Northwest Ohio has been receiving a fair amount of rain in the last month or so. This has led to some beautiful mushroom blooms.
Cathy Wilson is my friend and mushroom advisor. She helped me identify this as an Omphalotus species, which are fluorescent. I didn't get a chance to see this for myself, but I'll give it a try if I find one again.
The common name for this is Chicken of the Woods.
This is likely a type of button mushroom. The entire mushroom - or what's left of it - is about 7 mm. long. I once read that mushrooms have little nutritional value, but I have since then seen several squirrels and chipmunks eating them. I can imagine a little mouse nibbling on this one.
