Assessment Notes

Taxonomic notes

Described by Zeller, (1941), from a collection made at Mount Shasta, in Siskiyou County, California, USA.


Why suggested for a Global Red List Assessment?

Currently known from 32 sites in western North America, including seventeen sites in California. Because of the dull colors, and growth habit (often buried in duff), this species may be under reported, and may end up being more common than currently thought. 

Recognized by the cushion-shaped fruitbody, with a tough whitish to gray peridium, and black powdery gleba with tough cords, often buried fruitbodies, and growth in high elevation forest. Microscopically, the large ovoid to irregular, smooth spores help set it apart from species that superficially resemble it.


Geographic range

Known from high elevation forest from the south-central Sierra Nevada of California, USA, north into the southern Cascade Range in wouthern Oregon the sky islands across the great basin, and the Rocky Mountains.


Population and Trends

Widespread across the western North American mountains, but rather rare. Occurring in drier, high elevation forest. However, little is known about what makes habitat suitable for this species. More data is needed for a proper assessment of trends.

Population Trend: Uncertain


Habitat and Ecology

Completely buried to partially exposed in duff under conifers in high elevation forest, especially under fir (Abies spp.) and pine (Pinus spp.). Fruiting in summer and early fall, fruitbodies may persist into late fall. Believed to be saprotrophic.


Threats

(All threats are hypothetical, as little is known about this species). Prolonged droughts and decades of fire suppression have drastically altered the high Sierra Nevada forests, leading to thicker, denser, Abies dominated forest. As a result, hotter, stand replacing fires (rather than patchwork and understory burns) are commonplace, altering appropriate habitat drastically, and making it ill-suited for this species.


Conservation Actions


Research needed

Targeted surveys for this species.
Identifying habitat suitable for this species.


Use and Trade

None known.
