Stinkhorn Fungus "Eggs"
I found these yesterday, on a well-rotted tree trunk on the ground, in local woods. The mature fungus has a foul smell of decay to attract flies which then distribute its spores. These are actually edible and a sought-after delicacy. They were in a reserve so were photographed in situ and left where I found them. They are popularly known as "Witches Eggs" or "Devil's Eggs".
They were about the size of ping-pong ball and looked much like the texture of turtle eggs.
They were pure white so I have darkened the images considerably to show detail.
The stereo is crosseye.
