Neofavolus alveolaris

About

Neofavolus alveolaris, commonly known as the hexagonal-pored polypore, is a species of fungus in the family Polyporaceae. It causes a white rot of dead hardwoods. Found on sticks and decaying logs, its distinguishing features are its yellowish to orange scaly cap, and the hexagonal or diamond-shaped pores. It is found in Eurasia and Australia; once thought to be widely distributed in North America, these specimens may belong to Neofavolus americanus.
