Even though amatoxins and phallotoxins have been well characterized in basidiocarps of Amanita species, to our knowledge no report of these toxins in spores of Amanitas has been published. Reversed phase HPLC was used to determine non-zero concentrations of alpha-amanitin (0.30 mg/g), and phallacidin (0.02 mg/g) in spores taken from white Amanita sect. phalloideae species. We did not find significant amounts of phalloidin in Amanita spores. We also report concentrations of these toxins from pileus and stipe tissues that are similar to previously reported values, lending support to the hypothesis that toxin concentrations in spores are much less than in other basidiocarp tissues.
尽管鹅膏毒肽和蝇蕈碱已在鹅膏菌属担子果中得到很好的描述，但据我们所知，尚未有关于这些毒素在鹅膏菌属孢子中的报道。反相高效液相色谱法用于测定采自白色鹅膏菌属蕈环族物种的孢子中α-鹅膏肽（0.30 毫克/克）和蝇蕈碱（0.02 毫克/克）的非零浓度。我们在鹅膏菌属孢子中没有发现大量的蝇蕈碱。我们还报告了从菌盖和菌柄组织中提取的这些毒素的浓度，与先前报道的值相似，这支持了毒素在孢子中的浓度远低于其他担子果组织的假说。
