Hi, ta for reply.. yeah but..

a) how come, if that’s true, insects don’t avoid Venus fly traps?

b) there might be mimicking going on – with some mushrooms looking like the ‘good to eat’ ones (eg death cap & Destroying angel – I love the names – looking like eg field mushrooms), so are harder to avoid

c) “if an animal is killed by a poisonous mushroom, it will not be able to eat any more mushrooms” – good point, so maybe some have evolved to make an animal only vomit, & spread the spores that way
