Leaf litter is something one probably rarely looks too closely at but, out of this rotting material comes beautiful gems such as this stunning Magpie Fungus. By far my favourite fungi, this is common in southern England but, being an inkcap, it only presents in this immaculate form for a few hours before the caps start melting away in to an inky substance.
It apparently smells of naphthaline (ie moth balls) and is said "to be poisonous but eaten by some with no ill effects". Note, the book says eaten by some will no ill effects, it does not say what happened to the others!
In any event, who would want to pick and cook such a lovely structure. Is it not best left where it was found for others to see?
