Thanks, @pridefoltz! With that crusty orange-red exterior, it would be hard to confuse a lobster mushroom with anything else -- but there's no telling what some folks can get confused about, lol. I think the harder part for this wild mushroom is being able to tell when it is in good shape vs. when it's too old, since people don't get much practice with that, and the guidebooks don't show that kind of stuff. I look for a firm, bright-white interior. At least, at your Whole Foods, you can look and get to know the mushroom without having to buy it! :D
