The epiphany that mushrooms could help save the world's ailing bee colonies struck Paul Stamets while he was in bed. In 1984, Stamets had noticed a continuous convoy of bees" traveling from a patch of mushrooms he was growing and his beehives. The bees actually moved wood chips to access his mushroom's mycelium, the branching fibers of fungus. Decades later, he and a friend began a conversation about bee colony collapse that left Stamets ... puzzling over a problem. Bees across the world have been disappearing at an alarming rate. Parasites like mites, fast-spreading viruses, agricultural chemicals and lack of forage area have ... threatened wild and commercial bees alike. Waking up one morning, "I connected the dots," he said. "Mycelium have sugars and antiviral properties," he said. What if it wasn't just sugar that was useful to those mushroom-suckling bees so long ago? Research published Thursday in the journal Scientific Reports ... describes how bees given a small amount of his mushroom mycelia extract exhibited remarkable reductions in the presence of viruses associated with parasitic mites that have been attacking, and infecting, bee colonies for decades. To test Stamets' theory, the researchers ... separated two groups of mite-exposed bees into cages, feeding one group sugar syrup with a mushroom-based additive and the other, syrup without the additive. For several virus strains, the extract "reduced the virus to almost nothing," said [researcher] Brandon Hopkins.
