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