Hi y’all. My student Sean Westmoreland has completed his thesis on Hydnellum systematics, and we have a key to about 25 species in N.A. that is not yet published. We hope to get the key out this year.

Now that you changed the description to “under oaks and pines” it could very well be H. ferrugineum (=H pineticola)

Swiss 2?

I’m interested to hear what Tom recommends. Fungi of Switzerland volume 2 lists 11 species. According to Index Fungorum there are 45 “good” species (meaning no one has reassigned them in Species Fungorum). Of those 35 are listed in Species Fungorum. I’ll make sure they’re all in MO, not that that really helps in understanding the differences, but at least you know how big the field is.

Better Hydnellum sources

Are there better Hydnellum sources out there, all I have really is the section in Mushrooms Demystified, and I’ve never found that satisfying. It has H. peckii when young as white fuzzy with red dots, and everything else is brown with brown teeth, and I find it hard to separate the species.

I meant under oaks and pines. It was a spot with equally distributed white oak and white pine I think.
