The concept of biodiversity is often thought to be flora and fauna - but there's another 'F' word... fungi, which comprises a third forgotten kingdom.
Alison Pouliot is an ecologist, environmental photographer, natural historian and fungi fanatic, determined to change the way we understand fungi, which is so often misunderstood.
Alison's passion for all things fungi, have taken her rummaging through underbrush all around the world, teaching students, and publishing her findings in three books. The latest is Underground Lovers: Encounters with Fungi.
