Amauroderma rude

Amauroderma rude is a tough woody mushroom in the family Ganodermataceae. A polypore fungus, it is found in Eastern Australia, where it grows as a saprophyte on rotting, buried wood.

Etymology
Amauroderma means "dark/dusky-skinned" (from amauro, meaning "dark or dusky", and derma, meaning "skin"). The second half of the binomen, rude, means "robust".

Description
Fruit bodies have caps that are typically 4 – wide with alternating bands of light and dark brown rings. On the cap underside are small white to pale grey pores that initially turn red when bruised before turning black; this red-staining behaviour is unique in its genus. The light to dark brown stipe measures 5 – long by 1 – thick.
