“When trying to understand the interactions of nonhuman organisms, it is easy to flip between these two perspectives: that of the inanimate behavior of preprogrammed robots on the one hand, and that of rich, lived human experience on the other.

Yet the mycelium of truffle fungi, like that of most fungal species, actively senses and responds to its surroundings in unpredictable ways.”
