Pseudohydnum is a genus of fungi in the order Auriculariales. Basidiocarps (fruit bodies) are typically bracket-like and gelatinous, with or without a stipe, with a hydnoid (toothed) undersurface. The genus is widely distributed in both the northern and southern hemisphere, with thirteen species currently described and others awaiting description.
The genus, first described by Finnish mycologist Petter Adolf Karsten in 1868, has not yet been classified with certainty into a family. Molecular research, based on cladistic analysis of DNA sequences, has confirmed Pseudohydnum as a natural (monophyletic) taxon.
