I was out mushroom hunting yesterday for morel mushrooms and came across an area with many old and fallen trees. It just so happens that this area was perfect for the mushroom called "pheasant's back". They are also sometimes called "Dryad's Saddle". You can see why they are called pheasant's back due to the design on the mushroom. I ended up picking 9 lbs. of them and left many more behind. The younger ones are preferred because the toughen with age. All the ones in my photos were still soft. I was reading on the best way to cook these and found that frying them up in bacon grease makes them taste great.
I found these in a secret location near Elgin Illinois. Never give away a secret location or you will not have mushrooms the next year! I did see one other person hunting mushrooms but he was about a 1/4 mile away and I'm sure he didn't see me. If you're interesting in hunting mushrooms I put together a list of equipment that will make your hunt mush more enjoyable.
