I think this is the same spider as the one in the dome web, taken about a foot below the web, but a month before. In my front yard in Baltimore.Baltimore West Quad
Life History/Behavior
The webs are found in trees, shrubs and tall weeds, and grasses in moist, wooded settings and can frequently be found along the banks of streams. The webs are oriented vertically and have a “signal” thread attached to the center that notifies the spider when prey has been captured. Unlike the Argiope garden spiders, Araneus marmoreus hides in a silken retreat to the side of the web (at the end of the signal thread). In adults, the retreat is made of leaves folded over and held together with silk. Immature spiders make their retreats out of silk only.
Egg cocoons, which contain several hundred eggs, are generally deposited in October and are constructed of white silk formed in a flattened sphere. Immature spiders emerge from the cocoons in spring. Adults are seen from midsummer until the first hard freeze of fall.
Medical Importance
As with the other orbweavers, the marbled orbweaver is not considered a medically important!

Orchard Orbweaver [Leucauge argyobapta]
ARACHNIDA > ARANEAE > Tetragnathidae
I've been watching the girl (an orb weaver of some kind) that shed this skin. She was eating well, as seen from the debris in her web, but after molting she abandoned her web, perhaps to head for buggier pastures.
This one isn't a quick match to my guides although it is quite distinctive. Will try to sort it out but may not be possible :)
This is the beautiful Orchard Orbweaver (Leucauge Venusta). Although it's name might suggest that it spends most of its time in orchards, apparently it likes the woodlands better. This time of year there are plenty of them available for the looking.

Female Spinybacked Orbweavers (Gasteracantha cancriformis) are one of the spider species with spines that stand out.
There’s a visible difference between the females and the males of the species. It’s the females that have the long abdominal projections commonly known as spines as males lack them or have very short spines.
6 red spines are seen on the dorsum of the female Spinybacked Orbweaver in Florida and the Southeast. Black spines are seen on the female Spinybacked Orbweaver in other states and areas of North America.
The main color of the spider is white. Additional black dots are seen along the body of the spider between the spines.
In rare cases, Spinybacked Orbweavers can also be yellow with either red or black spines.
