For nearly forty years, the Colorado Mycological Society's annual Wild Mushroom Fair has celebrated the joys of fungi; it will pop up again from 11 a.m. to 5 p.m. on Sunday, August 20, at the Denver Botanic Gardens, 1007 York Street. Marvel at a massive display of wild mushrooms of varying shapes, colors and sizes while learning how to identify certain species from on-site experts. You can also find out how to cultivate and cook mushrooms, even how to photograph them in a natural setting. Young fungi fans will have their own “kiddy korner.” The fair is included with standard DBG admission fees of $12.50 for adults and $9 for students and children.
