Nice so definitely is Lamiaceae, just not the Lamium genus.
Reminds me of White Dead-Nettle (Lamium album) but the leaves are slightly different.
Just to clear up: "Although its external appearance is generally that of a long-nosed mouse, a shrew is not a rodent, as mice are, and is in fact more closely related to moles. Shrews have sharp, spike-like teeth, not the familiar gnawing front incisor teeth of rodents." http://en.wikipedia.org/wiki/Shrew
Katydid. Not sure more specifically.
Polypore mushroom is my best guess. Could be turkey tail/Trametes.
Don't touch! Nasty, nasty sting. Other name is "cow killer."
