Hello again. I found a few examples of this beautiful Lactarius with a burnt orange pileus and a reddish stipe which gradually deepens to blackish-red at the base. Spores subglobose with reticular ornamentation around 8 um diameter. Sap not abundant turbid (not milk-white) slightly bitter but not strongly so. I was thinking that this is the Lactarius atlanticus but after reading this site:
two look likes are mentioned: L. serifluus and L. subumbonatus, but I think both are not the same that I have photographed. The atlanticus epithet (hence indicating its distribution is far west) and the dark red stipe put some doubt in my mind... BUT I think I should not look elsewhere and confirm this as L. atlanticus!
