“The fungus doesn’t think,” she says. “But it remembers. And in a world of rapid change, memory may be more important than intelligence.”
What Dr. Hoshino discovered next rewrote forest ecology.
The fungus had acted as a , using stored data from past attacks to coordinate a defense. sugiuranorio
But they were wrong. It was not a killer. It was a librarian.
Dr. Hoshino’s current work involves transplanting Sugiuranorio mycelium into younger forests—trying to give them the memory they lack. It is a slow, careful process, like teaching a child the history of a war they never fought. “The fungus doesn’t think,” she says
Unlike typical wood-decaying fungi, Sugiuranorio did not break down cellulose or lignin. Instead, it grew into the tree’s phloem cells without killing them. It formed a permanent, living lattice between the cedar’s sap channels.
She hypothesized that Sugiuranorio was communicating with a wider network. The UV pulses, synchronized with the trees’ transpiration cycles, attracted specific species of parasitic wasps that preyed on bark beetle larvae. By summoning the wasps, the fungus closed the loop: chemical defense + biological control. Hoshino discovered next rewrote forest ecology
When Dr. Hoshino published her findings, the world took notice. Biotech companies raced to isolate Sugiuranorio ’s signal-storage proteins. They called them —molecules capable of encoding environmental data for over a decade within fungal tissue.
