While most poisonous mushrooms do not have a green spore print, 99.5% of mushroom species with green spores are poisonous.
I thought it was 99.3%. :-) Does anybody have a source on this statistic, or should we consider it folklore? Until we've got a source (such as a mycology textbook or study) this sentence should be less definite.
- I believe it comes from a study cited/discussed under toxicity of mushrooms. Still, it is a statistic hard to ascribe any practical value to, since it really means 99.5% of the mushroom species looked at in the study (which may have been all or a majority of mushrooms). For any given mushroom-hunting individual, however, the number is likely to be 100% of the mushrooms they would encounter in their area. I say modify - Marshman 17:13, 26 May 2004 (UTC)
One rule of thumb for determining if a mushroom is poisonous may be a green or white spore print. While most poisonous mushrooms do not have a green or white spore print, all but a very few species of mushroom species with green spores are poisonous.Mycologists , however, would be quiteare reluctant to identify any mushroom from its spore print alone allthough the spore print are one of many characteristics used in determination.
- (Please forgive my poor english - English is not my native language.) This «rule of thumb» in the article is wrong and it is dangerous if it is not removed. A lot of deadly poisonus mushrooms do have white spores and some of them are allso quite common. As an example, a lot of the species within Amanita (Norwegian: Fluesopper) are deadly poisonus, f.ex. A. virósa (norwegian: hvit fluesopp), A. phalloídes (norwegian: grønn fluesopp, A. phanterína (norwegian: panterfluesopp) are all extremely poisonus and have caused death. There are allso many other examples of species that don't follow the above «rule of thumb» so I think there are no more bold and old mushroom-hunters left to argue against the «rule of thumb». I therefore removed the «rule of thumb» in the article and changed the text accordingly. --Jan Helge Salvesen 09:40, 24 Feb 2005 (UTC)
