I actually thought about that, especially the Morels-so good! However decided against a few that had extremely dangerous look a-likes or that take a fair amount of prepping. Mainly because I've based this around hikers on the Appalachian trail miles from civilization.
BUT some I've listed do have scary look a-likes...like the Chanterelle's however I felt maybe they're well enough known. It was a toss up. * lol*

I also wanted to add my favorite wild carrot (AKA) Queen Anne's Lace, but just the tinniest bit of it's look a-like the Poison Hemlock can cause death. Queen Anne however has a single tiny purple flower in the its center and unlike its look a-like, has a tons of root looking hairs at the base of the blooms. They both smell like carrots however. Wouldn't want to mix those up while out in the middle of no-where. Below Queen Anne's Lace

All great additions though for sure, and anyone looking to learn more should most definitely look into them.
