ARTIST CONK,
Ganoderma applanatum
Ganoderma applanatum is an important decay of dead trees but may enter living trees through wounds and cause extensive damage. The fruiting bodies are perennial, leathery to woody and tend to be flat or plate-like. The upper surface is light brown, deeply zoned, and often covered with a dusting of brown spores. The lower surface is white turning brown in old specimens or when bruised or marked, hence the common names "picture fungus" or "artist's conk."
