Join Maine Master Naturalist Merrie Eley on National Mushroom Day with special guest, mycologist David Porter, to explore the beautiful trails of Blue Hill Heritage Trust’s Patten Stream Preserve. We will search for mushrooms and other natural delights along the 1.5-mile walk. Sturdy walking shoes and hiking poles would be helpful. Sponsored by Downeast Audubon.
