Honey fungus grows on dead plant life, most often on rotting trees. While it generally does not pose any type of risk, it has been known to grow on living plants and kill them. If you find honey fungus on your property, kill it immediately to prevent the risk of it spreading to healthy plants. Before you take the time to kill the fungus, you should make sure it actually is honey fungus.
Examine the growth pattern. Honey fungus grows in clusters, often with 10 or more mushrooms per cluster.
Examine the color of the mushrooms. Honey fungus has very light brown stems with creamy, light brown or honey-colored caps.
Look for a scaly ring that wraps around the stem of the mushrooms. While this isn't always present in young fungus, it will be there on older fungus. The rings should be on mushrooms that are 2 inches or taller.
Examine the gills beneath the cap. Honey fungus gills have a solid white color.
Pull a cluster of the fungus out of the ground. Honey fungus has dark brown to black rhizomorphs beneath the clusters. These rhizomorphs look similar to roots of a small plant.
Break open the stem of a mushroom. The center of the stem should look pithy and spongy.
