Amanita subgenus Lepidella is a well-known group that includes lethal amanitas. However, the taxonomic investigation of Korean Amanita species is still in progress. In this study, we collected Amanita specimens in Korea from 2009 to 2015 and classified 22 of them as subgenus Lepidella based on the morphology. Phylogenetic analysis of the 22 Amanita specimens based on the internal transcribed spacers sequences identified 16 phylogenetic species which included three undescribed Amanita species (A. sepiacea, A. modesta and A. kotohiraensis). Microscopic features of newly recorded Amanita species were photographed and line drawings were made. All collections cited here are deposited in the Herbarium Conservation Center of the National Institute of Agricultural Sciences.

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.
