Not an identifier app, but excellent regardless – Mushroom Guide - North America Review

Although this app is labeled as an identification app, there is currently a very limited number of mushrooms actually included (25 at the time of writing). I was a bit disappointed by this, as it wouldn't have much practical use in the field. However, this is a fantastic app if you just want some information about notable mushrooms. The layout is stylish, the illustrations are gorgeous, and the articles are flush with interesting information about each mushroom. If you just approach this app as a nicely laid out mycology gallery, it's superb.
