Fistulina hepatica 

Fistulina hepatica01301

FISTULINA hepatica grows on hardwoods, especially oak and chestnut. The  bracket “Beefsteak Fungus” or “Ox Tongue” looks like a piece of liver and even bleeds a red liquid when cut. It is both parasitic and saprotrophic. Tubes are not attached to each other. Annual. Cooking removes the tannic acid it acquires when growing on oaks.
