@tippitiwichet If it's any comfort to you, I'm in my mid-40s and only just learned about polypores, too. Got into mushroom growing a couple years ago. Biology classes spend little time on fungi, and growing them is still a pretty niche subset of gardening. Learning is a lifelong process... Great pictures!
@HaikuHedgehog An oyster mushroom kit totally started all of this :). Oyster mushrooms now help me recycle my Amazon box cardboard. And thank you :)
