Tatiana, you could be right

I will continue to look at this collection. As far as I know, S. placidus is only found in eastern N. America. However, some studies of whitebark pine habitats in western N. America have found specimens of Suillus that appear similar to S. placidus. I don’t know if work has been done to show whether it’s S. placidus or something else.

another Suillus species, perhaps?

I’m not proposing another name, but your Suillus is very different from my collections of S. sibiricus/S. americanus. These species are more concolorous, i.e. more or less yellow all over, there are distinct red or blackish glandular dots on the stipe, and there are usually some torn whitish veil remnants on pileus edge. Your specimen is rather massive, too. It looks more like pale-stemmed, robust species, such as S. placidus or even S. luteus (although the latter grows with 2-needle pines, at least here).
