I found this King Penguin for my collection
whilst foraging in bookshops
in Hay on Wye.
Never take risks with potentially poisonous fungi.
Always consult an expert,
or a photographic guide.
My book is very charming,
but not really adequate for reliable identification.
There is much good advice online,
in France or Eastern Europe you can take them
to a pharmacy to be checked
and if in doubt
don't eat it !
