Bracket Fungus (Conk) on Tree Trunk: What It Means

A conk (bracket fungus) at the tree base indicates internal decay. The fungus entered through an old wound (mower damage, etc.) and has been decomposing sapwood. The visible shelf is the fruiting body—the infection is advanced.

Consult a certified arborist (Georgia Arborist Association) for a health assessment. Structural failure risk is real.
