Molecular research confirms the relations of Gyrodon, with the decurrent-pored mushroom G. lividus, Paragyrodon, with the type species P. sphaerosporus, and Paxillus as sister groups, together lying near the base of a phylogenetic tree from which the genus Boletus arises.
Molecular research supports that Gyrodon is related to the decurrent-pored mushroom G. lividus, Paragyrodon to the type species P. sphaerosporus, and Paxillus as sister groups; these are positioned near the base of a phylogenetic tree from which the genus Boletus emerges.
