Polyporus supinus

Polyporus supinus is a species of fungus in the family Polyporaceae. It is commonly known as the tilted polypore or supine polypore. This species is found in North America and Europe, where it grows on decaying hardwood logs and stumps.

Taxonomy

The species was first described scientifically by Elias Magnus Fries in 1821. The specific epithet supinus is Latin for "lying on the back" or "upward-facing", referring to the orientation of the fruit bodies.

Description

The fruit bodies of Polyporus supinus are annual and have a polypore morphology. The caps are fan- or kidney-shaped, measuring 2–10 cm (0.8–3.9 in) wide. The upper surface of the cap is white to cream-colored, and becomes yellowish with age. The pore surface is white, and the pores are small and round. The stipe is lateral or absent.

Habitat and distribution

Polyporus supinus is a saprophytic fungus, meaning it obtains its nutrients from dead or decaying organic matter. It is commonly found on decaying hardwood logs and stumps. The species has a widespread distribution in North America and Europe.

Edibility

While not generally considered a choice edible fungus, Polyporus supinus is reportedly edible when young and tender. However, due to its tough texture and lack of distinctive flavor, it is rarely collected for consumption.
