That is a really cool cooking tree. Unfortunately, it looks like a Coastal Live Oak that's been infected by sudden oak death (the stuff that looks like sawdust on the tree's bark). If so, it's not long for this world. I live not far from Inverness and the CLO in front of my house is infected and is going to be taken down soon. SOD is epidemic among Live Oaks in the North Bay. It's a very sad situation.
