The mystery of the mushroom

I bet you’ve always wondered
why & when field mushrooms grow
Well I shall let you into a little secret
but don’t tell the world, it’s not to know

I heard whisper’s within a windy wood
howling thru the forest trees
I climbed inside an old mossy stump
crouching on my knees

As I watched from within my hidey hole I saw a flock of sheep,
herds of Highland cows decended from yonder hill so steep

Each & every animal entered the farmer’s land
they congregated in a circle as if disgussing what was planned

Then a chosen selection of them
from both the different beasts
scattered amongst the wet grassland
heads down munching their favourite feasts

As they stored their stomaches
so full with green fresh grass
an over-powering odour filled the air
a stench of foul methane gas

I nipped my nose but I was mesmerized 
as I gazed amidst the grassy sight
In minutes this entire green pasture was covered in small balls of white

Mushrooms appear overnight
when humans are asleep
Now you & I know who are responsible
It’s the Highland cows & woolly sheep
