Scytinostroma galactinum

Scytinostroma galactinum is a species of fungus in the family Stereaceae. It is commonly known as the Milk-white Toothed Polypore due to its distinctive white color and tooth-like structures on the underside of its fruiting body.

Taxonomy

The species was first described scientifically by mycologist Miles Joseph Berkeley in 1851. The genus name Scytinostroma is derived from the Greek words skytinos (hard) and stroma (a bed), referring to the hard, crust-like nature of the fruiting bodies of species in this genus. The species name galactinum is derived from the Greek word galaktos (milk), referring to the milk-white color of the fruiting bodies.

Description

The fruiting bodies of Scytinostroma galactinum are polypores, meaning they have a porous underside rather than gills. These pores are actually tiny tubes where the spores are produced. The fruiting bodies are typically hard and crust-like, with a white to cream color. The surface is often wrinkled or furrowed, and the edges may be slightly rolled under.

Distribution and habitat

Scytinostroma galactinum is found in various parts of the world, including North America, Europe, and Asia. It grows on dead or dying hardwood trees, particularly oak and beech. It is a saprophytic fungus, meaning it obtains its nutrients by decomposing dead organic material.

Edibility

While not considered poisonous, Scytinostroma galactinum is not generally regarded as edible due to its tough, woody texture. It is, however, used in some traditional medicines in Asia.
