FFungi

Fungi are eukaryotes with chitin walls that digest food outside the cell. Yeasts, moulds and mushrooms are lifestyles inside one kingdom — not three unrelated pests.

They invented much of terrestrial recycling and quietly feed plants through mycorrhizae. A minority cause athlete's foot, asthma flares or hospital mycoses.

This atlas treats fungi as a tree-of-life branch. Food crafts, soil allies and pathogens sit in later human and everyday sections — never as a foraging guide.
