Hydnophlebia omnivora is a species of crust fungus in the family Meruliaceae.

It causes white rot in various woody angiosperms, being found in arid regions of the Southern United States, northern Mexico, and Uruguay.

[3] The fungus was first described scientifically in 1925 by American mycologist Cornelius Lott Shear as a species of Hydnum.

[4] Kurt Hjortstam and Leif Ryvarden transferred it to the genus Hydnophlebia in 2009.

[5] Harold Burdsall and Karen Nakasone proposed a transfer to Phanerochaete,[6] a classification endorsed by MycoBank.
