英文摘要	Suillus spraguei, synonym S. pictus, has been reported from eastern North America and eastern Asia associated with Pinus subgenus Strobus. Published phylogenetic analyses of rRNA internal transcribed spacer (ITS) sequence and population genetic studies indicated that S. spraguei as currently circumscribed might contain several geographically distinct species. This study examined this possibility through a multigene analysis of S. spraguei specimens from eastern North America and eastern Asia. These specimens were associated with Pinus strobus, P. koraiensis, P. armandii, and P. kwangtungensis. The multigene analysis included three genomic regions: the genes for translation elongation factor 1a (TEF1) and RNA polymerase II largest subunit (RPB1), and the nuc rRNA segments ITS1-5.8S-ITS2 (ITS) and 28S D1-D2 domains (28S). This study confirms that the S. spraguei complex consists of at least three cryptic species: S. spraguei sensu stricto associated with P. strobus in eastern North America; S. phylopictus associated with multiple species in Pinus subgenus Strobus (5-needle pines) throughout China and Japan; and S. kwangtungensis, currently found only in P. kwangtungensis forests in southeastern China. A third new species from Japan and Korea was suggested based on ITS phylogeny. Morphologically, S. spraguei and S. phylopictus resemble each other, whereas S. kwangtungensis is covered with more floccose scales. The new species add to the knowledge of macrofungal diversity in eastern Asia and highlight the necessity of comparing broadly distributed species complexes using morphological, molecular, and ecological data.
