The family Boletaceae primarily represents ectomycorrhizal fungi, which play an essential ecological role in forest ecosystems. Although the Boletaceae family has been subject to a relatively global and comprehensive history of work, novel species and genera are continually described. During this investigation in northern China, many specimens of boletoid fungi were collected. Based on the study of their morphology and phylogeny, four new species, <i>Butyriboletus pseudoroseoflavus</i>, <i>Butyriboletus subregius</i>, <i>Tengioboletus subglutinosus</i>, and <i>Suillellus lacrymibasidiatus</i>, are introduced. Morphological evidence and phylogenetic analyses of the single or combined dataset (ITS or 28S, <i>rpb</i>1, <i>rpb</i>2, and <i>tef</i>1) confirmed these to be four new species. The evidence and analyses indicated the new species’ relationships with other species within their genera. Detailed descriptions, color photographs, and line drawings are provided. The species of <i>Butyriboletus</i> in China were compared in detail and the worldwide keys of <i>Tengioboletus</i> and <i>Suillellus</i> were given.
