A molecular phylogenetic analysis of 40 fungal specimens that were collected from the Korean peninsula from 2000 to 2015 and recorded as Amanita virosa was performed using internal transcribed spacer sequence data. Results confirmed that Amanita oberwinklerana (14 specimens), Amanita rimosa (5), Amanita pallidorosea (20), and Amanita virosa (1) belong to section Phalloideae of subgenus Lepidella, and the morphological features of these specimens were re-examined. The former three species with deadly poisonous white mushrooms were not yet recorded in Korea. Because of their morphological similarities with A. virosa, they are frequently overlooked or misidentified in the field. All collections were deposited in the Herbarium Conservation Center of the National Institute of Agricultural Sciences.
