It’s still unclear how many true species that are hidden in the concrescens/scrobiculatum complex.
A neotype of scrobiculatum has been chosen from the area where Fries described it, but several other collections in swedish herbariums that were ID:d as scrobiculatum, have turned out to be a canadian species, Hydnellum cumulatum.
It’s almost impossible to tell them apart macroscopically (some people claim that they can..). You also need an extremely good microscope to see the important spore details. Drawings can be seen in this article:
I have no doubts about this obs being something in the complex that includes scrobiculatum, though.
I am unfamiliar with the trials and tribulations of this ID.
everyone who manages to identify Hydnellum scrobiculatum :-)
