Bjerkandera adusta (Willd.) P.Karst. is a shelfed polypore mushroom that has a velvety, snow-white cap surface when young, becoming smooth and off-white as it ages. It is commonly called the “smoky polypore” because of the dark grey pore surface, though it also has distinct brown regions on the pore surface too. The spore print is white, containing tiny, hyaline, oval-shaped spores.
