I don't know about other ferns. And no, I have never tried them. I would like to though.
I was always looking for morels when I would see them.

I'm not much of a forager, but would like to get into it more. We do have a garden. What's an easy thing to find and ID that's yummy? The existence of toxic mushrooms has me wary. 🙁
Morels are pretty hard to misidentified. There is something called a false morel, but it doesn't even really look the same and it isn't hollow like a morel is.
