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

Esp\u00e8ce responsable de 90% des empoisonnements mortels. Extr\u00eamement abondant lors d’ann\u00e9es pluvieuses. Il existe la vari\u00e9t\u00e9 alba avec un chapeau enti\u00e8rement blanc et la vari\u00e9t\u00e9 decipiens , blanche, avec r\u00e9action orange \u00e0 la potasse.
Dose toxique <\/span>: 1 champignon pour un adulte, \u00bc de chapeau pour un enfant.
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 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
