Polyporus hydnoides

Polyporus hydnoides is a species of fungus in the family Polyporaceae. It is a type of basidiomycete fungus, which is a large division that includes forms like mushrooms, puffballs, and shelf fungi. The species is known for its distinctive hydnoid (tooth-like) structures on the underside of the fruiting body, which is a characteristic feature of this species.

Taxonomy

The species was first described scientifically by Elias Magnus Fries, a Swedish mycologist in the 19th century. The genus name Polyporus means "many pores", referring to the multiple pores present on the underside of the fruiting body where spores are released. The species name hydnoides refers to the tooth-like structures, a feature it shares with fungi in the genus Hydnum.

Description

The fruiting body of Polyporus hydnoides is a polypore, meaning it has a cap that is directly attached to the substrate without a stalk. The cap is typically brownish in color and can reach up to 10 cm in diameter. The underside of the cap features numerous small, tooth-like projections or spines, hence the name hydnoides. These spines are where the spores are produced and released.

Distribution and habitat

Polyporus hydnoides is found in various parts of the world, including North America and Europe. It typically grows on dead or decaying wood, particularly hardwoods. It is a saprophytic fungus, meaning it obtains its nutrients by decomposing organic matter.

Edibility

While not widely consumed, Polyporus hydnoides is considered edible. However, due to its tough texture, it is not highly regarded as a culinary mushroom. It is recommended to cook it thoroughly before consumption to break down the tough cell walls.
