Rank ReasonsAlbatrellus avellaneus occurs in coastal forests of northwestern North America (from northern California to southeastern Alaska), and east to at least the Cascade Range. There are estimated to be at least 50 locations, it may be under-reported, and the population appears to be stable. Threats include high intensity wildfire, development, road building and clearcut logging.
Range Extent CommentsAlbatrellus avellaneus is known western North America, along the Pacific coast from northern California, Oregon, Washington, British Columbia, to southeast Alaska. It mainly occurs in the Coastal Range, but some occurrences are known from the Cascades, and Blue Mountains in Oregon, and nearby western Idaho. The range extent is estimated to be 1,100,000 square kilometers. It has been reported disjunct in Oaxaca, Mexico but these and other disjunct occurrences need genetic confirmation (iNaturalist 2022, Loring 2019, MyCoPortal 2022, NatureServe 2022, Norvell 1995, Siegel 2021).
Occurrences CommentsThere are at least 50 occurrences (documented with observations or collections) of Albatrellus avellaneus (iNaturalist 2022, Loring 2019, MyCoPortal 2022, NatureServe 2022). It may be more common within the known range, it remains under-reported, partially due to the misapplication of the name Albatrellus ovinus to records which may actually be this species (Siegel 2021).
Threat Impact CommentsPrimary threats to populations of Albatrellus avellaneus include activities resulting in the loss of overstory, removal of host tree species, removal of litter and duff, and compaction or other soil disturbances. Natural and human-induced fires are also a threat, especially those with high heat intensity at ground level which result in tree mortality. Potentially threatening activities include logging (such as clearcutting or heavy thinning), certain kinds of fuels management, wildfire, and road, parking lot, campground, and trail construction. The above threats can each have negative effects on the fungal mycelium, the tree roots with which it associates, and sporocarp production. The loss of or damage to mycelium or associated root structures can result in extirpation or reduced population size, while reduction of sporocarp production can result in negative effects on reproduction and spore dispersal (Loring 2019).
