Smoky polypore
Bjerkandera adustaAlso known as Smoky Bracket
Smoky polypore forms dense, overlapping tiers of thin brackets across fallen logs and weakened hardwood trees. Its most striking feature is the underside, where tiny pores turn distinctly smoky gray to dark blackish-ash while retaining a pale, contrasting margin. As a primary agent of white rot, it aggressively breaks down tough lignin and cellulose, recycling essential organic matter back into woodland soil.

Interaction riskLow

- Very high
- Why interaction risk is low
- Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Pore Inspection: Turn the shelf over to observe the characteristic charcoal-gray pore surface bordered by a clean white rim.
- Substrate Clues: Look for clusters on dead birch, beech, oak, or alder in damp, shaded forest hollows.
