In this four-part lecture series, explore the mysterious world of lichens—from their physiology and ecology to their prominence in art, food, medicine, and spirituality.
The slow-growing, symbiotic life forms we identify as lichens have been called many things, from tiny ecosystems to “fungi that have learned to farm.” Unobtrusive and mysterious, lichens' history, biology, and current relevance are often overlooked—though once you begin to notice these strange beings, you’ll wonder how you ever looked anywhere else. We’ll begin by studying their boundary-defying biology, touching on the complex and counterintuitive makeup of these ancient extremophiles. We’ll then trace the role of lichens in folklore, food, booze, and even deodorant, before touching on how they’ve inspired spiritual and philosophical thought—hearing from expert biologists, environmental artists, and activists along the way. By the end of this course, you’ll have a deeper understanding of the fascinating life and ecology of lichens, as well as an appreciation for the ways in which they’re inextricably and broadly connected to human culture.

Felicity Roberts is an herbalist, lichen specialist, food and cocktail writer, conservationist, textile artist, and passionate home cook. She finds joy in using low-tech, scientifically sound, and sustainable methods to grow, gather, and prepare food; make medicines; and create art. Her enthusiasm for the fungal world and her multidisciplinary approach to learning are matched by an eclectic knowledge base acquired from a decade spent hitchhiking, farming, cooking, and studying herbs and fungi all over North America—with notable stops in British Columbia, Texas, and Maine. She has been featured on NPR, contributes time to the IUCN's Fungal Red List project, and is an Atlas Obscura trip guide.
This lecture series is designed so students can participate live or watch a recording after each session airs. Sessions will take place live over Zoom, with dedicated Q&A segments for students to ask questions via video or chat. Within 72 hours after each session airs, we will email all enrolled students a recording of the session, which they can watch using a temporary password for up to ten weeks after the course concludes.
In most cases, instructors will use Google Classroom to communicate with students outside of class. While students aren’t required to use Classroom, instructors will be using this platform to post resources, discussion questions, and assignments, when applicable.
