There are thousands of mushroom species out there. Some are super tasty, some edible but not worth eating, and some so poisonous that they can make you extremely sick, or worse. Get yourself a good mushroom guide and identify a mushroom in your area.
Spore prints are great for helping you figure out what mushroom you have, collecting spores to propagate, or just for some cool artwork to hang on your wall! Take a picture of your spore print along with the mushroom that made it. This project solves a challenge for the Mycologist Skill.
