The thinning leaves of autumn unveil and expose many of the trees in Wakulla County which have been concealed by their green cloak during the warmer months. Oaks, both deciduous and evergreen, may reveal a collection of knotty, hard tumor-like growths on twigs, branches and limbs.These rounded growths offer a stark contrast to the straight thin twigs and branches which shoot off at angles forming a porous maze for supporting leaves. The bulbous lumps may be few and scattered or come in heavy concentrations.

To the uninitiated these arboreal blisters may appear to be retained acorns. If in thick stands of trees, it can be difficult to tell which tree species is producing these galls.
