Both mercury (Hg) and selenium (Se) occur in many mushroom species, but the morphological distribution of these elements during different developmental stages of the fruiting bodies is not known. Although Amanita muscaria can be consumed after suitable processing, they are often ignored by mushroom foragers, leaving an abundance for investigative study. Multiple specimens in each of six developmental stages (button to fully mature) were collected in excellent condition during a single morning from the same forested location and composited. With an average of 30 specimens per composite, and low temporal, spatial, and measurement uncertainty, the data are likely to be representative of the typical concentrations of Hg and Se for each developmental stage. Hg (range 0.58–0.74 mg kg^-1 dry weight cap; 0.33 to 0.44 mg kg^-1 dw stipe) and Se (range 8.3–11 mg kg^-1 dw cap; 2.2 to 4.3 mg kg^-1 dw stipe) levels were observed to vary during the developmental stages, and the variability may relate to the demands in growth. In common with some other species, the lower stipe concentrations may be consistent with nutrient/contant transport and support functions. Both Hg and Se levels were lowest during periods of maximum sporocarp growth. Selenium occurs at almost an order of magnitude greater levels than Hg. Due to its role in mitigating the effects of Hg toxicity, this property is of significance to those who consume the species either for nutritional, medicinal, or recreational purposes, although the losses of both these elements during processing are not known.

许多蘑菇物种中都含有汞（Hg）和硒（Se），但这些元素在子实体不同发育阶段的形态分布尚不清楚。虽然毒蝇伞经过适当加工后可以食用，但它们经常被蘑菇采摘者忽视，留下大量的蘑菇用于调查研究。在一个早晨，从同一森林地点收集了六个发育阶段（从开始到完全成熟）的多个处于良好状态的标本并进行合成。每个复合材料平均有 30 个样本，并且时间、空间和测量不确定性较低，这些数据可能代表每个发育阶段的汞和硒的典型浓度。汞（范围 0.58–0.74 mg kg ^-1干重上限；0.33 至 0.44 mg kg ^-1 dw 菌柄）和 Se（范围 8.3–11 mg kg ^-1 dw 上限；2.2 至 4.3 mg kg ^-1 dw 菌柄）水平为观察到在发育阶段会发生变化，并且变化可能与生长的需求有关。与其他一些物种一样，较低的菌柄浓度可能与养分/物质的运输和支持功能一致。在子实体生长最大时期，汞和硒的含量最低。硒的含量几乎比汞高一个数量级。由于其在减轻汞毒性影响方面的作用，这一特性对于那些出于营养、药用或娱乐目的而食用该物种的人来说具有重要意义，尽管这两种元素在加工过程中的损失尚不清楚。
