Humongous Fungus

Their beautiful mushrooms come in all colours, shapes, and sizes. Fungal stories include the greening of the Earth, when fungi helped plants first grow on land, and the mass destruction of crops through fungal disease. From the villains of the upcoming bananageddon to plastic-eating eco-warriors, there are over 1.5 million known fungus species, and a huge, unknown number of unnamed "dark" types. Some are even found inside animals - helpful fungi break down food in animal guts, but others take over their hosts' bodies.
