Uh - don't look now, but you just agreed with a probable cause of that natural selection.
I don't see the point. I have never agreed that Natural selection is the cause of mushroom's coloration. If I agreed that toxicity of mushrooms is probably detected by wild animal by smell it would not necessary mean that I agree with NS as source of it either. It's only your logic you know.
Toxicity of mushrooms is another puzzle. I have mentioned Lethal webcaps. Digestion of this mushroom will destroy your liver - but sometimes first nuissances are detected only after 3 weeks. Anyway the poison will kill the animal that had eaten the mushroom. Obviously such type of poison was not created and maintained by Natural selection. It has no sense - no animal would be able to make relation between mushroom eating and its nuissance after so many days.
I have mentioned already Amanita muscaria as very delicious mushroom, Amanita phalloides as most poisonous one and strangely enough - Amanita muscaria with its toxic effects. Due to its toxic effects the muhroom is sought for by some species (deers) and the others (didelphis) are avoiding it. So to find any darwinistic explanation of such diverse "survival strategy" in the same Genera is very difficult. To find out darwinistic explanation of toxicity of Amanita muscaria is impossible.
That's the reason why this thread is dying. Neodarwinists after first research - at least the intelligent among them - see that my point is correct. Natural and sexual selection as the cause of mushroom's coloration is wrong and misleading explanation (and of toxicity as well).
I could not answer, but should maintain my ground.-
