This was not an encouraging opening for a conversation. Alice replied, rather shyly, 'I - I hardly know, Sir, just at present - at least I know who I was when I got up this morning, but I think I must have been changed several times since then.'
'What do you mean by that?' said the Caterpillar, sternly. 'Explain yourself!'
If we were to choose one mushroom to stand for all mushrooms would it not surely be this? The Fly Agaric. The archetype 'toadstool' with its blood red cap flecked with white and its snowy gills has gone beyond being a mere living organism. It is a totem, a potent emblem branded into our consciousness from infancy through countless tales of folklore and fairies. From the brothers Grimm to Angela Carter, wherever there are wolves and woodcutters and wicked stepmothers it's a fair bet the Fly Agaric will be painted somewhere into the backcloth.
There's no doubting that the Fly Agaric, Amanita muscaria, is cousin to some very dangerous mushrooms indeed. The large genus includes some notorious serial killers; the unambiguously named Death Cap, Amanita phalloides, and the beautiful ghostly white, and altogether more poetically named Destroying Angel, Amanita virosa. Between them these species account for the great majority of mushroom fatalities in Europe. The aforementioned guidebooks like to dwell on the gruesome symptoms, the delayed onset of which means their cocktail of toxins has already set about turning vital organs to soup before we know we need help.
When Alice encounters the hookah-smoking caterpillar who befuddles her with existential questioning, it is perched on a mushroom. John Tenniel's illustration isn't obviously a Fly Agaric but Lewis Carroll's text makes it plain he has an hallucinogenic fungus in mind. As a parting shot the disdainful caterpillar (the perfect shape shifter of course) advises Alice that eating one side of the mushroom will make her grow larger, the other side smaller. Dimensional mind-bending is apparently a commonly recorded experience of those who have indulged.
Fly Agarics are widespread in temperate mixed woodland across the northerm hemisphere. In the right conditions they can be locally common, as I encountered walking in Hamsterley Forest, County Durham, last week. There had been days of rain and mushrooms of all shapes and sizes had truly inherited the earth. The fruiting bodies of the Fly Agaric begin life above ground as tight buds enclosed in a white veil. When the veil ruptures fragments remain on the cap giving its typical warty appearance, but they may wash off in heavy rain. As the cap opens the gills separate from the stem leaving a white ring, or annulus, but again this is not always present. Old specimens become flat and paler in colour, often full of holes where they have been eaten by insects, molluscs and even small rodents.
