Several species of Gyromitra are highly poisonous when consumed raw the presence of gyromitrin. In this study, Gyromitra specimens deposited in the Korea National Arboretum were re-examined and subjected to molecular sequence analysis. G. gigas, G. aff. perlata, and G. tianshanensis were identified based on their morphological features and molecular phylogenetic analysis for the first time in Korea. Furthermore, internal transcribed spacer and 28S rRNA sequences of G. esculenta and G. infula were analyzed to confirm their phylogeny.

We have discovered Vicia grandiflora Scop., a newly invasive alien species in Baekun-ri, Okcheon-gun, Chungcheongbuk-do, Korea. This species is native to regions from Central and Southeast Europe to Central Asia and Iran and is reported as an invasive species in North America and Japan. This species is similar to the Vicia sativa complex (V. sativa subsp. sativa, V. sativa subsp. nigra) but can be readily distinguished by the undivided ovate to semi-hastate stipules of the upper leaves, yellowish petals, large size of its flower, and elongated hilum. In the field, V. grandiflora grows in disturbed sites near cultivated land, suggesting that their seeds are typically transported by vehicles along with fertilizer or livestock feed. Here, we present the morphological description, photographs, and sites of V. grandiflora growth, which will be useful in guiding the management of this invasive alien plant.

The complete chloroplast genome (cp genome) sequence of Clematis calcicola J. S. Kim (Ranunculaceae) is 159,655 bp in length. It consists of large (79,451 bp) and small (18,126 bp) single-copy regions and a pair of identical inverted repeats (31,039 bp). The genome contains 92 protein-coding genes, 36 transfer RNA genes, eight ribosomal RNA genes, and two pseudogenes. A phylogenetic analysis based on the cp genome of 19 taxa showed high similarity between our cp genome and data published for C. calcicola, which is recognized as a species endemic to the Korean Peninsula. The complete cp genome sequence of C. calcicola reported here provides important information for future phylogenetic and evolutionary studies of Ranunculaceae.

As part of a study to understand the current status of Korean plant species propagated in foreign countries, we conducted extensive surveys on Korean living collections in the Arnold Arboretum of Harvard University, the oldest public arboretum in North America. Specifically, we collected and identified the voucher specimens of the living collections and further examined the collection databases to understand the history of how Korean plants were introduced to the Arboretum. We found that a total of 154 Korean taxa (belonging to 49 families and 81 genera) have been planted in the arboretum. Most plants originated from seeds that were directly collected in Korea or obtained via seed exchanges with botanical gardens in Asia, Europe, and U.S.A. Of the 154 taxa, 16 are Korean endemic species, and three are listed as endangered species. In addition, 62 taxa are as floristic regional indicator species of Korea used by the Ministry of Environment.

Two unrecognized species of Sparganium of Korea were found during the our field expeditions and phylogenetic analyses of specimens deposited in the Herbarium of Korea National Arboretum (KH). S. coreanum H. $L{\acute{e}}v$. was first reported as a new species based on the specimen (Taquet, 2150) collected from Jeju Island. It has been recognized as synonym or infraspecific taxa of S. stoloniferum and S. eurycarpum or even never recognized recently. However, phylogenetic tree showed that S. coreanum is monophyletic and has sister relationship with S. eurycarpum. Furthermore, additional distribution localities were also found by herbarium survey. Morphological characteristics and distribution information of S. coreanum will be discussed. Another Sparganium species found from Mt. Daeam is occurring either as floating or emergent. Although we could not identify this species since lack of any flowers or fruits for two year surveys, phylogenetic analyses results showed that this species belong to the clade of S. glomeratum, which is distributed in high elevation lakes and marshes of Europe, Asia, and North America. Additional survey of morphology and report will be needed.

During the 2014 survey of the mushroom flora of Gwangneung forest in South Korea, we collected two specimens of boletoid mushroom growing on a felled tree of Pinus koraiensis. These specimens were characterized by a light brown to reddish-brown pileus with appressed tomentum, pore surface bluing instantly when bruised, golden-yellow mycelium at the base of stipe, and lignicolous habitat. Both specimens were identified as Buchwaldoboletus lignicola, a rare basidiomycete, based on morphological characteristics and sequences of internal transcribed spacer (ITS; fungal barcode). Here, we describe these specimens and provide the first report of this genus in South Korea.

