(1825) Fistulina hepatica, commonly known as the beefsteak fungus, beefsteak polypore, poor man’s steak, ox tongue, or tongue mushroom, is an unusual bracket fungus classified in the Agaricales.

The spores are pink[1] and released from minute pores on the creamy-white underside of the fruit body.

The underside (the hymenium) is a mass of tubules which represent a "reduced" form of the ancestral gills.

It is fairly common, and can often be found on oaks and sweet chestnut, from August to the end of autumn, on either living or dead wood.

It has a tendency to impart a reddish-brown stain to the living wood of oaks, creating a desirable timber type.

[6] It is edible and considered choice by some,[7] although older specimens should be soaked overnight, as their juice can cause gastric upset.
