Larvae, pupae, and adults reared from the pupae of Simulium (Boreosimulium) konoi were collected and recorded from Korea for the first time. I provide detailed descriptions of both immatures and adults accompanied with photographs. The subgenus Boreosimulium, previously unknown from Korea, contains 19 species in 3 species-groups worldwide and only 2 species, viz, S. (B.) konoi and S. (B.) tokachiense, are recorded from Japan. Simulium konoi is unique among the members of the subgenus by having water dropshaped denticles on the anterior portion of the cibarium in females, which is considered as an autapomorphic character so far not found in other black flies, W or inverted V-shaped ventral plate of male genitalia, and larval thorax and abdominal segments covered with short black setae. Korean specimens of S. konoi collected from two adjacent localities can readily be recognized by denticles on the cibarium in females and well-developed ventral plate of male genitalia but showed geographical variation, e.g., lacking ventral tubercle on larval abdominal segment IX. Due to the autapomorphy and other characters found in S. konoi, the current placement of the S. konoi in the subgenus Boreosimulium or species-group assignment is tentative.

전라남도 영암과 대구광역시, 대전광역시에 분포하고 있는 미기록 귀화식물 Hedyotis corymbosa (L.) Lam.을 발견, 보고하고자 한다. 본 종은 주로 개울이나 계곡 주변, 또는 밭 가장자리에 햇빛의 양이 충분하면서도 습한 모래가 섞인 땅에서 비교적 큰 군락을 이루고 자란다. 동일한 속 중 유사한 형태를 보이는 백운풀이나 긴두잎갈퀴에 비해 화경이 발달하고, 꽃의 수가 1-7개로 많이 달리는 특징이 있다. 국명은 종소명이 'corymbosa (산방화서의)'이므로 산방백운풀로 신칭하였다.

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.

The genus Peronospora, an obligate biotrophic group belonging to Oomycota, causes serious damage to a variety of wild and ornamental plants, as well as cultivated crops, such as beet, rose, spinach, and tobacco. To investigate the diversity of Peronospora species parasitic to Stellaria and Pseudostellaria (Caryophyllaceae) plants in Korea, we performed a morphological analysis on dried herbarium specimens and molecular phylogenetic inferences based on internal transcribed spacer rDNA and cox2 mitochondrial DNA sequences. As a result, it was confirmed that there are four species of Peronospora parasitic to specific species of Stellaria and Pseudostellaria, all of which were hitherto unrecorded in Korea: P. alsinearum (ex Stellaria media), P. stellariae-aquaticae (ex Stellaria aquatica), P. stellariae-uliginosae (ex Stellaria alsine), and P. pseudostellariae (ex Pseudostellaria palibiniana). In addition, Peronospora specimens parasitic to Pseudostellaria davidii differed morphologically from P. pseudostellariae owing to the large and ellipsoidal conidia; this morphological discrepancy was also validated by the high genetic divergence between the two species. Peronospora casparyi sp. nov. is described and illustrated here.

The family Peronosporaceae, an obligate biotrophic group of Oomycota, causes downy mildew disease on many cultivated and ornamental plants such as beet, cucumber, grape, onion, rose, spinach, and sunflower. To investigate the diversity of Peronosporaceae species in Korea, we performed morphological analysis for dried plant herbariums with downy mildew infections by two largest genera, Peronospora and Plasmopara. As a result, it was confirmed that there are five species of Peronospora and two species of Plasmopara, which have been so far unrecorded in Korea, as well as rarely known in the world; Pl. angustiterminalis (ex Xanthium strumarium), Pl. siegesbeckiae (ex Siegesbeckia glabrescens), P. chenopodii-ambrosioidis (ex Chenopodium ambrosioides), P. chenopodii-ficifolii (ex Chenopodium ficifolium), P. clinopodii (ex Clinopodium cf. vulgare), P. elsholtziae (ex Elsholtzia ciliata), and P. lathyrina (ex Lathyrus japonicus). In addition, their phylogenetic relationship was inferred by molecular sequence analysis of ITS, LSU rDNA, and cox2 mtDNA. By rediscovering the seven missing species and barcoding their DNA sequences, this study provides valuable insights into the diversity and evolutionary studies of downy mildew pathogens.

Though several wood decay fungi have been reported in the world-wide, only about 600 wood decay fungi have been reported in Korea to date. Thus, the objective of this study was to secure resources for the wood decay fungi in Korea. We investigated wood decay fungi in Yeoninsan Provincial Park, Korea, and the collected specimens were identified based on ITS sequence analysis. Two species were unrecorded species in Korea: Postia hirsuta (Polyporales, Basidiomycota) and Hyphodontia reticulata (Hymenochaetales, Basidiomycota). Another species was previously reported without detailed description: Ceriporia alachuana (Polyporales, Basidiomycota). Here, we provided additional detailed microscopic features and phylogenetic analysis of these species.

의도적 도입 또는 비의도적 도입에 의해 국내에 확산되고 있는 침입외래식물은 경제적, 환경적인 해를 가할 수 있으며 자생종의 감소나 절멸을 초래하는 등 생물다양성에 부정적인 영향을 미치는 것으로 알려져 있다. 특히 습지나 저수지 및 하안 생육지는 스트레스와 교란에 의해 외래식물 유입과 확산이 용이하므로 국립수목원에서는 이를 관리하기 위한 연구를 지속적으로 수행하고 있다. 본 연구에서는 수원시 하천변에서 발견된 바늘꽃과에 속하는 L. peploides subsp. montevidensis (Spreng.) P.H. Raven가 생태계교란종으로 확산될 우려가 있어 본 종에 대한 기재, 도해, 칼라도판 등을 첨부하여 침입외래식물 관리를 위한 기초자료를 확보하고자 한다.

우리나라 토양 중의 효모 종 다양성 조사의 일환으로 서울특별시 H동 허브공원 일대 토양 29점을 2015년 5월에 수집하여 9종 15균주의 야생효모들을 polymerase chain reaction 을 이용한 internal transcribed spacer 부위와 26S rDNA의 D1/D2 부위의 염기서열 상동성 비교법을 이용하여 분리, 동정하였다. 이들 가운데 Cryptococcus laurentii 2균주를 포함하는 Cryptococcus속 균이 8균주로 가장 많이 분리되었고 Saccharomyces cerevisiae도 2균주 분리되었다. 이들 가운데 아직까지 우리나라 미생물 관련 학술지에 보고되지 않은 Candida boleticola SU14-2와 Candida novakii SU6-2, Cryptococcus podzolicus SU18-2 등의 미기록 효모들을 선별한 후 이들의 미생물학적 특성을 조사한 결과 Candida novakii SU6-2는 자낭포자와 의균사를 형성하였고 Candida boleticola SU14-2는 5% NaCl을 함유한 YPD 배지에서 생육하는 호염성 효모이었다.

This is the third series of catalogs reporting on Korean species discovered through the 'Discovery of Korean Indigenous Species'. This catalog includes 22 species of invertebrates, excluding insects. The catalog includes the scientific name, an abridged list of synonyms, collection sites, distribution, diagnosis, and figures for each species. Additionally, we provide the newly assigned Korean name, specimen voucher, and, if available, mitochondrial CO1 or 16S gene sequences of the species listed. All species identified and documented here will be officially listed on the 'National Species List of Korea', a database maintained by the National Institute of Biological Resources(NIBR).
