Taxonomy and multigene phylogeny of Pseudohydnum (Auriculariales, Basidiomycota)

Abstract Taxonomy of Pseudohydnum gelatinosum and its sister taxa is revised via morphological data a four-gene dataset (ITS, nc LSU rDNA, TEF1 , RPB1 ). Identity P. Tremellodon pusillus re-established based on newly collected sequenced material from their type localities. alienum Europe; umbrosum temperate East Asia; cystidiatum meridianum placibile Vietnam; omnipavum North America are described as new to science; translucens brunneiceps Asia redescribed. Most collections belong ssp. pusillum . A significant divergence sequences in discussed.
