Assessment Notes

Taxonomic notes

Described by Pouzar (1972), from a collection made in Humboldt Co, California, USA.

Albatrellus ovinus, a European and eastern North American (and possibly Rocky Mountain) species, has been a misapplied name for A. avellaneus.

Why suggested for a Global Red List Assessment?

Albatrellus avellaneus is a common species on the Pacific Coast of North America, from Northern California into Alaska, and occasional in the Cascade Range in the Pacific Northwest. It remains under reported, partially due to the misapplication of the name Albatrellus ovinus. No decline has been noted, and the population appears to be stable. Based on this, we recommend it be assessed as Least Concern (LC)

Geographic range

Albatrellus avellaneus is common on the North Coast of California and coastal Oregon in suitable habitat; coastal Sitka spruce (Picea sitchensis)-Western hemlock (Tsuga heterophylla) forests, continuing north into south-central Alaska, USA. It also occurs in the Cascade Range with Engelmann Spruce (Picea engelmannii), but much more localized in this habitat. Rocky Mountain species should be compared genetically with Pacific Coast specimens. Reports from Mexico probably represent a different species.

It remains under reported, partially due to the mis-application of the name Albatrellus ovinus.

Population and Trends

Population appears to be stables, over a widespread area (from northern California, USA, through coastal British Columbia, Canada, north into Alaska, USA), east to at least the Cascade Range.

No sign of decline has been observed, and it seems to have a preference for younger forest; often around small scale disturbance.

Population Trend:

Habitat and Ecology

Ectomycorrhizal, associated with spruce (Picea sp), most common in coastal habitats, often in younger forests. Fruiting in fall, with long lasting fruitbodies.


No specific threats have been identified with regards to this species.

Conservation Actions

No specific conservation actions is needed with regards to this species.

Research needed

Rocky Mountain collections should be compared genetically with Pacific States collections.

Mexico collections labeled as Albatrellus avellaneus should also be investigated.


Use and Trade

This is an edible species, but rarely collected for food. This trend may change as more people are foraging for mushrooms in the Pacific Northwest.
