No, that is staghorn sumac. Poison sumac has white berries that are borne on fruiting structures at the leaf axil (where the compound leaf meets the stem).
Thank you Nate. So poison sumac has multiple fruiting structures where the leaf branches come out of the stem. Leaf structure is the same? What about size of the plants? Ive always liked Sumac as it looks so exotic adjacent to what I learned at MSU to be a michigan beach maple succession. Can you upload a photo better illustrate the distinctions? Many Thanksshows the distinctionss
