they did redden a bit. They were a bit dry already though.

If they're dry they won't discolor as much? I was all set to try a blusher. All the defining features were there but I cut it open and it didn't turn pink. It might have been dry...

I always find them in mulch landscaping which probably means there are pesticides and other toxins absorbed into them

Apparently that's where winecaps are found most often and the sources say the same thing about pesticides. Probably not a good idea to eat them.
