There is a strong resemblance

to R. laurocerasi as described in Lincoff 1981. Particularly, Lincoff describes it as yellowish, not simply brown. Furthermore, in the similar species list the only other close match is described as occurring “in sand, under pines” which doesn’t fit this observation’s habitat.

with laurocerasi:

No sulcate cap margin, not a brown coloured cap, not spotted brown on stem an gills. This one has a strongly greying flesh, which probably is significant for the ID. About the smell, you’re the only witness..

Is there any legitimate reason

for the negative votes on R. laurocerasi? It doesn’t seem there’s any contrary evidence for that id.

Looks dry and brittle

On full size, I can’t see any latex.

I’m not sure

The yellowish spores, the strongly greying flesh, and the red spots/shades on the cap, are features that I usually recognize in a Russula.
I don’t really rule out Lactarius either, but I can’t recall anyone looking like that.

Well, it’s almost certainly one of the two, and from the clade that contains Russula brevipes, R. adusta, Lactarius piperatus, and the like (http://www.mushroomexpert.com/russulaceae.html) — the big funnel-shaped subsection of the Russulaceae.

So you don’t think that’s scanty latex at the bottom of the cut I made in the gills?
