description Bjerkandera adusta Overview
Bjerkandera adusta, the smoky polypore, is a saprotrophic bracket fungus that grows on dead hardwood and is distributed across the Northern Hemisphere. Its thin, overlapping, shelf-like caps are pale to butterscotch on top, while the pore surface is smoky gray to black and may darken when bruised, handled, or dried. The dark pore layer contrasted with the paler flesh helps separate it from the similar Bjerkandera fumosa; it is a wood-decay fungus rather than an edible mushroom.
