Mushrooms are the fleshy, bulbous, fruiting bodies of fungi. All mushrooms are fungi, but not all fungi are mushrooms since not all fungi produce fruiting bodies.
Much like the seeds of a flower, the mushroom’s fruiting body produces millions or even billions of microscopic spores which allow the fungi to spread.
During the Devonian period, 360 million years ago, before the evolution of trees, giant megafungi known as Prototaxites colonised the earth, standing at a colossal 8 meters tall.
