Fungi – The Hidden Kingdom

The mushroom on your pizza is just the tip of the organism, a temporary fruiting structure sitting above a vast, mostly invisible network that might stretch for kilometres underground. This episode explores fungi as their own kingdom of life, more closely related to animals than to plants, and covers mycelium networks, decomposition, the genuinely complicated science behind mycorrhizal partnerships with plant roots, yeasts and fermentation, the accidental discovery of penicillin, and fungal disease in both humans and wildlife.

You'll come away understanding why fungi are classified separately from plants, what mycelium actually is and why some fungal individuals rank among the largest organisms ever found, how fungi drive decomposition and nutrient cycling in every ecosystem, what's solid and what's overstated in the popular "wood wide web" idea, how yeast fermentation gives us bread, beer and wine, how penicillin was discovered, and how fungal diseases affect both people and wildlife such as bats and frogs.
