This bad boy has enough amatoxins to painfully and slowly kill you( Slaps cap emphatically). The all white appearance is wonderful on these, all I can think of is a ghost.

I am not sure on the exact species as there are a handful of closely related ones in NW Indiana. I did not take it home to break out a microscope or KOH, so we will have to survive without.

Now I am curious if whatever slug munched on this is toast, if any slug specialists out there want to fill me in I would appreciate it.

Bonus Cinnamon chanterelle, another bright red mushroom that looks out of place.

Why does it look like someone took a bite out of it?

Well how else was OP going to identify it?
