Assessment Notes

Taxonomic notes

It was originally described as Polyporus flettii based on a collection made in Bremerton, Washington, USA (Morse, 1941), however, this name was invalid as it lacked a Latin description. It was transferred to Albatrellus and validated by Pouzar (1972). Audet (2010) erected the genus Albatrellopsis for this this, and closely related species.

Polypilus flettii (Morse ex Pouzar) Teixeira
Polyporus flettii Morse (invalidly published)

Why suggested for a Global Red List Assessment?

Albatrellus flettii is a easily recognized fungus of the Pacific Northwest and northern California. Ectomycorrhizal with conifers, it occurs in both coastal and montane forests. Although uncommon over much of it’s range, the widespread area of occurrence; with no decline noted, we recommend it be assessed as Least Concern (LC)

Geographic range

From Santa Cruz County, California, USA, north along the coast, inland in the Siskiyou mountains, in northern California, on the coast, Coast Range, and Cascade Range in Oregon and Washington, east to the northern Rocky Mountain in Idaho, and southern Alberta and British Columbia, continuing north along the coast into Southeast Alaska.

Distribution is scattered, uncommon in many areas, but can be locally common.

Population and Trends

Population appears to be stable, is widespread, and no decline has been noted.

Population Trend: Stable

Habitat and Ecology

Ectomycorrhizal with conifers, especially Sitka Spruce (Picea sitchensis) and Western Hemlock (Tsuga heterophylla), possibly with Chinquapin (Chrysolepis chrysophylla). Fruiting in late summer into winter. It appears in young to mature forests; no preferences have been noted.
