Polyporus squamosus

Polyporus squamosus, also known as Dryad's Saddle and Pheasant's Back Mushroom, is a fungus that belongs to the Polyporaceae family. It is a common basidiomycete bracket fungus that is distributed widely in North America, Australia, Asia, and Europe.

Description

The fruiting body of Polyporus squamosus is large and distinctive, characterized by its flattened cap with scales or flaky patches. The color of the cap ranges from pale to dark brown and is often patterned. The stem is thick and short, often resulting in a lateral attachment to the host tree. The pores on the underside of the cap are small and round, and they produce a white spore print.

Habitat and Distribution

Polyporus squamosus is a saprophytic fungus, meaning it feeds on dead organic material. It is commonly found on dead hardwood trees, particularly elms and maples. It can also be found on living trees, where it causes a white rot. The fungus is known to be a perennial, producing a new fruiting body each year. It is widely distributed across North America, Europe, Asia, and Australia.

Edibility

While Polyporus squamosus is not generally considered a choice edible mushroom, it is not poisonous. The young fruiting bodies are the most palatable, as the flesh becomes tougher and more leathery with age. The taste is mild and the texture is similar to that of a watermelon rind.

Medicinal Use

There is some evidence to suggest that Polyporus squamosus has medicinal properties. It has been used in traditional Chinese medicine for its anti-inflammatory and anti-tumor properties. However, more research is needed to confirm these potential health benefits.
