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

R\u00e9action jaune \u00e0 la potasse avec la vari\u00e9t\u00e9 decipiens<\/em>. Il faut une vigilance constante lors du ramassage des champignons blancs dans les bois.
Dans tous les cas o\u00f9 la totalit\u00e9 du pied n’a pas \u00e9t\u00e9 ramass\u00e9, il est difficile, voire impossible de conclure, car le voile partiel et g\u00e9n\u00e9ral est caract\u00e9ristique mais fragile.
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
