The total amatoxins concentration from carpophore of a . fuliginea collected in different development stages were studied . the result showed that the highest content of total amatoxins ( 23793 . 3 g / g ) was found in the carpophore with the cap free from veil but the gill concealed by veil and , the lowest content of total amatoxins ( 4674 灰花纹鹅膏菌不同发育时期的子实体毒素分析表明：以菌盖尚未充分展开，内菌幕即将破裂时的毒素含量最高( 23793 . 3 g g ) ，在凋萎时急剧降低( 4674 . 9 g g ) ，只有最高时的19 . 65 。
