毒蝇伞 (L.:Fr) Pers 九种基因型的能力。在无菌液体培养物中检查了利用一系列无机和有机氮源进行生长的方法。所有基质上的生物量产量均观察到相当大的种内差异；然而，对于所有基因型，谷氨酰胺和/或 NH4+ 的生物量产量最高。天冬氨酸、谷氨酸和组氨酸的产量相对于 NH4+ 而言普遍较低，而精氨酸和甘氨酸的利用率在基因型之间显示出显着的差异。八种基因型在牛血清白蛋白上产生的生物量显着低于在 NH4+ 上产生的生物量，这引发了关于将毒蝇伞分类为“蛋白质真菌”的问题。
The abilities of nine genotypes of Amanita muscaria (L.:Fr) Pers. to utilise a range of inorganic and organic nitrogen sources for growth was examined in axenic liquid cultures. Considerable intraspecific variation was observed in biomass yields on all substrates; however biomass yield was highest on glutamine and/or NH4+ for all genotypes. Yields on aspartic acid, glutamic acid and histidine were generally low relative to NH4+, while utilisation of arginine and glycine showed marked variation between genotypes. Eight genotypes produced significantly less biomass on bovine serum albumin than on NH4+, raising questions regarding classification of A. muscaria as a 'protein fungus'.
