Sadly, the title is misleading. "Know Your Mushrooms" is what the makers of the film want you do... it's not the subject. There is almost no material about identifying fungi, instead it's a puff-piece about the importance of mushrooms, even claiming that they are the basis of religion and that Jesus was a mushroom. All of the groundwork leads to a diatribe that seems meant to entice the viewer into trying "Magic" mushrooms.
If you want some fairly interesting random facts, it's OK...
If you want some talking points to justify drug use, it's pretty good...
