Abstract
Study of the genus Gomphidius from recent material from Asia and North America has been carried out using traditional taxonomy combined with molecular systematics. Two new species of Gomphidius (G. borealis and G. pseudoflavipes) are described, one from Eastern Siberia and a second from rarely collected habitats in the Western United States. One taxon has the longest spores reported for the genus and the second species appears to be associated with a Siberian larch.
We wish to thank Ms. Patricia Eckel of the Buffalo Museum of Science for providing Latin diagnoses for the new species. Hope Miller read and corrected the manuscript. Funding for the molecular work was provided by an Aspires Grant to the first and second authors from Virginia Tech.
