The taxonomy of Pseudohydnum gelatinosum and related species has been revised using morphological data and a four-gene dataset. The identity of P. gelatinosum and Tremellodon pusillus has been clarified based on newly collected and sequenced material. Several new species from different regions and a significant divergence in TEF1 sequences in P. gelatinosum have been described and discussed.
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.
