Key that I can share, no.

But for western NA you can start with Franklin’s thesis on Taxonomic Study Of Hydnellum and Sarcodon for Northern CA. The Hall and Stuntz publications on the Pileate Hydnaceae of the Puget Sound Area and the original descriptions by Harrison.

uh huh.

IF you cut them in half. Flesh color is an VERY important feature.

This could be one of three species, H. regium, a second undescribed species that resembles regium, but is thinner fleshed, smaller and more fiberous in texture, I have collections of it from WA, OR and CA. The pale growing margin and roughened cap are more like H. cyanopodium, but so far it’s known from a small range from far northern CA into central OR. But the growth of yours pictured here is not unlike some of the H. regium I saw last week.

ah yes, the live and learn phenom.

these Hydnellums are a bitch to ID to sp. Got good key?

We also collected more of these very dark Hydnellums (perhaps another sp., tho) at Haystack this year, and gave them to a dyer friend. Share the love. ;)

yep – that was new for me, too. Definitely raised BOTH eyebrows.

From the 2008 Families of Fungi book:
“scrupose: rough with very small hard points.”

eye-catching even when older…

thanks for the description link, Christian. It cleared up one point…the lack here of a rooting stipe (“sometimes bulbous base”, in “non-original” description in MycoBank link).
Plus, a new and ridiculously obscure descriptive word to add to my vocabulary: “scrupose!”

It’s really beautiful when young

I’ve only seen it once – Big Lagoon in Humboldt.

MycoBank’s entry is pretty good:

nice to get a tentative ID on this one…
