Distribution: Albatrellus avellaneus is a coastal species extending from California northward into Canada.
Habitat: Occur on soil, litter, or wood and is associated with western hemlock and Sitka spruce.
Conservation Status: Not of concern
There are about 10 species of Albatrellus in our region, including several rare or uncommon ones, and they occur on soil, litter, or wood. They are fleshy, but tough, and produce a single cap and stipe or multiple caps and stipes from a common base. It is medium-sized and several fruitbodies often occur together. The cap is white to yellowish or orange buff, sometimes with pinkish tones on the margin, but yellow and orange colors are more developed with age. The surface becomes fibrillose to scaly, with the scales sometimes slightly brownish. The tubes are decurrent and white to yellow- or orange-stained in age. The stipe is whitish above with brownish tones towards the base, and stains yellow to rusty orange in age. Dried specimens often develop orange and red colors. A. avellaneus is very similar to A. ovinus, which apparently does not occur in our region, and A. subrubescens, a species of montane pine forests that stains yellow to orange when bruised or in age. All of these fungi have white smooth spores; those of A. avellaneus and A. ovinus are non-amyloid while those of A. subrubescens are amyloid.
