No, it's simple, you said it yourself, it was years before 'you' found one and it's not as though you've never been mistaken. We all do it, thankfully none of us have ever had more than a slightly queasy/wind filled tummy from it, but a little circumspect courtesy over this fatality would not have gone amiss.
Most people are first shown what is "edible" or useful, not what is poisonous; simply because those are the ones they're interested in, and have actually had them pointed out to them.
Even then most never look beyond a few species; I know I don't, and I've been doing it for years. It's not our jobs, simply an interest.
If you're not prepared to be helpful in making sure that others are informed, don't make the situation any worse. I have removed the lady's name from your first post; I'd hate for her family to read that OP.
