During the rainy winter, the Mendocino Coast Botanical Gardens is home to more than 100 species of wild mushrooms. Every Monday at 1:30 p.m., naturalist and mycologist Mario Abreu takes visitors on a mushroom tour, pointing out the different varieties and talking about mushroom lore. The walks are free with admission, which is $8–$15 (free for ages five and younger). Reservations are required; go to gardenbythesea.org/calendar/mushroom-walks.
