Lone fly agaric toadstool I noticed at the start of this month, growing in the grounds of Compton Hospice right by the main road. December is a little late for mushrooms of this species.
The first two pictures in this set are of the same mushroom, taken from slightly different angles. They were taken on December 1st, probably the day it emerged. The other pictures are of the same mushroom three days later, again from two different angles.
It was only when I got home and compared the pictures that I realised there had been any growth at all.
