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.

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.

Kichulchoia brevifasciata belonging to family Cobitidae is an endemic Korean freshwater fish and restricted to very small areas such as Goheung peninsula, and Geogum Island and Geumo Island flowing into the South Sea. As a decrease of its population was further accelerated, a close investigation on the distribution was required. Among a total of 21 sites surveyed, only 5 sites were confirmed in which K. brevifasciata existed. Based on this result, we classified the 5 sites into 3 categories: Being worthy of preserved, being subject to threaten and staying in good condition.

The present study aimed to investigate the local moth fauna and population change during a year on Island Oenarodo (N34$^{\circ}$27'50", E127$^{\circ}$28'06", 74 m a. s. l.), Goheung-gun, Jeonnam. Moth collecting was carried out using a light trap from March to October, 2007. A total of 231 species and 562 individuals in 14 families were identified. Species of Noctuidae were the most abundant with 86 species and 163 individuals, followed by Geometridae (60 species and 147 individuals) and Pyralidae (39 species and 135 individuals), respectively. Monthly changes of moths species richness and abundance were M-shaped with two peaks at late Spring and late Summer. During the study, a geometrid, Menophra senilis, and a pyralid, Endotricha olivacealis were most abundant with 16 individuals. The estimated species richness using Chao 1 identified 646 species, suggesting that we need more extensive and long-term survey for the better understanding of the total moth fauna on the island.

A single specimen of Gymnothorax pseudothyrsoideus (424.0 mm TL) belonging to the family Muraenidae, order Anguilliformes, was collected from Jeju Island, Korea, for the first time. The specimen is characterized by jaws closing completely, canine teeth on jaws, teeth not exposed when mouth is closed, ovoid posterior nostril, and body color ranging from yellowish brown to brownish with small dark spots aggregating to form larger spots that from approximately four irregular rows along the body. A comparison of mitochondrial DNA 16S rRNA sequences indicated that this specimen corresponds well with G. pseudothyrsoideus (K2P distance, d=0.002) but differs from other Gymnothorax species (11.9-13.7%). Therefore, the new Korean name "Geu-mul-nun-gom-chi" is proposed for the species G. pseudothyrsoideus.

Specimens of Umbraulva with greenish iridescent were collected in the subtidal zone of Jeju Island, Korea. To investigate these collections, plastid rbcL and tufA sequencing of six greenish iridescent specimens, including four Umbraulva japonica, were analyzed. Phylogenetic analysis of a concatenated multigene alignment found that the greenish iridescent specimens belonged to a yet undescribed taxon in the genus Umbraulva. We herein propose the name Um. yunseulla sp. nov. for this specimens. Juveniles of Um. yunseulla sp. nov. resemble the generitype Um. japonica in appearance, showing globular to subglobular and funnel-shaped habits, but the blades of this new species are not split longitudinally like those of Um. japonica. Although the multigene phylogenetic tree showed the polyphyletic clade of Umbraulva with respect to the genus Ryuguphycus, Um. yunseulla sp. nov. formed a clade with Um. japonica and Um. amamiensis by weak bootstrap support. These findings, Um. yunseulla sp. nov., highlight the importance of studying the biodiversity of subtidal habitats from Jeju Island, Korea and further emphasize the need for investigations of macroalgae in the mesophotic zone around the Korean peninsula.

We investigated vascular plants of Jindo Island in Jindo-gun, Jeollanam-do, Korea. A total of 22 field trips were carried out over the course of 48 days from May 2012 to October 2014. As a result, 782 taxa belong to 134 families, 437 genera, 704 species, 11 subspecies, 60 varieties and 7 forms were identified. These include the following: 2 taxa (Drosera peltata var. nipponica, Cleisostoma scolopendrifolium) of Endangered Wildlife Class II under the Act on Wildlife Protection and Management Law. 14 taxa of Korean endemic plants, 53 taxa of floristic regional indicator plants in the third to fifth degrees. In all, 73 taxa of naturalized plants were recorded with the naturalization rate of 9.3%.

We investigated vascular plants of Aphaedo Island in Shinan-gun, Jeollanam-do, Korea. By referring to voucher specimens collected over the course of 28 days from May of 2011 to March of 2016, a total of 451 taxa were identified and grouped into 102 families, 294 genera, 413 species, 6 subspecies, 30 varieties, and 2 forms, of which 9 taxa were classified as endangered or rare, including Albizia kalkora, Salomonia oblongifolia, and Centranthera cochinchinensis var. lutea. A total of 59 taxa were identified as regional indicator plants. Six taxa were endemic to Korea, including Hepatica insularis, Indigofera koreana, and Lespedeza maritima. Three taxa (Rumex acetosella, Aster pilosus, and Hypochaeris radicata) among 52 naturalized taxa were ecosystem-disturbing plants as designated by the Ministry of the Environment. The results of preceding floristic research before and after the inauguration of the Aphaedaegyo (bridge) were used to analyze changes in the number of naturalized species on Aphaedo Island.

As a part of the commemorative joint faunal survey for the 30th anniversary of the Korean Society of Systematic Zoology, the molluscan fauna of Jindo Island was investigated based on sample collection from 6 localities from the 6 to the 8 of Jul 2016. A total of 114 molluscan species from 47 families were collected and identified. Among these, 42 species from 11 families are newly reported from Jindo Island and combining the previous records with the present study totals 157 species from 57 families. Distribution of species records indicates that marine biogeography of Jindo Island represent an overlapping zone for marine organisms which dwell in the Yellow sea and the southern sea areas of Korean waters.
