Greg Marley will lead a mushroom identification and collection workshop at Merryspring Nature Center in Camden on Saturday, September 15, from 9 a.m. to 3 p.m.

Marley’s day-long outdoor class will help participants build the skills to identify common mushrooms, including well-known edibles, poisonous species, and useful medicinal varieties that can be found in Maine’s forests (pictured are chanterelles). Marley has been collecting, studying, eating, growing, and teaching about mushrooms for over 40 years. He is the founder of Mushrooms for Health, as well as the author of “Mushrooms for Health,” published by Down East Books (2009), and “Chanterelle Dreams, Amanita Nightmares,” published by Chelsea Green (2010).

Guests should wear weather-appropriate clothing and sturdy shoes and bring a bagged lunch. The cost of the workshop is $70, with a discounted rate of $60 for members of Merryspring. Pre-registration is required. The program is part of the Weekend Workshop series at Merryspring, which is at the end of Conway Road, just off of Route 1 in Camden behind Hannaford Plaza.
