Fungi and lichens

Its bright red cap is famous, yet fatal poisoning from it is extremely rare.

Its toxins are not reduced by cooking, freezing or drying, so no kitchen step makes it safe.

Most of this fungus is never seen. Its honey mushrooms are only the surface fruit.

Button, cremini and portobello are the same mushroom, picked at different ages.

A wild mushroom that smells faintly of apricots.

Its cap and stem fuse into one hollow chamber, so the whole mushroom is empty inside.

An ant climbs down to a leaf vein and stays clamped there after the fungus kills it.

It is named for the shape of a wild turkey's tail feathers when they are spread.

Dip it in liquid nitrogen and it keeps breathing.

Its yellow-orange colour is a sunscreen, a pigment that shields the algae living inside it from sunlight.
