is a common species on the Pacific Coast of North America, from northern California into Alaska, with occasional reports from the Cascade Range in the Pacific Northwest. It is likely that it is under-reported, and so may be more common and occur more widely within the known range than presently recognized. The population appears to be stable and no threats have been identified. It is assessed as Least Concern (LC).
Described by Pouzar (1972), from a collection made in Humboldt Co, California, USA. The name Albatrellus ovinus
, a European and eastern North American (and possibly Rocky Mountain) species, has been misapplied to A. 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. Its distribution continues north into south-central Alaska, USA. It also occurs in the Cascade Range with Engelmann Spruce (Picea engelmannii
), but is much more localized in this habitat. Reports from Mexico probably represent a different species, and Rocky Mountain specimens should be compared genetically with Pacific Coast specimens, to confirm/refute conspecificity. It remains under-reported, partially due to the misapplication of the name Albatrellus ovinus
to records likely to represent this species.
Population and Trends
The population appears to be stable 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 areas subject to small-scale disturbance.
Population Trend: stable
Habitat and Ecology
It is ectomycorrhizal, associated with spruce (Picea
spp.), most common in coastal habitats, often in younger forests. Fruiting occurs in fall, with long-lasting fruitbodies.
No specific threats have been identified with regards to this species.
No specific conservation actions are needed with regards to this species. Rocky Mountain collections should be compared genetically with Pacific States collections. The identity of Mexican 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.
