Wild Fistulina hepatica (Beefsteak Fungus)

This image features Fistulina hepatica, commonly known as the beefsteak fungus, ox tongue, or beefsteak polypore. It is a striking bracket fungus found primarily in Britain, Europe, North America, and Australia.

The beefsteak fungus typically grows on deciduous hardwoods, notably oak and occasionally sweet chestnut, often causing a rich brown coloration in the heartwood known as 'brown oak'. Because it is a naturally occurring wild mushroom and not a commercial manufactured product, it has no corporate owner, manufacturing facility, or commercial brand affiliation.
