Polypore Fungus Pore Surface

A polypore fungus pore surface fills the frame, showing a dense field of round pores on the fungus's underside. The photograph is rendered in black-and-white with mid to high contrast; pale rims around each pore and darker interiors create a repeating textured pattern across a wide horizontal crop. At the right edge a fibrous margin marks where the pore field meets the fungus's outer body.
