We isolated endophytic fungi from the leaves of woody plants inhabiting the Ulleungdo Island and Yeosu in South Korea. The fungal strains were identified based on their morphological characteristics in conjunction with phylogenetic analysis, which was performed using sequences of the internal transcribed spacer, large subunit rDNA, and β-tubulin DNA. We confirmed the presence of Neofusicoccum mangiferae and Thyronectria cucurbitula, two endophytic fungal species that had not been previously recorded in Korea. In this report, we describe the morphological characteristics of these fungal strains and results of the DNA-based phylogenetic analysis.

The three wild populations including unrecorded two wild populations and Do-dong population, where designated as a Natural Monument NO 51, of Cotoneaster wilsonii in Ulnung Island were studied. The population at Yilmoldae, western coast of the island is in the threat by the visitors, while the population at Tonggumi is well conserved due to the geomorphologically difficult to access . The existing 25 to 50 maturing individuals are are potentially vital sources fer the island species recovery projects in the future. There are no statistical difference in the floral characteristics of the species such as both length and width of the petals, while statistical difference were shown from the leaf characteristics such as length, width and area of the leaves in the three studies areas.

Macrofungi play important roles in forest ecology as wood decayers, symbionts, and pathogens of living trees. For the effective forest management, it is imperative to have a comprehensive overview of macrofungi diversity in specific areas. As a part of the National Institute of Biological Resources projects for discovering indigenous fungi in Korea, we collected macrofungi in Gayasan National Park from 2017 to 2018. These specimens were identified based on morphological characteristics and sequence analysis of internal transcribed spacer (ITS) or the nuclear large subunit rRNA (LSU) region. We discovered 17 macrofungi new to Korea: Butyrea japonica, Ceriporia nanlingensis, Coltricia weii, Coltriciella subglobosa, Crepidotus crocophyllus, Cylindrobasidium laeve, Fulvoderma scaurum, Laetiporus cremeiporus, Lentinellus castoreus, Leucogyrophana mollusca, Marasmius insolitus, Nidularia deformis, Phaeophlebiopsis peniophoroides, Phanerochaete angustocystidiata, Phlebiopsis pilatii, Postia coeruleivirens, and Tengioboletus fujianensis. We described their detailed morphological characteristics.

An unrecorded species, Carex benkei T. Shimizu, was found in Is. Jaewondo, Jaewon-ri, Imja-myeon, Sinan-gun, Jeollanam-do and Dongbaik-dongsan, Seonheul-ri, Jocheon-eup, Jeju-si, Is. Jeju-do, South Korea. C. benkei is closely related to C. transversa Boott and C. brownii Tuck., and C. benkei is distingushied from the pistillate scales length, excluding the awn, similar to the achene and the beak of the achene with an annular appendage. A new Korean name, 'Gin-Hwa-Sal-Sa-Cho', was given based on its long pistillate scales excluding the awn compared with Carex transversa Boott. We provide here its redescription, illustrations, photographs, and a key to species of the sect. Confertiflorae Franch. ex Ohwi.

Plagiothecium platyphyllum Mönk (Plagiotheciaceae), a species unrecorded previously in the moss flora of the Republic of Korea (South Korea), was collected in the Surak stream of Mt. Daedun in Jeollabuk-do Wanju-gun Sanbuk-ri. This species was known to be distributed around China, Japan, North Korea, and Europe. The morphological characters of P. platyphyllum's leaf are ovate-lanceolate, and mostly asymmetric, 2.0~2.5 × 1.0~1.4 mm. The margin of the leaf is entirely below and weakly serrulated near the apex. The costae parts are double, unequal, with one branch reaching to the mid-leaf. Median leaf cells are linear-rhomboidal, 80~127 × 10~16 ㎛ and alar cells are rectangular. Central strand is developed in the core of the stem.

