This is one of my favorite daytime shots I took using the macro setting. How large is this mushroom? About an inch to an inch and a half wide. There were many signs of growing mushrooms in the heavily moisture of the Boundary Waters Canoe Area. There has been quite a bit of rain in the midwest as many of you are aware of. I was surprised when I returned from my week in the BWCA to find so much rain and flooding in many of the midwestern states.
