Daecheongdo and Socheongdo Islands are located in the West Sea of Korea, 210 km away from land, and are military border areas very close to North Korea, making them difficult to access. Although the ecosystem of the islands is relatively well preserved due to the lack of accessibility, research on fungi of the regions is insufficient. Therefore, we aimed to investigate indigenous fungi in these geographically and geopolitically constrained regions. A survey of the indigenous fungal diversity of the islands was conducted in 2018. All specimens were identified at the species level based on morphological and molecular analyses. Among them, six macrofungi-namely, Agaricus menieri, Crepidotus praecipuus, Dichomitus squalens, Hortiboletus amygdalinus, Melanoleuca friesii, and Trametes lactinea-were not previously reported in Korea. Considering that the proportion of unrecorded species is high in the survey area and period as well as the number of samples collected, similar research on adjacent islands may be necessary.

In the course of the survey of indigenous species, a red algal Hypnea species was collected from eastern coast of Korea. This species is distinct from other species of Hypnea in having percurrent and cylindrical axis, linear to lanceolate branchlets in axes except their lower portion and medullary cell walls without lenticular thickenings. This Korean entity is identified as Hypnea chordacea K$\ddot{u}$tzing (Gigartinales, Rhodophyta) based on those features. This is the first record of Hypnea chordacea in Korea.

Indigenous fungi from Mount Sohwangbyeongsan, Odaesan National Park, Pyeongchanggun, Gangwon-do, South Korea, were investigated between 2013 and 2016. Our survey identified a total of 137 macrofungi species. These species were systematically categorized into 2 phyla, 4 classes, 15 orders, 41 families, and 73 genera. We identified collected specimens to the species level based on their morphology and rDNA sequences. Two species-Lentinellus flabelliformis and Tricholoma stans were newly recorded as macromycota in Korea.

From December 1995 to July 1997, a total of 546 Korean indigenous goats were examined for the presence of internal parasites by parenchymal organs and fecal examinations. Four hundreds seventy eight(87.5%) of the goats were infected with 4 classes and 12 parasitic species. The nematodes were Haemonchus contortus(57.5%), Oesophagostomun venulosum (52.6%), Strongyloides papillosus(48.4%), Ostertagia sp(28.4%), Trichostrongylus colubriformis(17.0%), and Trichuris ovis(13.2%). The trematodes were Paramphistomum sp(17.6%), Fasciola hepatica(15.4%), and Eurytrema Pancreaticum (8.8%). The cestode was Moniezia expansa(16.7%), and the protozoa were Eimeria sp(74.9%) and Toxoplasma gondii(8.6%). The incidence of single or mixed infections among 12 parasitic species were one species infection (6.2%), 2 species(11.5%), 3 species(19.6%), 4 species(24.9%), 5 species(17.8%), 6 species(5.9 %), and 7 species(1.6), respectively. The level of infection according to the age was considerably higher under one year(97.2%) than between one and two years(89.7%), and over two years(69.3%) Among 12 parasites, seasonal pattern was remarkably observed. Most paracites were detected at the highest level in the Winter, whereas Strongyloides papillosus and Paramphistomum sp were in the Spring, and Ostertagia sp and Fasciola hepatica were in the Autumn. Infection rates of Anaplasma sp were 8.6% of 210 goats by blood smear method, and 51.0% by complement fixation test.

Four new Korean records of the gammarid (Crustacea, Amphipoda), Grandidierella fasciata Ariyama, 1996; Moolapheonoides acutifalcatus Kobayashi and Ishimaru, 2005; Guernea terelamina Hirayama, 1985; and Gordonodius zelleri (Berge, Vader and Coleman, 1999) were reported from the Korean indigenous species survey project funded by the National Institute of Biological Resources (2014-2015). Each of these species is well accorded with the original description for the species except for some minor morphological differences. The genera Moolapheonoides Barnard, 1974 and Gordonodius Ariyama, 2011 are reported for the first time from Korea.

