Where do stinkhorn mushrooms grow?

Like all fungus, stinkhorns can also sprout out of the wood of dead and decaying trees. Varieties of stinkhorn fungus grow naturally throughout nearly all of North America and into Central America. Some varieties prefer subtropical and tropical regions, including parts of Mexico.

Stinkhorn mushrooms grow on rotting organic matter. Remove underground stumps, dead roots, and sawdust left from grinding stumps. The fungus also grows on decomposing hardwood mulch, so replace old hardwood mulch with pine needles, straw, or chopped leaves.
