Notes: Found several of these growing in loose clusters in dry spruce-pine forest around a squirrel midden. Large, dry; latex white but scanty; stipe very hollow; spore print apparently failed.
Updates: taste bitter (not acrid at all even slowly); spores ~7.2 × 5.9 µm with partial reticulum of ridges almost 1 µm tall.
More updates: the pileipellis an ixotrichodermium (should it bother me that that sentence actually makes sense to me now??) with a lattice of very narrow gelatinized hyphae above a brown context.

was actually my first reflection, slimy when fresh and the same kind of pale, almost smooth and hollow stem, perhaps also greenish/greyish stains on the gill edges(?), but certainly with acrid taste, and the cap colour on this seems too much brown. Somewhere around trivialis sounds like a good area to search, though.
A section of the pileipellis reveals that this should have been viscid (it’s a beautiful example of an ixotrichodermium). (The stipe also shows the same thing.)
I’m trying to make sense of the Smith monograph. Kauffmanii isn’t far off, but it sounds like it is supposed to be darker-colored (the entire subgenus, actually). And I definitely don’t get an acrid taste, even after sucking on it for a minute (although I now see Smith mentions that this sometimes occurs in section Tristes). Also, Smith emphasizes the extreme thickness of the gelatinous layer (up to 2 mm thick?!), while I find it only to be between 50 µm (mounted in water) to 100 µm (in KOH).
I wonder if it could be in the trivialis group, instead?
Thanks for your help, Irene and Douglas.
sounds MUCH better than camphoratus..
I’ve never heard of it before. Citation/Source?
These kinda look like they might be Lactarius kauffmanii, with the white latex, brown cap, non-staining gills (clear of brown spots), and light colored stipe. But I’ve only seen this one rarely.
in Aurora’s Mushrooms Demystified (p. 78). I would expect the cap to be darker brown, and the gills to be at least slightly brown.
