Diplomitoporus is a genus of fungi in the family Polyporaceae. The Dictionary of the Fungi (10th edition, 2008) estimated the widespread genus to contain 11 species; since then, the genus has grown with the additional of several newly described species, and some transfers from other genera. Diplomitoporus has been described as a wastebasket taxon, containing "species that share common macroscopic and microscopic characteristics, but are not necessarily related."
Diplomitoporus was circumscribed in 1970 by Polish mycologist Stanislaw Domanski, with Diplomitoporus flavescens as the type species. This species was originally described as a member of Trametes by Giacomo Bresadola in 1903.
