There are some with dark cap and light stipe

Take a look at num. 4138. There I saw a Lactarius with a dark cap and light stipe. This one had white latex, which did not stain the gills, and some told me they thought it might be L. kauffmanii.

There also is Lactarius argillaceifolius var. megacarpus which can have a fairly dark cap and light colored stipe (and if I remem… the latex does stain the gills brown).

Latex, yes

There are visible drops on the gills (from 6 to 8 o’clock). I can’t decide if there is any significant colour change, though.

Russula grisea?

The problem is the stipe(stem). In L. fallax, the stipe should have a dark, velvety appearance. In fact, in all of the dark-capped Lactarius, the stipe should have a dark color, not white. Also, I see no indication of latex, which is so common in Lactarius as to be almost a given. So, looking at the Russulaceae, the Gray Russula comes immediately to mind. See Aurora’s Mushrooms Demystified or Helene M.E. Schalkwijk-Barendsen’s Mushrooms of Northwest North America for more info. It may not be R. grisea, but is likely a close relative in my opinion.
