This presentation is focused on visible ‘macro' characteristics of amanitas. If you were Amanita expert Rod Tulloss, you would combine your knowledge of the morphology of amanitas with chemical tests, microscopic analysis and genetic testing to help definitively identify them. If you have a mushroom with white spore and free gills, it is either a Lepiota or an Amanita.
This describes a combination of characters that exits for relatively few amanitas. It is sort of a composite of Amanita virosa and Amanita muscaria. 002-001
