Assessment Status Notes

Justification

12,000 total number of mature individuals, with fewer than 1500 mature individuals per subpopulation.


Taxonomic notes

In early 2016 distinguished from the eastern species Neoalbatrellus caeruleoporus (Audet & Luther, 2016); existing records in databases such as Mycoportal.org are easily assigned to either species based on distribution.
The eastern species has been more often recorded than the western species.


Why suggested for a Global Red List Assessment?

This charismatic blue mushroom species is restricted in its distribution to the coastal areas of western North America from British Columbia into northern California, and fruits irregularly.


Geographic range

In coastal regions of British Columbia and Vancouver Island (Canada), the Cascades in Washington and Oregon, southwards along the coast into Sonoma County in California (USA). Restricted to the distribution area of Tsuga heterophylla.


Population and Trends

Known from scattered sites in British Columbia, Washington, Oregon and in coastal California (Audet & Luther, 2016; Castellano et al., 1999), up to a total of at most 30 sites (mycoportal.org). Despited being a Survey and Manage species (Castellano et al., 1999), not reported from suitable habitat in Oregon and Washington.

Population Trend:


Habitat and Ecology

Terrestrial, presumably forming ectomycorrhiza with Tsuga heterophylla, in various different stages of forest development, also with young trees. Fruiting repeatedly at the same location, but most often not in consecutive years. Often fruiting on non-natural disturbed soil surfaces, such as road banks.


Threats


Conservation Actions

Listed as a Strategy 1 Fungal species in the Northwest Forest Plan (Castellano et al., 1999) (as Albatrellus caeruleoporus), and being surveyed for since 1998.