Echinochloa oryzoides (Ard.) Fritsch is one of major troublesome weeds in the paddy fields in Korea. The Korean name and scientific name of the species has been controversial among researchers. The Korean names 'Nonpee' and 'Gangpee' are being used interchangeably and the application of its scientific name is being confused. The committee composed of the Korea National Arboretum and the Korean Society of Plant Taxonomists has agreed in the use of 'Nonpee' as the Korean name. Therefore, we suggest to use the agreed name of the species for researchers to avoid confusion. In addition, the application of scientific names is also confused with E. oryzoides (Ard.) Fritsch and E. oryzicola (Vasinger) Vasinger. E. oryzicola (Vasinger) Vasinger should be applied to the known 'Nonpee' and E. oryzoides (Ard.) Fritsch should be applied to the unrecorded 'Nadononpee' discovered in Masan, Gyeongsangnam-do.

Pratylenchus loosi Loof, 1960 is recorded for the first time from Korea. The nematode was isolated from the roots of tea (Thea sinensis L.) and soil around the roots from Yeongam-gun, Jeo-llanam-do and Namjeju-gun, Jeju-do, Korea. This species has two lip annuli. The female is 433-646 $\mu\textrm{m}$ long: a＝ 29.1-37.5, b ＝ 5.1-6.4, c ＝ 15.0-21.3, vulva(%) ＝ 73.0-85.4. The male body length is 408-512$\mu\textrm{m}$ long: a＝36.1-40.0, b＝4.8-6.7, c ＝17.0-19.0, and spicule ＝ 14.1-18.0 $\mu\textrm{m}$. The stylet is 11.6-18.0 $\mu\textrm{m}$ long and the number of incisures is four. The shape of spermatheca filled with sperm is broadly rounded, oval and quadrangular The shape of tail is narrowly round to subacute.

We collected leaves of Pinus koraiensis and Thuja koraiensis and roots of Bletilla striata from various sites in Korea. The leaf and root samples were surface-sterilized and endophytic fungi were isolated. Fungal isolates were identified based on their morphological characteristics and a phylogenetic analysis of internal transcribed spacer regions, large subunit regions, and the ${\beta}$-tubulin gene. Consequently, we identified five species of endophytic fungi, namely Colletotrichum simmondsii, Fusarium sterilihyphosum, Diatrypella pulvinata, Ochroconis globalis, and Sphaeria chrysosperma. These species have not been previously reported in Korea and we report them here with descriptions and illustrations.

Two naturalized species, Chaerophyllum tainturieri Hook. (Umbelliferae) and Barbarea verna (Mill.) Asch. (Cruciferae) were newly reported from South Korea. C. tainturieri., 'Jeon-Ho-A-Jae-Bi', was found at World Cup park in Sangam-dong, Mapo-gu, in Seoul, and the genus Chaerophyllum is reported for the first time from South Korea in the present paper. It is distinguished from the genus Sphallerocarpus by having cylindrical fruit, and each furrow with one vitta. B. verna, 'Bom-Na-Do-Naeng-I', was found on a riverside area of Suyeong River, Geumsa-dong, in Busan. It can be distinguished from B. orthoceras by silique 4-8 mm long , seeds 1-2 mm long, and basal rosette leaves with a 4-11 large pairs of lateral lobes.

An unrecorded species, Carex aequialta K$\ddot{u}$k. (Cyperaceae), was found in Yecheon-gun, Gyeongsangbuk-do and Jeju-si, Jeju-do. This species is distinguished from related taxa, C. maximowiczii Miq., C. suifunensis Kom., C. phacota Spreng., C. dimorpholepis Steud., C. shimidzensis Franch. and C. tegulata H. Lev. & Vaniot, by having suberect lateral spikes, awnless pistillate scales, short rhizomes and corymblike inflorescences. This taxon was named 'Mul-kko-ri-sa-cho' in Korean based on its external appearances and habitat. We provide its description, illustrations, photographs and the key of related taxa in Korea.
