Over the centuries, they’ve been used for food, folk remedies, dyes and psychedelics. They come in all shapes and a variety of colors, still most people are only familiar with the mushrooms they see in the grocery store produce aisle. On Saturday, May 7, North Texans will have the opportunity to learn all about mushrooms, including those that grow in our region, by attending, “The Underground World of Mushrooms,” a workshop hosted by the Botanical Research Institute of Texas in Fort Worth.
