Subgenus: Hydnum subgenus Rufescentia
Section: Hydnum sect. Rufescentia
Subsection: Hydnum subsect. Tenuiformia
Group: Hydnum umbilicatum group sensu Niskanen (H. cf. umbilicatum as used in Niskanen et al.)
This name has been misapplied to Hydnum oregonense. The type is from New York; there are are probably 3 other species hiding under this name:
The intraspecific variation (nine substitutions and indel positions, >1.5% between the two most divergent specimens) observed in H. cf. umbilicatum is so large that H. cf umbilicatum probably represents a species complex. The group can tentatively be divided into four taxa that would seem to have a non-overlapping distribution: Eurasia, central Europe, eastern North America, and western North America.
