Help no longer needed;these plants have been ID'd

Ambrosia trifida a.k.a. Giant Ragweed
Fortunately, I'm not allergic to it.
Common ragweed, which is growing
in a nearby bed, has several ecological benefits.

One kind of Amaranthus a.k.a. Pigweed

Abutilon theophrasti a.k.a. Velvet Leaf or (East) Indian Mallow

One of the many Polygonum
(or sometimes Persicaria) species, a.k.a. Smartweed

And while you're here...
what about these mushrooms?
They're Boletus campestris.
