What is this? I'm out all of the time but I've never seen one of these before. It appears to be some kind of mushroom or puffball. There was a group of about five of them and they were about 3 inches in diameter. They were growing in an oak woodland, Santa Monica Mountains (Los Angeles County), California.
What Is It?
It appears to be the puffball Calbovista subsculpta.
That's the most beautiful puffball I've ever seen! I bet it's edible and delicious!
Puffballs are one of my favorite woodland edibles.
