hickory Phomopsis gall

Participants in the Diagnostic Walkabouts held as part of the Ohio Chapter ISA Field Day last Friday in Heritage Park, Westerville, OH, observed woody stem galls on hickory (Carya sp.). The galls were observed on the main stem and branches of two mature hickories growing just inside a forest next to a paved trail.

Spring marches forward at the Secrest Arboretum of the OSU Wooster Campus. Enjoy the river birches, the fungal and insect galls, and the marcescent beech leaves and watch for more developments soon as Growing Degree Day accumulate.
