What is Entangled Life: How Fungi Make Our Worlds, Change Our Minds and Shape Our Futures about?

Merlin Sheldrake is a biologist who has spent his career studying fungi, and Entangled Life is his account of what fungi are, what they do, and why most people who think they know something about the natural world understand almost nothing about this kingdom of life. Fungi are not plants. They are not animals. They predate both, they are more closely related to animals than to plants, and their ways of existing in the world challenge almost every intuition humans bring to thinking about life.

The book is organized around the different things fungi do rather than around taxonomy. Sheldrake covers mycorrhizal fungi, which form symbiotic relationships with the roots of roughly 90 percent of plant species and have shaped the evolution of terrestrial plant life for 450 million years. He covers lichens, which are symbioses between fungi and photosynthetic organisms and represent some of the most extreme survivors on Earth. He covers the wood wide web in more rigorous detail than Wohlleben, grounding the claims in the specific experimental evidence and acknowledging what remains contested. He covers psilocybin-producing fungi, the history of ergot and its role in the Salem witch trials, and the fungi that control ant behavior in ways that look like something from science fiction.

The writing is genuinely good — lucid, curious, willing to sit with uncertainty rather than resolve it into false clarity. Sheldrake is honest about what science knows and doesn't know about fungal cognition, fungal communication, and the degree to which mycorrhizal networks function as information systems rather than mere plumbing. He also writes about fungi that are breaking down plastic waste, fungi that might be used in building materials, and the genuinely plausible possibility that mycelial networks process information in ways that are not yet well understood.

Entangled Life is the best popular science book on fungi because it refuses to oversimplify a kingdom of life that is genuinely strange. Sheldrake's background gives him the authority to engage with the frontier science, and his intellectual honesty makes the book more interesting than confident popular accounts that paper over uncertainty with enthusiasm.
