Comments: A. mellea is a very common species, edible when cooked, but is best eaten in small quantities because it has been reported to cause stomach problems. This species spreads by long black cords (rhizomorphs) in the soil and they can travel large distances to infect other trees. This is one of the most dangerous parasites of trees, causing diseases and ultimately death.
