The fungal genus Suillus Micheli ex S. F. Gray plays important roles in the survival and growth of plant seedlings. Humans have utilized these ectomycorrhizal fungi to enhance the nutrient uptake and defense systems of plants, particularly inthe reforestation of coniferous forests. The genus Suillus is easily distinguishable by its distinctive morphological features, althoughthe morphology of the fruiting body does not facilitate reliable interspecies discrimination. On the basis of micro-morphologicalfeatures and internal transcribed spacer sequence analysis, we found that 51 of 117 Korean Suillus specimens had initially beenmisidentified. The list of the 12 Suillus species previously recorded in Korea was re-evaluated and revised to only eight distinctspecies: S. americanus, S. bovinus, S. granulatus, S. grevillei, S. luteus, S. pictus, S. placidus, and S. viscidus. We providetaxonomical descriptions for six of these species from the sample specimens.
