I’d be happy to share

as the opinions tend to R. vesca, I don’t mind to. I tried a spore print and even the tests suggested below but the specimen was too dried to that, so let it be vesca.

Next year, would you help me to fine tune on russulas, Irene?

Russula colours can be very deceiving. This genus is one of the worst to deal with because they vary so much within each species, so don’t put your trust in comparing cap pictures.
I’ll try the coming season to take photos and show how to ID a xerampelina type :-)

Another good criterion…

for separating R. xerampelina from R. vesca is spore print color, yellow for xerampelina and white for vesca; at least the NA manuals list white for vesca.

I think I know vesca. I think it’s one of the several edible russulas that I collect together for eating; mainly pinkish-brown cap with creamy whitish areas. Solid context, closely spaced gills. I find them on open forest floor where pine and spruce are mixed with deciduous trees. The ones seen in this obs (131766) do look like what I would consider calling vesca.

last photos are from 2 specimens seen on 23/2 50m far from this, I can’t make a separate obs, because I don’t have gills picture, but what do you think they are?

For me it’s enough

to make a search on google images of russula xerampelina and vesca, and xerampelina is near the colours of this one. This is almost like this picture http://healing-mushrooms.net/...

Vesca is very different. I found something about vesca smell like you say Irene, but FAINTLY :“ODOR nil to faintly fishy in age” in Trial field key to the species of RUSSULA in the Pacific Northwest. This is the only thing I read about vesca fishy odor.

However, this specimen is young, is small, I think it was born out of season, and smelled strongly cod.

That’s a pity

that they don’t describe it, because vesca does smell like the xerampelina group.

The best xerampelina character is inside the stem. If you look at image 165871, you can see the spongy marrow that is easily compressed if you push a finger into the stem.. If it isn’t, it is most likely vesca. The cap colour in your photo is very typical for vesca (and the white cap margin) too.

I didn’t find anything about

fishy odor in R. vesca, mostly the sites describe it’s smell like mild or fruity.

Those three traits

are also shared by Russula vesca :-)

The mushrooms that I ID as…

R. xerampelina here in eastern North America all share these three traits, fishy odor, brown bruising on the gills, and excellent edibility. To observe the bruising I usually scratch the gills with a knife point.

There are three types I collect, a brighly colored yellowish-orange one that I have found annually in only one spot under spruce on a lawn, a mottled yellowish-green one that favors conifers. And, most interestingly, a purplish-red one that I have found a couple of times on the edge of a hardwood forest (predominantly oak).

Another good character

for the xerampelina group, is the very soft marrow inside the stem.
Russula vesca has the same smell, but a homogenous stem with a firm flesh.

Cod is okay.

This is not the deep red of true xerampelina, it does look more like the others or favrei (which is more brownish). Russula xerampelina and allies is a very difficult group even for Russulists so it is no mistake to just call it xerampelina-group as do the Americans here mostly. But as you please.
Take a look at my finds under R. xerampelina ss. str.

First of all

I don’t know which is the smell of arenques… it smell of dried fish, like cod.

Second, “Cap 5–14 cm across, convex, later flattening and with a depression, colours very varied, often mixed, dull purples, reds, wine-coloured, cinnamon, straw, fawn, brick or dull brown, moderately firm, sometimes hard, soon dry and matt” so the colours match.

Third, “Habitat under broad-leaved trees, especially beech and oak”. It was on a place with oaks, pines and other trees, but on a road side.

First of all,

did it smell like herring?
Second, I cannot see needles/conifers on these pics. R. xerampelina ss.str. is found with conifers.
Besides, the cap color does not match.
If it is something in the xerampelina-group than most probably either R. graveolens or cicatricata.
