Assessment Notes

Taxonomic notes

First described as Dermocybe sierraensis (Ammirati, 1989), it was later transferred to Cortinarius (Niskanen, et al. 2013).


Why suggested for a Global Red List Assessment?

A small to medium-sized mushroom with an orange-brown to reddish-orange cap, bright to deep red gills, and rusty orange spores. It grows with Lodgepole Pine (Pinus contorta ssp. murrayana) in summer and fall.

Rare; only known from four locations in higher elevation Lodgepole Pine forests in the Sierra Nevada mountains, often near lakes, streams or other water sources.


Geographic range

Known from four sites in the southern and central Sierra Nevada in California, USA


Population and Trends

Currently known from four locations, two of which are historic. Populations are from high elevation Lodgepole Pine (Pinus contorta ssp. murrayana) forests near water sources.

Population Trend: Uncertain


Habitat and Ecology

Ectomycorrhizal. Fruitbodies scattered, growing from duff and soil under Lodgepole Pine (Pinus contorta ssp. murrayana). Only known from four locations in higher elevation Lodgepole Pine forests in the Sierra Nevada mountains, often near lakes, streams or other water sources. Fruiting in summer and early fall.


Threats

Too little is known regarding this species’ distribution and particular habitat preferences to properly assess possible threats. Mountain pine beetle outbreaks, leading to large scale dieback in Lodgepole Pine forest are likely detrimental to this species. Cortinarius sierraensis would likely be indiscriminately collected if found by dyers.


Conservation Actions


Research needed

Targeted surveys of suitable habitat to assess presences or absents of this species.


Use and Trade

Closely related species of Cortinarius are highly prized dye fungi. Cortinarius sierraensis would likely be collected if found by dyers.
