Find out more about the fabulous world of fungi with some world experts in their fields.
This talk will provide the very latest insights into the use of mycoremediation - the use of mushrooms to clean and filter water - in a rapidly growing project being undertaken by Flete Field Lab CIC. Alice Sophia Pefanis and Honor Wolf are jointly offering this talk. They bring together expertise in mycology, fungal ecology, ecosystem restoration, and community engagement to support research, education, and practical environmental action.

Discover why your garden might be hiding more fungal life than you think. RHS expert and author Dr Jassy Drakulic asks whether typical gardening habits are silently suppressing an ecosystem that is already there. Drawing on recent field evidence, Jassy reveals what is really going on beneath our feet, and why it matters for tackling problems like Honey Fungus.
Come away with practical, low-effort changes for your own garden: what to leave alone, what to avoid, and how to invite fungi in as allies rather than threats. No mycology degree required, just curiosity about the hidden half of your garden.

Join Professor Lynne Boddy from Cardiff University for a masterclass introduction to the amazing hidden kingdom of fungi - a kingdom with more species than plants and vertebrates combined. Working unseen, fungi are essential to Earth’s terrestrial ecosystems, and without them we could not survive.
Lynne is a prominent scientist, prolific author and ardent communicator of the mysteries and importance of fungi.

Fungi have often been overlooked in conservation, as they are hard to see, hard to study and frequently underappreciated. However, there is a growing realisation that these unsung heroes need conserving too. In this talk, Cardiff University ecologist and lecturer Dr Sarah Christofides will introduce you to the fungal stars of a major new conservation effort and explain how you can get involved in helping to preserve them.

In this conversation, Professor Andy Letcher of Exeter University will discuss the cultural history of the magic mushroom, with a focus on the UK. There is renewed interest in the potential of psychedelics to address a number of stubborn mental illnesses, as well as a burgeoning psychedelic underground, driven especially by people travelling to the Amazon to consume ayahuasca in healing ceremonies. In this talk Andy will challenge many of the myths that have arisen around magic mushrooms, answering questions such as: were the builders of Stonehenge tripping and was Santa Claus originally a mushroom munching shaman?

Lee Davies is the collection manager for the largest, oldest, and most scientifically important collection of dried fungi in the world.
Kew Fungarium holds over 1.25 million specimens from all seven continents, representing roughly 60% of known global fungal diversity.
In this talk he will discuss his life and the remarkable fungi he has met, from his work at Kew to expeditions in Madagascar.

Join Rich Wright, a conservation mycologist with over 20 years' experience in fungal ecology, rare species translocation and cultivation, for a talk on rethinking decay in Britain's oaks. Having held posts at Kew, Cardiff University and Plantlife, Rich brings deep scientific and field knowledge to heart-rot, a process often misunderstood despite its huge value for woodland biodiversity. The talk draws on years spent among ancient oaks and their fungi, exploring what decay can teach us about the living world, and ourselves.

Prof Lynne Boddy
Lynne is Professor of Fungal Ecology at Cardiff University. She has taught and researched the ecology of fungi associated with trees and wood decomposition for 50 years. She is fascinated by the hidden parts of fungi - mycelia - and how they behave in the natural world, their aggressive interactions between fungi of other species, how their communities develop in wood, how they are affected by invertebrates that feed on them and by climate change.scription goes here

Dr Sarah Christofides
Sarah is a fungal ecologist and lecturer at Cardiff University’s School of Biosciences. She was first enthused about fungi by childhood forays, and as an undergraduate became fascinated by the complex interactions that shape fungal communities. Since completing her PhD on fungal-bacterial interactions during wood decomposition, Sarah has worked on a large range on fungal research topics and is currently leading a major project on evidence-based conservation for endangered British fungi.
