As part of the mushroom surveys in the unexplored areas of Korea in 2019 and 2020, a phalloid fungus was found in a saline sand beach. The specimen was mainly characterized by its reticulate pileus and violet volva with well-developed rhizomorphs. Based on ribosomal DNA internal transcribed spacer (ITS) sequencing and morphological characteristics, the specimen was identified as Phallus hadriani. Additionally, a morphological comparison of closely related species was performed. This study describes for the first time the presence of P. hadriani in Korea.

Vulpia octoflora (Walter) Rydb., a newly identified invasive alien species, was found in Gangcheon-ri, Yeoju-si, Gyeonggi-do, South Korea. It is native to North America and has been reported to be an invasive alien plant in Japan, Australia, and Ukraine. Vulpia octoflora is a weed that grows mainly in dry sandy or rocky soil and is frequently found along the roadside in open areas or in artificially disturbed sites. This species is similar to the recently confirmed alert alien species, V. bromoides (L.) Gray, but is readily distinguishable due to more florets per spikelet and a short awn of the lemma. A detailed species description, the geographical distribution, illustrations, photographs, and an identification key for all species of Vulpia that occur in Korea are provided.

The current status of geographical distribution range of Deutzia paniculata, one of the korean endemic plants, was investigated based on the species distribution information. The information of the geographical range used for analysis includes all the published references to the distribution of D. paniculata, herbarium specimens in Korea National Arboretum (KH) including its online database: http://www.nature.go.kr, and field research. Although, D. paniculata was firstly recorded in Wonsan, Hamgyeongnam-do, North Korea, this research revelaved that D. paniculata is mainly distributed in Gyeongsangbuk-do and Gyeongsangnam-do, southern regions of the Korean Peninsula. According to the distribution map, this species was estimated on distribution edge of in Anyang region of Gyeonggi-do, Mt. Naejang of Jeollabuk-do and Mt. Taebaek of Gwangwon-do on the distribution edge. However, it was made use of intensive field survey to identify the natural population of the species in these regions. D. paniculata habitat was mainly distributed between 290 meters and 491 meters in altitude, but it was also found ranged from 936 to 959 meters in Gun-wi, Gyeongsangbuk-do, South Korea. The distribution slope was 5° to 35° and the north, N, NE and NW in the aspect. The flora of vascular plants in D. paniculata habitats was listed in 137 taxa: 54 families, 103 genera, 120 species, 2 subspecies, 12 varieties and 3 forms while Korean endemic plants were found in three taxa, Stewartia koreana, Weigela subsessilis and D. Paniculata. Based on a collection of non-biological environment and biological environment data, D. paniculata population were discussed to make strategy and basic research methods for sustainable preservation.

나고야의정서 발효에 따라 이에 대한 대응이 전세계적인 이슈가 되면서 각 국가들은 자국내 유용자원식물의 주권확립을 위한 움직임을 보이고 있으며 이들의 기원종 확립과 진위 감별을 위한 연구가 활발히 진행되고 있다. 이에 본 연구에서는 전라도 지역 내 생약 자원식물의 분포현황 및 실체를 파악하고자 하였다. 조사시기는 2018년 3월부터 2020년 5월까지 계절별로 해안가, 산지, 농경지 등 다양한 서식환경에 대하여 조사를 실시하였다. 전라도 내에서 확인되 생약자원식물은 106과 243속 405종 31변종 4품종 총 440분류군이 분포하는 것으로 조사되었으며, 한반도 관속식물 4,499분류군(Korea National Arboretum, 2018; Http://www.nature.go.kr/kpni/)의 9.8%에 해당된다. 본 조사지역 내에서 확인된 생약자원 식물 중, 특산식물로는 매미꽃, 할미밀망, 노랑붓꽃 등 11분류군이 확인되었으며, 희귀식물로는 CR등급의 노랑붓꽃을 포함하여, VU등급의 약난초, 흑삼릉 등 25분류군이 확인되었다. 특히 본 조사를 통해 수집된 생약자원식물의 표본, 화상자료, 종자, 생약부위 등은 추후 우리나라의 생약자원에 대한 관리DB를 구축하는데 기초자료로서 유용하게 활용될 것이다.

We report a technique for obtaining seeds of 'Cheongnarae' (a variety of Hosta minor cultivated at the Korea National Arboretum in 2019) by artificial crossing of H. minor, collected from Jeju Island, as the female parent and H. minor 'Krossa Regal', cultivated outside Korea, as the male parent. Among the individuals obtained after sowing, those that showed different morphological characteristics, such as leaf shape and color, were selected. Among these individuals, those with thick leaves and light-colored flowers were further selected. Vegetative propagation and cultivation steps were repeated for evaluation of the characteristics. 'Cheongnarae' has relatively thicker leaves and a darker color (RHS 137A) than the control variety 'Black Hills' and has wings at the point where the petiole meets the leaf blade. The shape of the leaf blade edge is clearly sinuous, and the flower color is close to white (White N155B). 'Cheongnarae' cultivated in this way can be used for pot plant or gardening.

Amanita Pers. is a well-known monophyletic mushroom genus with a broad distribution. However, the diversity of Korean Amanita species has been underestimated, and most taxonomic studies conducted in Korea have only investigated their morphological characteristics. This approach is frequently insufficient for correct identification in fungal classification; therefore, we constructed a phylogeny of Amanita subgen. Lepidella in order to understand the phylogenetic placements of 16 Amanita specimens collected in Korea in 2012. The phylogeny constructed using the sequence data of the internal transcribed spacers and the partial large subunit of ribosomal RNA identified nine Amanita species (A. citrina, A. excelsa var. spissa, A. flavipes, A. fritillaria, A. oberwinklerana, A. pallidorosea, A. rubescens, A. subjunquillea, and A. volvata); of these, A. fritillaria, A. oberwinklerana, and A. pallidorosea are new to Korea.
