Good call there, Lori. It's sure as heck not worth experimenting with mushrooms or fungi, as some/many of them contain neurotoxins. Very serious if you eat the wrong ones. Also, I have it from a good source that all mushrooms are fungi, but not all fungi are mushrooms.
I actually bought a whole book on mushrooms and fungi of Florida just a few years ago when I found white fungi growing underground in the leaf litter under my oak trees. I got all excited thinking they might be white truffles . . . not!! I wrote to the author of the book I had, and he invited me to send a sample to him. I also told him that the squirrels seemed to be eating the fungi, and he emphatically said NOT to assume that because a squirrel can eat it, a human can too.
Kelley, from a quick leaf through my book, I couldn't find anything that looked like your mystery fungi, sorry. What part of the country are you in?
