The stormy January deluge means one good thing for February: lots of mushrooms sprouting up everywhere. At the Seeds and Reads: Mushroom Models class, children can learn about the varieties of fungi that grow locally, and even how to make a clay mushroom model. Created for kids in kindergarten through sixth grade, the free class will be held on February 21, 4–5 p.m., at the Petaluma Regional Library in Petaluma. Registration is required; go to tinyurl.com/nhmyaf95. The class will be held throughout February at multiple library branches. Check out tinyurl.com/bdfjw94p for the full schedule.
