Assessment Notes

Taxonomic notes

Originally described as Helvella californica (Phillips 1880) from the Sierra Nevada in California, USA. Transferred into the genus Gyromitra (Raitviir 1965), then Pseudorhizina (Harmaja 1973).

Phylogenetic studies confirmed the placement in Gyromitra (Methven et al. 2013).


Why suggested for a Global Red List Assessment?

Gyromitra californica is a widespread species in the western North American mountains.

Although uncommon, the population occurs over a large area, and no decline has been reported. I recommend listing as Least Concern (LC).


Geographic range

Occurring in the Sierra Nevada mountains in California, north through the Cascade Range in Oregon and Washington, the Olympic Mountains in Washington, coastally north into Southeast Alaska, east into the Rocky Mountains, north into northern British Columbia, Canada.


Population and Trends

Population is widespread, occurring across the montane areas in the Pacific States. Population appears stable, with numerous recent observations.

Population Trend:


Habitat and Ecology

Often scattered or in small troops from humus or on rotting wood in wet areas (seeps, springs, creek edges, etc) in montane conifer forests. Fruiting from late spring into early fall.

Temperate Forest

Threats

No specific threats have been identified with regards to this species. Portions of the habitat are more susceptible to stand replacing forest fires, but if this is detrimental to the population in the long term remains unknown.

Increase in fire frequency/intensity

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

None known.
