Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/198478685/198488235

Justification

Ramaria stuntzii is a locally common and widespread species in western North America, currently known from around 90 localities but believed to be under-reported; especially in California. No decline has been recorded, and it grows in multiple habitat types. It is listed as Least Concern.

Taxonomic notes

Ramaria stuntzii was described based on a Washington, USA, type collection (Marr and Stuntz 1973).

Geographic range

This species is found from the northern Californian, USA, coast, northward along the coast and Coast Range into southern British Columbia, Canada. It is uncommon through the Siskiyou Range, but is more common in the Cascade Range in Oregon into central Washington. It is rare in the northern Rocky Mountains in eastern Washing and Idaho.

Population and Trends

The population is widespread, and it can be locally common. Currently it is known from around 90 localities, with no recorded decline.

Population Trend: stable


Habitat and Ecology

It is ectomycorrhizal, occurring with both conifers and hardwoods. It is locally common from Mendocino County northwards in mature mixed hardwood/conifer coastal forests, and throughout coast, Coast Range and low- to mid-elevation Cascade Range forest in the Pacific Northwest. Like a number of Ramaria species in California, R. stuntzii appears to switch from being conifer associated in the northern part of its range, to tanoak associated (Notholithocarpus densiflorus) as it continues south.

Threats

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 forest-dependent fungi, and has been actively surveyed for since the late 1990s (Castellano et al. 1999). Research is needed to clarify the extent of this species' range and its habitat requirements.

Use and Trade

No use/trade is known.
