i do think a lot of people get anxious about fungus and its potential toxicity, but there are only 6 species that can potentially kill you and thats out of 100s in britain.
Hmmm.... Some of those six are rather variable and others are very easily confused with things that are edible. And we don't know that there only six, either. The edibility/toxicity of the vast majority of fungi is
unknown. There are, for example, hundreds of British species of
Cortinarius, some of which are known to be deadly, several to be seriously poisonous, one known to be edible and the rest could be either edible, deadly, or anything inbetween. Who is going to be the guinea-pig? On top of that they are very tricky to identify and therefore potentially under-reported rather than being as rare as the records suggest they are.
So there's two sides to this story, I think. The majority of fatal mushroom poisonings, worldwide and in the UK, are the result of just two species: the Death Cap (
Amanita phalloides) and the Destroying Angel (
A. virosa). The other two which regularly kill people are
Galerina marginata and
Clitocybe rivulosa. In all these cases there is a combination of deadly poison and serious possibility of confusion with something commonly eaten. But I think if people started to get the idea that once they've learned to avoid these species then they are pretty much safe to experiment then they are likely to end up in serious trouble of one sort or another.
