Reassessment of the generic limits for Hydnellum and Sarcodon (Thelephorales, Basidiomycota)
DNA sequences from the nuclear LSU and ITS regions were used for phylogenetic analyses of Thelephorales with a focus on the stipitate hydnoid genera Hydnellum and Sarcodon. Analyses showed that Hydnellum and Sarcodon are distinct genera but that the current division, based on basid...
