in the Bessettes Lactarius book. I agree, it looks like a dead ringer for that species. Can go deeper if and when the dessicata arrives…for now, I’m switching rather than fighting!

ok sorry, Just looked at the MDM and my own pictures. I may have mislabeled mine. My caps all seem to be much more green than brown. Maybe the new Bessette book on lactarius has something.

no dessicata in hand…

still in transit from AK. Will the chemicals work on dried material? And are there no other Lactarius sp. that show a purple color? Olivaceoumbrinus supposedly also shows a magenta rxn. w/KOH… what color of purple does turpis show?

I think its turpis… try ammonia, or KOH.. it gives a purple reaction. Ive seen the stipe like that, but not staining of the gills more of a shade than olive.

tempting to call it by the name of something that occurs just across the Bering Strait…

frankly, I have never seen anything like this Lactarius, and
L. olivaceoumbrinus was the closest that I could come using MDM. But what about the green stainng of the gills, and the black scrobiculae on the stipe? Is that a common feature that simply wasn’t mentioned in the descriptions that I could find online of turpis?

Could it be something else entirely? God knows we felt like we were collecting in a whole nuther world up there…

This Lactarius olivaceoumbrinus looks extremely much like Lactarius turpis(aka necator).

toadskin milk cap (check cap detail!)
