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. It is currently known from around 100 collections from at least 50 localities, and believed to be under-reported. No decline has been recorded, and so it is assessed as Least Concern.

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).

Geographic range

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

Population and Trends

The population is widespread across the Cascade and Coast Range in the Pacific Northwest and northern California. It is currently known from ~100 collections from 50+ locations, and considered to be more common than the number of collection records indicates. For instance, limited macrofungi surveys in the vicinity of Mount Shasta in the southern Cascades in the fall of 2011 and 2012 found eight new sites. There are also a number of recent collections from Oregon, suggesting this species is stable.

Population Trend: stable

Habitat and Ecology

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


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 1990's (Castellano et al. 1999). No specific research is needed with regards to this species.

Use and Trade

No use/trade is known.
