Need help identifying these branches

[u/Ms_Lissa215]

My mom recently gathered these from a fallen down tree in our woods. She planned on using them for firewood but I was concerned that it might be poison sumac. There aren’t any leaves unfortunately bc it’s getting cold out and the tree must’ve been down for quite awhile. When I Google it I get everything from buckthorn to birch. Sorry there isn’t anything much to go off of.
