I can see now that this is Black Bryony. I was wary of my identification, because I had an earlier photo of Woody Nightshade, and they looked different, but I wrongly decided that it was the earlier photo I'd misidentified.
Obvious differences are that this plant has clear parallel veins in its leaves, and Woody Nightshade would hold the base of each fruit with a 5-pointed star shaped calyx.
I put my own offering on about a week ago so i had been looking at Black Bryony.
