The Birch Bracket, scientifically known as *Piptoporus betulinus*, is a common bracket fungus found almost exclusively on birch trees. It plays a crucial role in the decomposition of dead or weakened birch wood. The fungus is characterized by its kidney-shaped to semicircular fruiting body, which is typically white to light brown in color. The surface is smooth and dry, and the flesh is soft and spongy when young, becoming tougher with age. It lacks a stem and attaches directly to the tree. While it is not considered poisonous, its tough texture makes it unpalatable for most people, though it has been used traditionally for medicinal purposes.
