Question
I think the brown object beneath the berries on what I think is a Juniperus virginiana tree is some sort of gall. The location: in an abandoned quarry (now a town park) in Rocky Hill, CT, 41.671736,-72.636182 .
Answer
Dear David, it looks as though you have photographed the cedar-apple rust gall, a species that is known to occur on species of Juniperus. Best wishes.
