30 | Foraging: Hunting for mushrooms has become a passion in the West, as foragers scour damp forests, mountain peaks, and coastlines for the coveted caps. To safely join in the adventure, check out a mushroom club near you (namyco.org for listings). Or sign up for Healdsburg, California’s Relish Culinary Adventures (relishculinary.com), where you forage and then cook up your haul.
31 | Dinners: Menus here are the most fungi-friendly in the country. We like Poggio Trattoria ($$; 415/332-7771) in Sausalito, California, which celebrates the rainy season with dishes like porcini pasta and pizza with chanterelles.
32 | Festivals: Mushroom festivals are weird and wonderful things, mostly happening in late fall and winter. Get your feet wet at California’s Mendocino County Wine & Mushroom Festival (visitmendocino.com) in November. In late January, Oregon fetes its most famous fungus with the Oregon Truffle Festival (oregontrufflefestival.com), which hosts seminars and dinners in and around Eugene.