To improve our understanding of the relationship between soil higher fungi (belonging to Ascomycota and Basidiomycota) and Abies koreana, we surveyed A. koreana soil fungal communities in a forest in Mt. Halla, Jeju Island, Korea by next-generation sequencing (Illumina Miseq). To confirm the soil higher fungal communities, we collected two types of soils from a defined plot: soils with dead (AKDTs) and living A. koreana (AKLTs), respectively. Soil fungi were classified into 2 phyla, 19 classes, 64 orders, 133 families, 195 genera, and 229 OTUs (895,705 sequence reads). Nonmetric multidimensional scaling (NMDS) showed significantly different soil higher fungal communities between AKDTs and AKLTs (p < .05). In addition, the saprophyte composition was significantly affected by A. koreana status (p < .05). The proportion of the mycorrhizal Clavulina spp. was different between soils with AKDTs and AKLTs, suggesting that Clavulina spp. may be a crucial soil fungal species influencing A. koreana. This study will lead to a better understanding of the ecological status of A. koreana in Mt. Halla. In addition, this study could be useful for the conservation and management of A. koreana habitats.

Gnaphalium L. is a small herbaceous genus comprising up to 80 species in worldwide (Asia, North to South America, Africa, and Oceania). This genus is highly polymorphic which embrace uncommon broad morphological boundary, and thus further studies were needed to proper taxonomic delimitations for the genus and its relatives. Gnaphalium uliginosum L. was usually found in moist sites such as margins of lake, pond, reservoir, stream banks and paddy field. This squat plant is solely known species in Korean Gnaphalium. During the revisionary study of the tribe Gnaphalieae (Asteraceae) in Korea, however, we found several materials in domestic herbaria (e.g., SNU, KWNU) that identified as G. uliginosum or Gamochaeta pensylvanica (Willd.) Cabrera collected from central to northern Korea, but clearly differ to the morphology of G. uliginosum. The external morphology of the materials is seemingly the only feature at odds with G. uliginosum. However, its morphological characters such as tall erected stems (ca. 30cm), hairs on seeds and whitish tomentose hairs on the whole plants are easily distinguished from G. uliginosum, and rather it looks like G. tranzschelii Kirp. Although the name G. tranzschelii have been treated as synonym of G. uliginosum by several authors, its distinct morphology might be sufficient to separate to two independent taxa. Generally, the morphological polymorphisms and hybridization of G. uliginosum complicate the taxonomy of the species, and thus further investigation for their habitat, distribution and morphology were needed to their taxonomic entity.

Vulpia octoflora (Walter) Rydb.가 경기도 여주시 강천리 일대에서 발견되었다. 본 종은 북아메리카 원산으로 알려져 있으며, 최근 호주와 일본, 우크라이나에서 침입외래식물로 보고된 바 있다. V. octoflora는 주로 건조한 건조한 모래나 자갈 모래밭에 자라는 잡초성 식물로, 도로변을 따라 개방된 지역이나 인위적 교란 지역에서 빈번하게 발견된다. 학자에 따라 북아메리카 지역에 분포하는 개체들의 지리적 분포와 형태 변이를 근거로 종하분류군으로 세분화하기도 하지만, 형태 변이의 일관성 부족으로 인해 종내 변이로 인식하여 통합하여 처리하는 것이 타당하게 여겨진다. 본 종은 최근에 국내에 보고된 침입외래식물인 들묵새아재비와 유사하나, 소수당 달리는 소화의 수가 더 많고, 호영 정단부의 까락의 길이가 짧은 것으로 명확히 구분된다. 좀들묵새에 대한 생태계 위해성 연구는 진행된 바 없으나, 최초 발견지인 여주시 강천섬 일대는 멸종위기 2등급종인 단양쑥부쟁이의 자생지이기 때문에, 새롭게 유입된 외래식물의 잠재적 생태 교란에 따른 위해성 평가 및 확산 방지를 위한 모니터링이 필요할 것으로 여겨진다. 본 연구에서는 주요 형질에 대한 기재와, 지리적 분포, 도해도, 화상자료와 국내에 분포하는 동속 분류군과의 검색표를 제공하고자 한다.
