Assessment Notes

Taxonomic notes

Leucogaster citrinus was described from California, USA (Harkness 1899) as Leucophleps citrina, and later transferred into the genus Leucogaster (Zeller and Dodge 1924).


Why suggested for a Global Red List Assessment?

Leucogaster citrinus is a common and widespread hypogeous fungus in the Cascade and Coast Range in the Pacific Northwest, and northern California, east into the northern Rocky Mountains.

Currently known from ~100 collections from 50+ locations, and believed to be under reported. No decline has been recorded.

I recommend listing as Least Concern.


Geographic range

From southern British Columbia, Canada, south through the Coast Range and Cascade Range into northern California, USA, east into the northern Rocky Mountains. There is also a historic record from the San Francisco Bay Area.


Population and Trends

Population is widespread across the Cascade and Coast Range in the Pacific Northwest and northern California. Currently known from ~100 collections from 50+ locations, and considered to be more common than the number of collection records indicates. Limited macro fungi surveys done in the vicinity of Mount Shasta in the southern Cascades in the fall of 2011 and 2012 found eight new locations. There are also a number of recent collections from Oregon, suggesting this species is stable.

Population Trend: Stable


Habitat and Ecology

Ectomycorrhizal, found in association with Pinaceae, especially firs (Abies spp.) in young to mature forests. Fruiting in fall. This species is dependent on mycophagy (primarily eaten by small mammals) for spore dispersal.   

Temperate Forest

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 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

None known.
