Before you spot a single mushroom cap, an entire hidden kingdom is already at work beneath the forest floor. We begin by breaking down the core biology and identification groups that help you recognize fungi in the field.
This call starts with the basics of fungal biology and the major identification groups used in the field. Participants will learn how to recognize agarics, boletes, polypores, puffballs, jellies, cups, and other common forms through clear photos and simple diagnostic features. From there, the program moves into fungal ecology—how fungi decompose wood, form symbiotic partnerships with plants, and build the underground networks often called the wood‑wide web. The class concludes with a nod to fungi’s cultural and practical significance: edible species, poisonous lookalikes, and the medicinal and biochemical compounds that have shaped human history, from penicillin to modern psychedelic research.
An optional outdoor foray extends the learning as the class practices real‑world identification.
