Syn.: Hydnum imbricatum L.


When used as a dye, Sarcodon from the same site did not produce any striking colors: see the rib (and the part above it), arm holes and the collar of the vest that Oluna dyed and knitted for me. Adolf

does Oluna take sweater orders?

That’s how its habitat was described before it was known that it included more than one species. Until now they are imbricatus, squamosus, aspratus – but we still don’t know how many more.

Habitat, conifer is OK for Sarcodon imbricatus.

Sarcodon imbricatus can be found in conifer or mixed conifer/hardwood forests.

Beautiful colours in that vest!
Looks better without blue in it :-)

North American Sarcodon needs a closer look

The circumpolar taxa of the genus Sarcodon from the vicinity of S. imbricatus require further study. This was already pointed out by Harrison, K.A. & D.W. Grund (1987): Differences in European and North American stipitate Hydnums. Mycotaxon 28: 427-455. They compared plates in Die terrestrischen Stachelpilze Europas published in 1975 by R.A. Maas Geesteranus. I have not seen the “Stachelpilze”, but the Mycotaxon discussion suggests that there are more problems in the Sarcodon taxonomy that are still waiting for some closer look. Adolf

All right

let the time tell..
There are plenty of european DNA sequences to compare with.
I have only seen one that could be from BC, and that one is closer to imbricatus, but not identical either.

Sarcodon squamosus as a separate species, was first discovered by mushroom dyers. They found that squamosus was the one that gave blue colours, imbricatus didn’t.

The study of North American Sarcodon is so lacking that I have hard time seeing anything outside of the Sarcodon sp. framework. But I haven’t run any phylogenies yet either – something we need to do.

Until then I’ll follow Adolf’s suggestion to act like a Consensus… and suggest Sarcodon. sp.

Here are links to three Sarcodons that look similar:

Sarcodon squamosus vs. Sarcodon imbricatus

Kent Brothers is working on Sarcodon/Hydnum for the Pacific Northwest Key Council. I asked him this question: “Can you have a look at our Mushroom Observer posting of Sarcodon? Any comments?”

Here is his answer:

“A tricky question. The distinction between S. imbricatus & S. squamosus is based on the study by Johannesson et al. reported in Mycological Research 103 (11): 1447-1452 (1999) which is based entirely on specimens from Norway. In the study, S. imbricatus was associated with spruce (specifically Picea abies), and S. squamosus with pine (specifically Pinus sylvestris). As neither of these conifer species occurs natively here, application of the findings of that study to this area is tenuous. Though your specimens are clearly growing in the vicinity of pines, whence the Mushroom Observer reviewer concluded they must be S. squamosus, the photos also show some fir or spruce needles among the moss. (I can’t tell if they have points, but perhaps you know the trees where they were found.)” [Those non-Pinus needles are needles of Douglas-fir, Pseudotsuga menziesii. – AC]

“The authors state that the species could be readily distinguished macroscopically, though not microscopically. Your specimens (nice photos, by the way) appear to have some characteristics of both, but in my view on the whole are closer to the characteristics of S. imbricatus: long brown non-decurrent spines (contrasted to short decurrent spines with a bluish-gray cast), straight to bulbous stem (contrasted to tapering stem), and depressed pileus with central upward-pointing scales (contrasted to non-depressed pileus with rarely upward-pointing scales). That said, I’m not 100% confident they’re S. imbricatus, and wonder if what we have mightn’t be a third as-yet-undescribed species.”

I would recommend the Consensus to rename this observation to “Sarcodon sp.”
