Appearance
- Bracket
- A very large, hard, and woody perennial growth that is typically hoof-shaped or cushion-like. The surface is concentrically ridged or grooved, starting out finely velvety and rusty brown before turning gray and finally black. As it ages, the surface becomes smooth but deeply cracked or crazed, and it often supports the growth of moss and algae.
- Pores
- Small and circular, numbering about 4 to 6 per millimeter. The color ranges from rusty cinnamon and maroon to reddish-brown or gray-brown as they weather.
- Tubes
- Arranged in layers, typically 2 to 5 millimeters deep per year; colored cinnamon to reddish-brown, sometimes becoming filled with white mycelium in older sections.
- Flesh
- Dense, brittle, and very hard; reddish-brown in color. The taste is reported as sour or bitter, and the smell is described as fungus-like.
- Spore print
- White.
