Gandalf Mushrooms

An extraordinarily wrinkly mushroom found in the lands of North America. This mushroom resembles the lower chin of an extremely old man, and is said to have the wisest powers of them all but fends off its opponent by its unattractive, war-torn, wrinkly chin and mouldy cap. This lad has seen it all. It will only appear when the picker is specifically supposed to be doing something and accidentally comes across it.
I was supposed to be beating rose and blackberry brambles but got distracted by these huge Gandalf Mushrooms
