Willow bracket

The upper surface grey on young fruitbodies, turning black and often developing vertical cracks when older, the outer margin remaining brown and velvety even on very old fruitbodies. Phellinus igniarius can grow up to 40 cm across and as much as 20 cm thick, the fruitbody is hoof-like and concentrically ridged in annual layers. The flesh inside these brackets is reddish brown. The tubes are brown, 3 to 5 mm deep and spaced at 4 to 6 per mm. They terminate in grey-brown to red-brown pores, sometimes having a purple tinge.
