Population appears stable, and no declined has been recorded. It should be listed as Least Concern (LC).


Taxonomic notes

Described from Oregon, USA (Smith 1936).


Why suggested for a Global Red List Assessment?

Mycena tenax locally is a very common species on the Pacific Northwest of North American coast, and occasional in the Cascade Range. Also reported from Quebec, Canada, and likely more widespread than reports indicate.

Population appears stable, and no declined has been recorded. It should be listed as Least Concern (LC).


Geographic range

Southeast Alaska, USA, south through coastal British Columbia, Canada, more widespread in the Pacific Northwest, (from coast to Cascade Range) into coastal northern California, USA. Also reported from Quebec, Canada, and likely more widespread in northern conifer forests.


Population and Trends

Population is widespread, and locally it is a very common species. Called “by far the most common Mycena” in northern California spruce forests, “often carpeting the duff with thousands of fruitbodies” (Siegel & Schwarz 2016). No decline has been recorded.

Population Trend: Stable


Habitat and Ecology

Saprotrophic, growing on conifer needle duff and moss in young to mature forests. It has a preference for, but is not restricted to, wet spruce forests of Northern California and the Pacific Northwest.

Temperate Forest

Threats
