Summary:
Features include a cap that is whitish to yellowish or with orangish or pinkish or buff areas, a distinct stem, growth on the ground, inamyloid spores, and absent clamp connections. Colors overlap with Albatrellus ovinus and Albatrellus subrubescens and those species are reliably differentiated by their spores. The description is derived from Ginns(1) except where noted.

flesh and tubes stain yellow in KOH; FeS04 on cap bluish black and on flesh fuscous gray
