In every woodland lurks a spirit, guardian over all . . .

Green Man with face fungus. When first I took his photo he had fungus hair as well. He must be getting old. Photo 11th October 2017
While the spirit-loci looks kinda heavy (a serious looking beastie) the sprites prefer to form themselves of light . . .

In fact, not a woodland, but a bank climbing beside a disused railway in Costessey (Norfolk UK). Photo 11th October 2017
As for this fella . . . I thought he looked much like a snake.
