(Ranks from ORBIC, http://orbic.pdx.edu accessed January 24, 2014)
Type Locality: Humbolt, CA
Technical Description: Morphological habit Fleshy annual polypore,
single or many fruiting bodies. Pileus 40-100 mm broad, dry and dull,
circular to flabelliform, roughened to squamules forming, pale purple
brown, becoming pale orange to tan with dark squamules in age and may
exhibit pinkish to purplish tones. Pore surface initially white, staining
yellow, drying pale brown. Pore shape angular, 2-3 mm in diameter.
Stipe 60-180 x 10-15 mm, central, white with brownish tones near the
base, staining ochraceous and drying blackish brown. Context and tube
layer decurrent, white, staining yellow when cut, drying brown.
Basidiospores 4.8-6 x 3.4-4.5µm, broadly elliptical and profile ovoid,
thick-walled, smooth, hyaline, nonamyloid, spore print white. Taste none
to bitter Other Clamp connections absent. Hyphal structure monomitic.
Albatrellus avellaneus is very similar to A. ovinus and A. subrubescens.
They all have smooth spores, but A. subrubescens spores are amyloid. A.
avellaneus pileus is more orange buff in the center compared to A.ovinus
which is browner and has smaller spores.
Life History: This mycorrhizal species is slow to mature and fruits
infrequently. It fruits on the ground under conifers in October-January.
Range, Distribution and Abundance: Endemic to coastal lowlands in a
portion of the range of the northern spotted owl, from northern California
up to Canada. In Oregon and Washington, known from approximately
12 sites from the San Juan Islands and the Olympic Peninsula,
Washington and coastal Oregon. Other potential sites with vague locality
data extend the range to Humboldt Co., California.

FS/BLM lands in Oregon and Washington: Documented on the Olympic
and Siuslaw NFs, and Spokane BLM District.
Habitat Associations: Found under conifers, primarily associated with
large western hemlock/Douglas fir and spruce. Occurs principally in
coastal Sitka spruce, Western hemlock and in Pacific silver fir old growth
forest, at elevations of 112-1260 (472) feet of moist forest types. Most
collections are within 32 km of the pacific coast. Other associations have
also been found with Alnus rubra.
Threats: Removal of the hosts, Picea spp., and Tsuga spp., by heavy
logging, fire, road construction, or other management activities are the
most serious threats to Albatrellus avellaneus. Since most populations
are in areas of high recreational use, road, trail, and campground
construction could potentially impact these taxa.
Conservation Considerations: As a mycorrhizal species, Albatrellus
avellaneus forms symbiotic associations with the fine root systems of
plants, growing out into the soil matrix. Consider incorporation of patch
retention areas (as described in Standards and Guidelines 1994, C-41)
with occupied sites wherever possible.
