Fungi fans, cap off your week with a trip to the 44th annual Mushroom Fair, Sunday, Nov. 13, from 11 a.m. to 4 p.m. at Arcata Community Center ($5, $1 kids 12-16, free for kids under 12). Find out who’s shroomin’ who with presentations and exhibits on 350 species, mushroom identification. You’ll learn which ones are edible and which ones are no-nos. You can even bring your own to have identified by the pros. And bring some moolah, too, so you can take home cool mushroom cultivation kits, books, art and T-shirts.
