As per Nguyen et al., Mycologia October 2016: 16-106 Phylogenetic assessment of global Suillus ITS sequences supports morphologically defined species and reveals synonymous and undescribed taxa:

“Summarizing our results, we consider: (i) S. neoalbidipes M.E. Palm & E.L. Stewart a synonym of S. glandulosipes Thiers & A.H. Sm.; (ii) S. borealis A.H. Sm. Thiers & O.K. Miller is a synonym of S. brunnescens A.H. Sm. & Thiers; (iii) Boletus serotinus Frost and Boletus solidipes Peck synonyms of Suillus elbensis (Peck) Kuntze; (iv) S. lactifluus (With.) A.H. Sm. & Thiers a synonym of S. granulatus (L.) Roussel; and (v) S. himalayensis B. Verma & M.S. Reddy a synonym of S. americanus (Peck) Snell. Further, we propose usage of the names: (xi) S. clintonianus in the place of the North American S. grevillei; (xii) S. ampliporus in the place of the North American S. cavipes; (xiii) S. elbensis in place of the North American S. viscidus; and (xiv) S. weaverae in place of the North American S. granulatus."
