In response to Judith’s comment and questions about the “mushroom house”
It is located a few yards behind the red brick house at the foothill drive of Mayowood.
I actually did spend time in it, contemplating what it was used for. Water did run down the domed inside and drained out in a circular system. Hopefully, someone reading this will know, or I will have to do some digging into what it was used for! I am assuming cold storage. There was also a larger one built into the hill behind Ivy, but not as charming as this one.
