Location obscured. On private property in Kansas City, KS. Very small, only a few mm long and there were many. I think this might be Cochlicopa lubrica? I am using A Pocket Guide to Kansas Land Snails by Dr. Joe Arruda.
Zoomed in on another photo of slime molds and found the snail
Found On a Dryads Saddle mushroom . It is alive
