Toadstools.

You never see them

pushing through the ground

as green shoots do

before the flower breaks forth.

It seems at night

they find a spot

and ARE,

so that

coming to the field in

the cool of the

Autumn morning,

their pointed domes,

smooth and shining,

their pale stalks

huddled together for support,

are there in the grass.

Catch them with your foot

and they collapse.

See them next day

and they've become

a sticky foetid mass.

But just for one day

you really feel

they could be hiding

pixies!
