The latex color change

ranges from very fast to very slow and long-time-taking.
L. deterrimus milk does not change to green, old fruitbodies do get green as do L. semisanguifluus and sanguifluus. L. salmonicolor never turns green in age. The milk (latex) of deterrimus stays orange or very very slowly getting darker, semisanguifluus getting purple after some time, sanguifluus immediately. L. hemicyaneus and quieticolor change about the same pace as deterrimus but differ in other fruitbody colors and the bluish beneath the cuticle. There are others in Europe but very rare. I guess in North America there must be even more but I never had the chance to meet some of the redders when across the ocean.
Oh yes and L. salmonicolor of course also “milks” reddish-purple relatively fast.
Intensity of all these changes may vary but never they are lacking.

well, yeah, but…

Yeah, but, all the time I saw something that was understanding of L. salmonicolor, the gills stained a characteristic dark purple from the orange latex. Different from say, L. deterrimus which stained a forest green from the orange latex, or L. deliciosus which doesn’t stain. But this staining of the gills was slow(ish), usually you could see some point on the gills with some spots of the staining color.

But as always, I try to understand the separations of the orange latex Lactarius, and when I do, I seem to not get anywhere in any amount of detail… so, again I’ll give up for now and crawl back under my rock still not knowing what to say…

Yes, without a doubt

this is fir.
It is salmonicolor.

Habitat photo added & a link to L. salmonicolor photos

I added a photo of the habitat where these mushrooms were collected showing a very mixed forest, but with a tree branch in the lower left corner that looks more like fir. I also found a website by Bart Buyck, curator of the Mycology Herbarium of the National History Museum in Paris, which shows photos of mushrooms identified as Lactarius salmonicolor that appear the same to me as the mushrooms in this observation at the following link -

Do you have other photos? A cut through the cap would be helpful. How was the color change under the cuticle? There could be L. quieticolor or L. hemicyaneus but the color seem to bright for me. Or just deliciosus? Were there pines nearby?

Well, it just seems that L. salmonicolor might be a stretch here? The photos don’t show the staining reactions, and the habitat isn’t common with other obs. here. Maybe other orange-latex species should be looked at?

I think

he means under fir but also in woods where spruce or beech is present too.
I have never found it anywhere else but with fir and in very frequent cases there were also spruces and beeches there.
It suffices if there is a young or younger fir somewhere nearby.

Pierluigi Angeli,the Italian mycologist who identified this mushroom, says on his website at the link below (English translation)-

Lactarius salmonicolor “Habitat: it grows – mainly under fir, also mixed to beech or spruce.”

L. salmonicolor

grows with fir exclusively.

Found with Spruce

I believe they were with the spruce trees, but I didn’t find all of them so I’m not positive.

Don’t show…

These don’t seem to show the usually staining reactions for L. salmonicolor. What tree was associated with these?
