Milk white or gray.

The milk doesn’t turn grey but dries greyish (on the gills). According to Heilmann-Clausen pale olivaceous grey. For the three major Lactarius experts (Heilmann-Clausen, Basso and Bart Buyck) is L. fluens an independent species.

Let’s go for L. blennius as you propose. I have not enough experience to determine the specie correctly myself.

For me it looks like Lactarius blennius, in Germany very common in the beech wood. Look at this link http://www.funghiitaliani.it/index.php?showtopic=15951. L. blennius var. fluens (L. fluens) is very similar but has normaly a paler margin.

But keep in mind,

that in L. fluens the milk also is staining and not staying white.

Milk is almost waterly/white. Seems to fit L. fluens.

M.O. usually consults IndexFungorum or MycoBank. Just look what is valid now.
But if milk really is staying white I do not know which species this is. With beech you also have Lactarius pallidus but your observation lacks any reddish-pinkish hues which are always in some way present in pallidus.
Have there been fir trees nearby? L. albocarneus, but here context is turning yellowish.

Taxonomy

I am unsure of taxonomy for fluens. Wikipedia says this:

“…
Lactarius fluens is another species that has been included in L. blennius; originally described in 1899 by Jean Louis Émile Boudier, in 1999, German Joseph Krieglsteiner suggested that it is actually a variety of L. blennius, naming it Lactarius blennius var. fluens..”

MO doesn’t have a name for either fluens or blennius var fluens. What gives ?

Latex

Latex is and stays white, even after 1 hour. Also on handkerchief.
It is also abundqnt, but I do not have enough experience to determine whether it is extremely abundant, very abundant, abundant or almost abundant :)

Then there are just those two options of

Lactarius blennius (incl. fo. viridis) and Lactarius fluens.
Maybe it is fluens, on the second photo it seems like the milk is drying brownish.

Beech

Clearly associated to beech

Similar

would be L. vietus, but also milk is drying greyish.
L. utilis/fascinans but also latex is not drying white.
Search in this group.
Are there conifers or just beech and birch?

Latex
By: deuteragenie
2012-07-15 11:51:42 PDT (-0700)

Latex dries white, not grey. This would seem to rule out L. blennius.

Lactarius fluens

Could be lactarius fluens, but name does not exist in MO.
