Oh, they are for sure beautiful. And the red ones (and yellow) aren't that poisonous, they only contain stuff that causes anticholinergic effects, ie, delusions and hallucinations, but most likely won't kill you, and their effect is greater if you gently toast them.

But unless you want to see people who aren't there and other such things, best to avoid the whole family, and they all have white gills. The pure white ones have a poison in them that takes 3 days for the liver to metabolise, at which point you drop dead of liver failure.

So be careful, never eat anything you aren't 110% confident is a species you know to be edible. Most of them are! Most are just not very tasty anyhow.
