Piedmont Mycological Society through MeetUp.com: “This group is for anyone that enjoys learning about fungi. We’re made up of novices, experts and everything in between. We forage wild mushrooms, identify them, learn about them, talk about them, grow them, cook with them and eat them (only the safe ones)”.
The Piedmont Wildlife Center in Durham offers classes called the Wild Harvest Series. Foraging expands beyond mushrooms to a multitude of edibles provided by nature. Instruction and dinner is provided or you can elect to join for dinner only.
