The risk would be consuming something that is not Psilocybe semilanceata, but poisonous enough to be lethal. Statistically, that wouldn't count as a fatality from it, but from whatever mushroom was consumed instead.

Should have been more precise, I meant fatalities from Psilocybe or little brown mushrooms that look like them.

Looking at statistics for a part of Germany (2006) again, there weren't actually any fatalities but 'only' cases of poisoning.
