Destroying angels are a mushroom which live up to their name. Beautiful to look at, but deadly to eat. Also possible to confuse them with perfectly edible species: these were almost pure white, but they are often browner. Then they look a little like the field mushroom (the wild version of the common or garden supermarket mushroom).
Just below ground level, destroying angels have a volva, a sac that the fruiting body is growing out of.
These specimens had been imported into Northycote Farm in a batch of wood mulch. They were photographed just before they were removed for safety by farm manager Ian Nicholls – it’s his hand holding the one toadstool with a slight brown colour to the cap.
