"Why are some fungi helpful and others harmful?" asks Paul Glaister in Reading. Rutherford and Fry try to outdo each other with fungal top trumps to get to grips with the answer.

Decomposition ecologist Lynne Boddy, Professor of Microbial Ecology at Cardiff University, helps Hannah calculate the amount of dead plant material we鈥檇 be buried in across the globe, if we didn鈥檛 have fungi to recycle it. And she describes her first fungal encounter in her student flat which was riddled with dry rot, and explains how without fungi, we wouldn鈥檛 have plants.

On Adam鈥檚 team is Curator of Mycology, Dr. Bryn Dentiger, at the Natural History Museum of Utah. Bryn tells Adam that he can鈥檛 think of a single food that doesn鈥檛 have some association with fungus. And the links are mostly positive rather than just mould on the top of your jam or rotten fruit in your fridge. He introduces Adam to the Humungous Fungus 鈥� the biggest living organism on Earth - and they get excited at the prospect of 20,000 different fungal sexes.

The pros and cons of fungi don鈥檛 stop there. Microbiologist Dr. Ada Hagan, in Michigan lists some of the fungal diseases we鈥檙e prone to, and the numerous drugs derived from fungi that help treat a whole host of common diseases.
