We collected the ascomata of Tuber species from the rhizosphere of Quercus dentata in Danyang, Korea. We observed the morphological characteristics of ectomycorrhizal roots and ascomata, and identified the species based on the results of the phylogenetic analysis conducted using the DNA sequences of an internal transcribed spacer, a large-subunit rDNA, translation elongation factor 1-α DNA (TEF1), and MAT. Finally, we identified the fungal species as Tuber himalayense B.C. Zhang & Minter, which has not been recorded previously in Korea. We evaluated the morphological characteristics and conducted phylogenetic analysis of the ascoma and mycorrhiza (associated with Q. dentata) of T. himalayense.
