(MD) (Anacostia Watershed Society) Join us for a Mushroom Night Walk with mycologist Serenella Linares. During the experience we will encourage people to use their natural night vision, or headlamps that have a red light on them. Feel free to bring your own; some headlamps/flashlights will be provided. For witnessing bioluminescence, all lights will need to be turned off. It is important to wear closed toed shoes, preferably hiking boots. Registration is required.
