There is a special beauty in the form and structure of a bare tree after it has dropped its annual crop of leaves. Like the beauty of a classical statue, one can see the truth of its bones. Leaves, for all of their movement and color, veil the beauty of branches and buds. Looking at a bare tree is a study in pure potential.

But that wasn’t the case 400 years ago, before European colonists began exploring for interesting tree species, transplanting them to new areas, and exporting them back to Europe. The original native range of Magnolia grandiflora is only from the Carolinas south to Florida and westwards towards Texas along the Gulf Coast.

If the growth on your tree bark is shaped like a shelf and looks like a mushroom, it is a conk. Conks indicate that the tree has internal decay.
