Antrodia serialis

Antrodia serialis is a species of polypore fungus in the genus "Antrodia". Originally named "Polyporus serialis" by Elias Fries in 1821, it was given its current name by Marinus Anton Donk in 1966. A widespread species, "A. serialis" causes heart rot in living trees. In North America, it is often confused with the morphologically similar "Antrodia serialiformis", which grows on oak.
