There are many varieties of porcelain-berry (Ampelopsis brevipedunculata) in the Pittsburgh area. Most have maple-shaped leaves (below), but I occasionally find the intricate leaves showcased above.
No matter the variety, you can identify them in October by their porcelain-like berries.
Unfortunately, Ampelopsis is invasive. When you see Pittsburgh hillsides engulfed like this, it’s probably porcelain-berry. This hill is along Pocusset in Schenley Park.

Aww Kate you are always so informative. I have often wondered what that Grape-like vine was called. We joked and called it Kudzu altho I know it doesn’t grow this far north. Thanks for sharing your knowledge. I guess we are never too old to learn !
I have noticed two things porcelain-berry. One, it usually stems back down to one main rooted stalk so if you can find the main stem you can cut it and kill the trailing vines above easily. Two, the rooted portions are ruthlessly able to regenerate, but if you keep on top of them or dig them out really well you can at least keep it in check if it turns up in your yard.
