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.
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.
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.
