Their work reveals that muscarine, another compound hallucinogenic to the mammalian brain, has been produced in the fruiting bodies of fungi for 60 million years.

他们的研究发种对哺乳动物大脑有致幻作用的化合物——毒蕈碱，已经真菌的实体中产生 6000 万年。

Many species within this family have conserved the alleles required to synthesizing muscarine until the present day, with a smaller subset of living genera within this family to lose this trait.

这个家族中的许多物种直到保留合成毒蕈碱所需的等位基因，家族中只有小部分活的类属失去这种特性。

In these two genera, the alleles that allow the synthesis of muscarine, have been completely lost, or silenced.

这两个类属中，允许合成毒蕈碱的等位基因已经完全丢失或静默。
