Snip

. . . . . . However...today I
took the vinyl off to put a layer of hay on top and found to my
astonishment
loads and loads of mushrooms(?) fungus(?) toadstools(?) no idea what they
are!..They stand about 6"high and are grey with an open flat grey/black
top
on them. Where on earth did these come from? and how, if it were hot
enough
to create steam did they survive?...will they go or am I stuck with a
large
heap of unusable compost?

Thanks again

Shan,

Without fungi we would be in a really sorry state. Just imagine, nothing
would rot very well.

It's OK and just what you need in a composter. Sounds like you've put horse
manure in there.