Most known species in the Strophariaceae are decomposers and grow on various kind of organic matter. Approximately 18 genera and 1,316 species in the Strophariaceae have been reported worldwide. Through an ongoing survey of indigenous fungi in Korea, 29 specimens belonging to the Strophariaceae were collected from 2012 to 2016. These specimens were identified based on morphological characteristics and molecular analysis of internal transcribed spacer sequences. Fifteen taxa were confirmed, with eight species matching those previously recorded. Seven species in five genera were shown to be new records in Korea: Galerina marginata, Gymnopilus crociphyllus, Gymnopilus picreus, Hebeloma birrus, Hebeloma cavipes, Pholiota multicingulata, and Psilocybe thaizapoteca. In this study, we provide detailed morphological descriptions of these species and investigate their evolutionary relationships by constructing phylogenetic trees.

Ulleung Island is a biodiversity hotspot in South Korea. During a survey of indigenous fungal species from Ulleung Island conducted from 2015 to 2016, we discovered 10 unrecorded macrofungi in Korea. These macrofungi were identified to the species level using morphological features and phylogenetic analysis based on the internal transcribed spacer region: Deconica phyllogena, Mycena zephirus, Phaeomarasmius proximans, Phlebia radiata, Pluteus semibulbosus, Postia alni, Resinicium pinicola, Scytinostroma portentosum, Tricholomopsis flammula, and Tyromyces kmetii. We also provide detailed morphological descriptions for these 10 species.

Dadohaehaesang National Park is a well-known habitat for a variety of indigenous animals and plants; however, there are no studies on the diversity of macrofungi. To undertake a basic survey of the macrofungi diversity in an unexploited area, we focused on surveying the macrofungi in Dadohaehaesang National Park, Korea, during 2017 and discovered two unrecorded species belonging to the order Polyporales. The two species were identified as Cinereomyces lindbladii and Steccherinum bourdotii based on a combination of morphological characteristics and sequence analysis of the internal transcribed spacer region. We provide macro- and micro-morphological descriptions for these two unrecorded species in Korea.

Cecidomyiidae (Diptera) consists of six subfamilies, which are divided into three groups according to larval ecological habits (phytophagous, mycophagous, and zoophagous). The five basal subfamilies of Cecidomyiidae consist entirely of mycophagous species, with approximately 1500 species described worldwide and 29 previously known to occur in Korea. In this study, 37 named species (1 Lestremiinae, 29 Micromyinae, 4 Winnertziinae, and 3 Porricondylinae species) are newly reported from South Korea. We excluded Lestremia yasukunii Shinji from the list of Korean mycophagous cecidomyiids as it is a nomen nudum. Therefore, we herein officially recognize 65 species, 30 genera, and four subfamilies for the Korean mycophagous cecidomyiid fauna. We also provide diagnoses and photographs to aid species identification and discussion on the four years of gall midge taxonomic inventory in South Korea.

우리나라를 대표하는 생물종 풍부도를 도출하는 데에는 상대적으로 짧은 생물종 현장 조사 역사와 여러 기관에서 분야별로 수집한 조사 자료가 산재되어 있다는 한계가 있다. 본 연구에서는 환경부 산하기관들이 보유하고 있는 관속식물 조사 데이터를 취합하여 100년 이상의 시계열 데이터세트를 구축하였다. 자료 통합은 종명, 위치, 시간(연도) 등 최소한의 기준을 적용해 데이터 검증 및 보정 과정을 거쳤다. 통합한 식물종 자료에 따르면 국내 식물종에 대한 체계적인 수집은 2000년 이후에 주로 이루어졌으며, 이러한 조사를 통해 발견된 식물종의 수는 최근 수렴하는 경향을 보이고 있었다. 이는 우리나라에서 국가 차원의 생물종 다양성을 도출할 수 있는 조건이 충분히 갖추어지고 있음을 시사한다. Chao 2 방법을 이용하여 예측한 1951년부터 70년간의 토착식물의 종 풍부도는 3,182.6으로 추정되었다. 이 추정치를 얻기 위해서는 최소 7년의 누적 기간이 필요하다. 본 연구의 식물종 풍부도는 향후 우리나라의 종 풍부도 변화를 연구하는데 기준이 될 수 있다. 또한 사용한 종 풍부도 추정 방법과 통합자료는 지자체 수준 등의 지역 생물다양성을 도출하는 데에도 적용할 수 있을 것으로 생각한다.
