  • 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.

  • Tofieldia ulleungensis, a new species of the genus Tofieldia from the Nari Basin on Ulleungdo Island, Korea, is described and illustrated. The new species is similar to T. yoshiiana var. koreana in terms of the plant height and in that it has having a long raceme, whitish tepals, and whitish stigma, but can be readily distinguished from the latter by the presence of 1-2 linear cauline leaves, a slightly bent leaf apex, basal leaves which are twice as wide, a shorter pedicel, a revolute style, and crescent-shaped seeds.

  • 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.

  • We conducted five times surveys, in June, September and October in 2012; June and September 2013, to catalog the mushroom flora in Ulleung-gun, Republic of Korea. More than 400 specimens were collected, and 317 of the specimens were successfully sequenced using the ribosomal DNA internal transcribed spacer barcode marker. We also surveyed the morphological characteristics of the sequenced specimens. The specimens were classified into 2 phyla, 7 classes, 21 orders, 59 families, 122 genera, and 221 species, and were deposited in the herbarium of Korea National Arboretum. Among the collected species, 72% were saprophytic, 25% were symbiotic, and 3% were parasitic. The most common order was Agaricales (189 specimens, 132 species), followed by Polyporales (47 specimens, 27 species), Russulales (31 specimens, 22 species), Boletales (10 specimens, 7 species), and so on. Herein, we also reported the first Bovista species in Korea, which was collected from Dokdo, the far-eastern island of Korea.

  • Sparganium coreanum, a barely recognized species in Korea, was rediscovered during a field survey by the authors, who conducted a re-examination of specimens deposited in the Herbarium of the Korea National Arboretum (KH). This species was described initially by H. $L{\acute{e}}veill{\acute{e}}$ from a specimen collected by F. Taquet from Jeju-do (Taquet 2150). Subsequently, however, it was overlooked and unrecognized among South Korean flora. Several populations of S. coreanum were found in the southern part of the Korean Peninsula and on Jeju-do, although it has long been recognized as S. erectum owing to certain vegetative morphological characteristics shared between the two species, such as robust stems, a similar plant height, and globose rhizomes. However, it is distinct from S. erectum by the number of female heads on the lowest inflorescence branch and the size and shape of the fruit. In this study, we provide a detailed description, illustrations, and photographs with a revised taxonomic key for identification of Sparganium species in Korea.

  • 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.

  • Over five thousand higher fungal specimens were collected from 32 forest areas of Chungcheong and Gyeongsang province from 2012 to 2013. We obtained 513 strains and 3,120 ITS sequences. Mushrooms were first identified with macro- and micro-scopic characters, and their identification was confirmed on the basis of ITS sequences. Voucher specimens were designated for each species found in Korea. Construction of DNA barcoding Database is currently underway with sequences of 409 species. During the development of the database, some new species were recognized, along with several Korean new records. When the system has been completed, it will provide essential molecular information for metagenomic and phylogenetic researches for higher fungi.
