Mushroom-shaped mushrooms usually last 2 weeks or less before rotting away. These black warts can persist for multiple years. These are the fruiting bodies of Hypoxylon fragiforme, a fungus that feeds almost exclusively on the wood of beech trees. Also called, ahem, "beech balls," these fruiting bodies start reddish but turn black over time.
