If you’re a mushroom lover like me, you’ll want to check out New Seasons this weekend. Their expo this week is devoted to the fungus, and this week’s flyer promises each store will feature Shitake, Crimini, Agaricus (nee white button), Portabella, Wild Lobster, Chanterelles, Black Oyster, Alba Clamshell(?) and Trumpets.

New Seasons demos run from 11am to 5pm on both weekend days.

According to flyer (”Did You Know?”), the largest living organism ever found is the honey mushroom — called Armillaria ostoyae. It was discovered here in Oregon in the Blue Mountains, covers 3.4 square miles and is still alive and growing. It is an estimated 2,400 years old.

If you could make a risotto out of it you could cure world hunger.
