Albatrellus subrubescens is a terrestrial polypore fungus. The fruit bodies of the fungus have whitish to pale buff-colored caps that can reach up to 14.5 cm (5.7 in) in diameter, and stems up to 7 cm (2.8 in) long and 2 cm (0.8 in) thick. On the underside of the caps are light yellow to pale greenish yellow tiny pores, the site of spore production. When the fruit bodies are fresh, the cap and pores stain yellow where exposed, handled, or bruised. The mushroom is found in North America, Europe and China, where it grows on the ground in deciduous or mixed woods, usually in association with pine trees. It is closely related, and physically similar, to the more common Albatrellus ovinus, from which it may be distinguished macroscopically by differences in bruising colors, and microscopically by the amyloid (staining bluish-black to black with Melzer's reagent) walls of the spores. The fruit bodies contain a chemical named scutigeral that has antibiotic and pharmacological activity. The fungus is inedible.
