Da-Lat is a hilly area located in southern Vietnam. Macrofungal diversity of Da-Lat was investigated from 2018 to 2019. A total of 468 macrofungal specimens was collected and identified using the modern species concept and taxonomic and phylogenetic analyses. Among them, internal transcribed spacer(ITS) region of 401 specimens were successfully sequenced and compared with those of related species retrieved from GenBank. In total, 180 specimens were identified at the species level. The sequenced specimens were classified into 2 phyla, 13 orders, 38 families, 93 genera, and 124 species. The remaining 221 specimens (175 species) did not match the species level. This study is the first well-documented taxonomic list of macrofungi collected from southern Vietnam.

Candida속 효모 27종이 표준 균주를 대상으로 세포내 지방산 조성을 기체 크로마토그래피로 분석하여, 함유 지방산의 종류와 함량비를 근거로 27종이 균주를 3개의 분류군으로 나누었다. 이들 지방산 분석에 의한 분류군을 Candida속의 다른 분류학적 결과들인 coenzyme Q 분자종의 종류, DNA 염기함량 분석, ITS 부위의 제한효소 절단 다형질의 양상, 리보좀 소단위 RNA 유전자의 염기배열 보고와 비교 분석하였다. 그 결과 같은 분류군에 위치하는 균주들 사이의 연관 관계가 거의 일치하였다. 다라서 세포내 지방산 분석은 Candida속 규준들을 유전적 동질성을 갖는 균주들로 분류하는 수단으로 사용될 수 있으며, 유전적으로 매우 다양한 균주들의 집단으로 알려진 Candida속에 관한 분류적 고찰에 일차적으로 사용될 수 있는 유용한 수단임을 알 수 있었다.

The clustering analysis and comparison of male genitalia of Silpha perforata complex were carried out to decide the taxonomic status of the population from Jejudo Is., Korea. One hundred and five individuals from Korea, Japan, and China were examined for the present study. Based on the result, the population of Jejudo Is. was treated as intraspecies of Silpha perforata with a morphological variation.

A taxonomic study of the genus Delta de Saussure, 1855 from Vietnam is presented. A total of four species are recorded: D. campaniforme campaniforme (Fabricius, 1775), D. conoideum (Gmelin, 1790), D. esuriens esuriens (Fabricius, 1787), and D. pyriforme pyriforme (Fabricius, 1775). Of these, D. campaniforme campaniforme was first recorded from Vietnam by de Saussure et al., 1904, under the name Eumenes esuriens and is now reconfirmed to occur in Vietnam after more than 100 years, and D. conoideum is newly recorded from Vietnam. A key to species based on morphological characters is given with illustrations, and distributional records in Vietnam are also provided.

The water deer, Hydropotes inermis (Cervidae), is native to China and Korea and has two subspecies of the Chinese water deer (Hydropotes inermis inermis) and Korean water deer (Hydropotes inermis argyropus). To date, only the Korean water deer has been reported in South Korea. In this study, however, an intraspecific phylogeny and haplotype analysis based on mitochondrial cytochrome oxidase I indicated that both Korean and Chinese water deer are found in South Korea. The populations of the two Korean genetic lineages did not show distinct geographic distributions. Further morphological studies on the Korean water deer will be required to confirm its taxonomic status.

In this study, the phylogenetic relationships among the genera Alsidium C. Agardh and Bryothamnion $K{\ddot{u}}tzing$ were investigated. Phylogenetic analyses using the plastid-encoded markers rbcL, psbA, and the mitochondrial barcode region (COI-5P) resolved a well-supported clade that included the species Alsidium corallinum, Bryothamnion seaforthii, and B. triquetrum. Our results indicated that taxonomic recognition of the genus Bryothamnion is not supported and two species of Bryothamnion are reallocated to Alsidium. A reexamination of the morphological definition of Alsidium is provided with an updated diagnosis of the genus and a morphology-based comparison of species that are currently circumscribed under this generic name. Furthermore, we reviewed morphological differences and similarities between Alsidium and the genus Digenea, both belonging to the tribe Alsidieae, discussing the most relevant morphological characters.

Morphological and anatomical characters of Amphiroa misakiensis Yendo are investigated with field materials and taxonomic accounts are given to the species. The plants grow on rocks, mussels or non-articulated corallines from the subtidal zone of Cheju island, and is characterized by recumbent and spreading habit from the substrate. The species is well defined by about 4 cm height, loosely tufted thallus with irregularly dichotomous branches, flat and irregularly broad intergeniculum in upper part, geniculum developing by cracking and sloughing of calcified cortical tissue overlying uncalcified genicular tissue, five to thirteen-tiered geniculum with unequal length, and conceptacles buried in cortices of intergeniculum. Reproductive structures in tetrasporangial, male and female plants are typical of Amphiroa. The structure and developmental patterns of conceptacles are very similar to those shown in previous studies.

To clarify the species of genus Deutzia (Saxifragaceae, s. l.) in Korea, the taxonomic description was undertaken and interspecific relationships was discussed based on the external morphology with the light and scanning electron microscopes and the distributional pattern with specimens deposited in the herbaria. The presence or absence, number of rays, position and frequency of the stellate trichome, inflorescence and the morphology and venation pattern of petal were approved as the good characters to classify the Korean Deutzias. Although 17 kinds of Deutzia were reported in Korea hitherto, 9 kinds were excluded owing to the taxonomic treatment based on the comparative external morphology and the distributional uncertainty. Thus genus Deutzia in Korea could be rearranged as 2 sections, 3 subsection, 7 species and 1 variety. Among them, 4 species were considered as the endemic species in Korea.

Taxonomic identification is fundamental to all microbiology studies. Particularly in metagenomics, which identifies the composition of microorganisms using thousands of sequences, its importance is even greater. Identification is inevitably affected by the choice of database. This study was conducted to evaluate the accuracy of three widely used 16S databases-Greengenes, Silva, and EzBioCloud-and to suggest basic guidelines for selecting reference databases. Using public mock community data, each database was used to assign taxonomy and to test its accuracy. We show that EzBioCloud performs well compared with other existing databases.

Two species of Leycesteria, L. gracilis (Kurz) Airy Shaw and L. formosa Wall. (Caprifoliaceae), from the Lao Cai and Yen Bai Provinces are reported here as a new generic record for the flora of Vietnam. During floristic surveys of northern Vietnam, L. gracilis and L. Formosa were encountered. A critical morphological study of all the collected specimens and the type of materials consulting the relevant literature led us to confirm the identity of our collected specimens as L. gracilis and L. formosa. The genus differs from other Vietnamese genera of Caprifoliaceae by the presence of a spike inflorescence or flowers in sessile whorls of 6. Taxonomic notes, description, and photographs are provided, together with short notes on the distribution, ecology and phenology of the two species.
