I just sparked an interest, a couple years ago. I'm still a novice. I heard somebody say one time, ( because it is overwhelming, impossible even, trying to learn them all ) "You don't have to learn them all, just learn the ones that you are looking for." That's what I do, because, different times of the year, certain ones pop out. Those are the ones I'm looking for. Usually, each type can only be found in a window of a few weeks, even a month or two, then, they're gone till next year. I can positively identify a handful of different types. Then I just ignore the rest. As I go, I'll learn more. It helps if some of your favorites don't have any look-alikes, harmful ones anyway.
Here in Pa., the "Hen of the Woods" and the "Chicken of the Woods" are what a lot of shroomers are looking for, now through, like Oct- Nov.? The "Chicken" has no look-alikes, and the "Hen" has no Harmful look-alike. Both are EXCELLENT eating. Below, is a short video that shows both. They like Oak trees. Next time you're out in the woods, keep an eye open. The guy in the video is LUCKY!
