They do look pretty close to L. peckii.

I have found L. peckii in this general area before, and noted the acrid taste of the flesh. I usually only check the flesh but according to the literature both flesh and latex are extremely acrid.
Some negative points for L. peckii were that these had adnate gill attachments rather than decurrent.
The gill and stipe colors were paler than usually reported.
The stems were solid and I didn’t see a whitish bloom on any of them.
The spores were close in size(these perhaps a little smaller) but didn’t seem quite as reticulated as my L. peckii obs.
Could be an undescribed species?!?.

I overlooked that in your notes. I was thinking maybe Lactarius peckii but that one is very acrid. I wonder if this is an undescribed species?

Walt….taste was mild
