In mycelial worlds, plant roots and fungal networks form vast underground alliances, exchanging nutrients and chemical signals in what’s often called the “wood wide web.” Like roots are blood capillaries and fungals as neurons, this living network circulates resources and information across entire ecosystems. Through these connections, trees can feed shaded seedlings, warn neighbors of pests, or even share medicinal compounds. This symbiosis is so efficient that some plants rely almost entirely on their fungal partners for survival, blurring the line between individual organisms and a collective intelligence beneath the soil.
