Assessment Status Notes

Cannot be assessed as declining without motivation

Documentation need to be finalized under each heading.

Does seem to have a very wide ecology - LC but rare?

Justification

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


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

It is confined to the 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 and looked after during the last 20 years (Castellano et al., 1999), not reported from suitable habitat in Oregon and Washington.

ANDERS TO ELSE: It appears that the first and second sentence are in conflict with each other. State something about it rareness and if possible trends - is its habitat declining ?

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.

ANDERS TO ELSE: What is its typical habitat? it seems to have a wide ecology and just to be very rare. Perhaps rather assessed as LC and just very rare…or could it be so rare that there are less than 1500 mature individuals (150 genotypes) in W USA?

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

Temperate Forest

Threats

ANDERS TO ELSE: Information is missing


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.
