The deformity that you show in the photo is called "fasciation".


Fasciation can be caused by a genetic mutation, bacterial or mite infestation or systemic herbicide damage.

You can prune those pieces out and if you have not begun a dormant spray program then start ASAP. Horticultural oil and copper fungicide spraying is organic program compatible and will help to suppress over-wintering insect and mite pests, fungal and bacterial infections.
