Fistulina hepatica Beefsteak Fungus
Found on living Sweet Chestnut but can occur on oak. This fresh pink annual poroid bracket is frequently described as tongue-like, varying in size from 50-200mm across. The upper surface is soft with minute bumps reminiscent of hair follicles. Changing hue with age to become rust-brown, tacky when damp, wide shallow furrows appear on both upper and lower surfaces.
