Thus, the morphological and genetic identity of
Phallus ultraduplicatus and P. sibiricus type material
has been demonstrated. According to the principle of
priority stated in the Article 11.4 of the International

necessary to maintain P. sibiricus as the valid name
for the taxon and consider P. ultraduplicatus as a
synonym.
