False morels are also edible and commercially sold as such in several Scandinavian countries, they just need fairly elaborate preparation and even that doesn't get rid of all the toxins.
Beefsteak mushrooms are pretty common in Michigan, and not really what I would call a false morel, as they aren't very similar (I'm sure they do get called that though).
I always referred to Verpa as false morels: https://en.wikipedia.org/wiki/Verpa
