Winter Mushrooms at Indian Tree

Finally, local foragers and amateur mycologists can rejoice. The recent rains mark the late start of something else -– mushroom season. Did you know that the biggest organism in the world is a fungus? In 1998, scientists discovered a honey fungus that measured 2.4 miles across in the Blue Mountains in Oregon. Up until that time, it was believed that the 110-foot-long, 200-ton blue whale was the biggest. And based on its current growth rate, the fungus is estimated to be 2,400 years old, but could be as ancient as 8,650 years. If you want to get a closer look at some of these amazing organisms, come along on the hike through Indian Tree Preserve this weekend. The mixed forests of this Novato preserve usually host an amazing array of mushrooms at this time of year. With luck, you can make it to the top where you’ll get to enjoy spectacular views in every direction (Distance: 6.5 miles; elevation gain: 1,300 feet). Remember to bring enough water and food. Bring binoculars, if you have them. This walk is for ages 15 and up. We request that no pets (except service animals) attend. Rain may cancel.
