I have a thing for railroad trestles. Here's another one, but this one is actually a tunnel on a footpath beneath the right of way, and the stonework is just gorgeous. I simply had to share it. It's a treasure, built just like the old Roman Legions would have done it. Janesville, Wisconsin (USA).
Pretty sure these are oyster mushrooms. I didn't pick 'em though. Found on a downed log, floating in what's left of the flood waters, Janesville, Wisconsin (USA).
