There has been debate in the Australian media about hiding the location of poisonous fungi following the conviction of a person for murdering three others using Amanita phalloides, or death caps.
Here is a link to the article.
I found it interesting that the article talks about this debate about whether they should be obscured or hidden altogether, and there was an interesting discussion a couple of months ago that included this.
My feeling is that dissemination of information about poisonous species is likely to save more lives than hiding it, and that accidental poisonings are a far bigger problem than murder.
How do others feel about this?
