Beringian origins and cryptic speciation events in the fly agaric (Amanita muscaria)

Multilocus phylogenetic and nested clade analyses of Alaskan and global samples show that Amanita muscaria sensu lato comprises three cryptic phylogenetic species that occur sympatrically in Alaska rather than as allopatric groups. The results point to a Siberian–Beringian origin with fragmentation, speciation and subsequent range expansions across Eurasia and North America, while ancestral pileus and wart colour polymorphisms persisted and Beringian populations adapted to climatic cooling.
