Once upon a time I had a book about fungi identification that, of course, listed those to avoid because likely to make you sick or kill you stone dead. I recall that it mentioned St George's mushroom with the comment that this was the worst of the lot because it took 60 days for it's toxins to murder you!
Now, the question did occur: how was this 60 day delayed death detected? Perhaps the eater merely died of summick else co-incidentally? As with many such subjects, the literature is full of mere hackneyed opinions as well as well researched facts.

If you can add the source then I'll try and have a look.
There are some mushroom toxins that have a delayed effect eg orellanine:

But I'd want to check that it took 60 days from ingestion to any symptoms or signs rather than 60 days from ingestion to death. The latter would be in the right ballpark for many toxins causing irreversible damage to eg liver or kidney with medical treatment. And the earlier symptoms or signs would make the association easier to spot.

PS: St George's mushroom isn't usually described as containing toxins that are dangerous to humans.
The book that I have a memory of as warning agin' St George's mushrooms went to the charity shop a long time ago. The only reason I recall it is that it seemed a remarkable thing that a fungus could getcha two whole months after ingesting it! One of those memories that stick.
But other funghi books I've retained (because of better illustrations, layout, info and the like) don't, as you say, warn about St George's mushroom so perhaps I have a false memory; or the book itself was one of those compiled by a non-expert from other sources, which book-types are notorious for getting their "facts" twisted, as you will know. I do recall that book being something of a "popular" sort - large format, lots of pics, just a bit of accompanying text.
I've never personally come across a St G mushroom (that I know of). I did once have a collection of over a hundred spore prints - but they too went the way of such stuff when we made a house move. They were taken about 40 years ago, well before the advent of digital cameras, which would be a godsend to funghi-spotters today as one could have a photo of the mushroom but also it's spore print and associated notes, all in one neat file. (Mind, one would have to manage the colour space of the monitor, software and camera very carefully).
Although there are many hobbies and interests currently pursued in the Cugel household, mushroom hunting and investigation is now just a casual thing of collecting photos of the fascinating things when out cycling or dog walking. Perhaps I should revive the more detailed approach.
