needed with regards to this species.

Use and Trade

This species is edible, but rarely collected for food.
