Cortinarius traganus genetics

So far, using the ITS region, Cortinarius traganus is the same whether it on the west coast of North America, the east coast or whether it is in Europe. A true variant of C. traganus, C. traganus var. ochraceus, has the same ITS as its purple brothers and sisters. I’ve never come across a C. pyriodorus sequence.

I regard C. pyriodorus as a synonym of C. traganus. The foul smelling look alike C. camphoratus lacks the orange color of the stipe flesh of C. traganus and as Meinhard Moser once told me it smells like an old goat!

Yes, I see. I need to do some more research to see who says what —
whether it is a variety of traganus, or what. With the tendency to use
American names, the name may stick. I can’t see Smith stating anything
about it in my sources. But thank you for bringing it up.

That doesn’t mean its right.

Bessette, Bessette, Fischer Mushrooms of NENA use this name, as does Roody, Mushrooms of WV.

Why such an obscure choice name? C. pyriodorus Kauffman reads very
much like C. traganus. He does not list C. traganus in NA Flora
1932. Have you seen another reference of pyriodorus ever? I’m curious.

the ones I find under hemlock like this one I usually call C. pyriodorus.
the lighter colored stinker ones growing under spruce I usually call C. traganus. I have no idea if this is correct… when I was at the Newfoundland foray a few years back we found traganus everywhere; I’ll post an ob

Looks like Cortinarius traganus to me.
