Identify this bulb
My son and I were walking in the woods along a river bank and came upon these bulbs. I tried to dig it up thinking I could bring part of it home. I dug down over 6 inches and still didn't find the bottom of it. I didn't want to damage it, so I only took off 2 scales from the mother plant. The only thing we saw when we found it were 2 small cones sticking up out of the muck about 2 inches. The picture is of the 2 scales I took. The soil there was very black and wet. I have to go back out and bury the bulbs, but wanted a picture to identify. We live in southern Michigan. I'm still trying to figure out how to post the picture.
