Gosh, are they really that rare? We used to go mushrooming when I was little back in Australia and fly agaric seemed to be reasonably common — at least, we usually saw a few. Never thought of calling them after Enid Blyton, but it's a fitting name! (And no, you definitely don't eat them. They cause hallucinations, apparently.
)
I'm impressed that the blogger in the second link was finding them "in the Gippsland region" — which is where I come from!
— although he could have been a
little more specific. Gippsland is almost the whole of south-eastern Victoria, pretty much everything east of Melbourne and south of the Great Dividing Range — a mere 16,045 square miles, going by Wikipedia!!
Probably plenty of mushrooms and toadstools (EB Red and otherwise) within that area...
