On heathland or the woodland floor you will see a variety of fungi emerging especially in a damp year. The massive networks of fungal mycelia in the leaf litter and topsoil are producing lots of fruiting bodies that produce reproductive spores.
They appear at astonishing speed.
Amongst the fungi you may spot are:-
The fly agaric
It is almost unmistakable, with its red or orange cap and cream/white spots.
This fungus is very commonly seen in woodland and heathlands.
For many people it is the archetypal toadstool and looks like the ones pictured in children's books and nursery rhymes.
The common name stems from the tradition of using this fungus as an insecticide. In some countries the caps are put into milk and any flies attracted die from the toxins that are dissolved from within the mushroom.
