Aureoboletus mirabilis was first described by American mycologist William Alphonso Murrill in 1912 as Ceriomyces mirabilis, based on specimens found in Seattle, Washington [REF].
In a 2001 analysis of ribosomal DNA sequences for a number of taxa in the Boletales order, A. mirabilis was found to be most closely related to species such as Boletus edulis, Phylloporus rhodoxanthus, and Tylopilus felleus.
