Close Encounters of the Fungal Kind a new book from the scientist, mycologist and mushroom twitcher Richard Fortey, who travels Britain and Europe hunting fungi.
He found a fiery milkcap mushroom, from which “white milk” leaked. He put a drop into his mouth and at first “I had an almost sweet sensation … followed by the most intense combination of heat and pepper I have ever experienced, that seemed to expand beyond my tongue to occupy my whole head. Nor did it fade quickly.”
