Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/198479755/198487124

Justification

Mycena quiniaultensis is an uncommon Mycena. It is currently known from around 100 collections from at least 50 localities, and appears to have a preference for mature and old growth forests but is not limited to these habitats. Based on the fact it is a general litter decomposer, and considering the widespread distribution and number of collections, it is assessed as Least Concern (LC).

Taxonomic notes

This species was described from Lake Quinault on the Olympic Peninsula of Washington, USA (Smith 1935).

Geographic range

This species is known from coastal forests from Vancouver Island, British Columbia, Canada south to Santa Cruz, County, California, USA, and in the Cascade Range in Washington and Oregon, and the Siskiyou Range in southern Oregon and northern California.

Population and Trends

This species is currently known from around 100 collections from 50 or more localities, and is likely under-reported. It still should be considered an uncommon mushroom and it appears to have a preference for mature and old-growth forests, but is not limited to these habitats. Data to fully asses trends are lacking. There are a number of recent observations on iNaturalist (2021), and with these recent observations, knowledge about the range and habitat affinities of this species has greatly expanded.

Population Trend: stable


Habitat and Ecology

It is saprotrophic on needle duff, debris and moss under conifers; especially Redwood (Sequoia sempervirens) in California, and wet conifer forests in the Pacific Northwest. It appears to have a preference for, but is not limited to, mature and old-growth forests.

Threats

Continued loss of mature and old-growth forests, due to logging and stand replacing fires, is likely to impact 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). Management is needed to cease logging of old-growth forests and limit clear-cutting practices. A better understanding of this species' distribution and habitat requirements is also required.

Use and Trade

No use/trade is known.
