Assessment Notes

Taxonomic notes

Described as Ceriomyces mirabilis, then soon after transferred into Boletus (Murrill 1912). It has also been placed in the genera Boletellus and Xerocomus.

Based on phylogenetic data, this species was transferred into the genus Aureoboletus (Halling et al. 2015).

Synonyms: Ceriomyces mirabilis Murrill; Boletus mirabilis (Murrill) Murrill;  Boletellus mirabilis (Murr.) Singer; Heimioporus mirabilis (Murrill) E. Horak; Xerocomus mirabilis (Murr.) Singer


Why suggested for a Global Red List Assessment?

Aureoboletus mirabilis is a common bolete in western North America, roughly occurring in the range of its ectomycorrhizal partner, Tsuga heterophylla.
Population is widespread, and no decline has been observed. We recommend it should be listed as Least Concern (LC).


Geographic range

On the coast, it occurs from Sonoma County in northern California, USA, north into South-central Alaska. In the mountains, it occurs from the southern Cascade Range in Oregon, north into British Columbia, Canada, and east into the Rocky Mountains of Montana.


Population and Trends

Population is widespread, and shows no sign of decline.

Population Trend: Stable


Habitat and Ecology

Ectomycorrhizal with hemlock (Tsuga heterophylla and occasionally T. mertensiana) in young to mature forests in western North America. Typically fruiting from well decayed, moss-covered coarse woody debris.


Threats

None identified.


Conservation Actions

None needed.


Research needed
