Remarque<\/p>\n<\/div><\/div>\n\n\n\n

Thermophile. Tr\u00e8s proche de Amanite ovo\u00efde, comestible, elle s’en distingue par sa volve color\u00e9e. Elles poussent dans le m\u00eame biotope. Il faut \u00eatre tr\u00e8s m\u00e9fiant. Dans la litt\u00e9rature on peut parfois trouver Amanita proxima d\u00e9crite comme une vari\u00e9t\u00e9 de Ovoidea. La biologie mol\u00e9culaire a prouv\u00e9 que ce sont des esp\u00e8ces distinctes.
Dans les cas o\u00f9 seule une partie du pied a \u00e9t\u00e9 ramass\u00e9e, il est difficile, voire impossible de conclure, car le voile g\u00e9n\u00e9ral est caract\u00e9ristique mais parfois absent. La toxicit\u00e9 des champignons \u00e0 amanitine est suffisante pour \u00e9liminer du panier tous les champignons en contact avec ceux-ci.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n
