  • A new species, Fimbristylis drizae J. Kim & M. Kim, is named and described from Sucheong Lake, Jeongeup-si, Jeollabuk-do, Korea. Fimbristylis drizae shares several characters (five-angled culm, 1-2 bladeless sheath, and compound anthela inflorescence) with the related species F. diphylloides Makino. It is, however, distinct from F. diphylloides, which has two to three stigmas, ovate spikelets, two stamens, a blackish brown scale, and a roadside habitat. In contrast, the new species has two stigmas, oval spikelets, one (or rarely two) stamens, a yellowish brown scale, and a lakeside habitat.

  • In the present paper author investigated the symptom, pathogenic fungus and pathogenicity of Endothia canker of Carpinus laxiflora in Korea, and made clear the indistinct discription on its pathogen in the past. 1. The pathogen is identified as Endothia fluens (Schw.) Shear et Stevens. The discription is recorded as follows: Stromata cortical, erumpent, spherical or conical, outer yellowish-brown and inner yellowish, 0.5 to 2.5 mm in diameter; perithecia irregularly embeded in the bottom of stroma, 7 to 23 in a stroma usually spherical to elliptical or irregular, 235 to $370{\mu}$ in diameter, with black slender necks; each neck open the papilliate ostiole to the surface, about 250 to $400{\mu}$ in length; asci clavate or fusoid, colorless, 31.16 to 42.64 by 6.54 to $8.20{\mu}$ in size, average 37.02 by $6.84{\mu}$, with 8 ascospores in double line; ascospores elliptical, ovate or cylindrical, with rounded ends, hyaline, 1-septate, not constrict at the septum, 6.51 to 9.30 by 3.16 to $3.72{\mu}$, average 7.61 by $3.44{\mu}$ in size; pycnidia formed abundantly in stroma. spherical at first but later irregular large cavity by fussing each other; pycnospores oblong or rod-shaped, hyaline, non-septate, 3.8 by $1.9{\mu}$ in size; spore-horn formed abundantly under moist condition. 2. The pathogen is wound parasite invading the hosts through the wound. But after the infection is established, expanding the disease lesion is swiftly vigorus.

  • Umbelliferae medicinal crops have low germination under natural condition. Special objective of this study is to investigate morphological characteristics of seeds and effects of environmental factors such as light and temperature on their germination and seedling growth in Umbelliferae plants, using them as oriental medicine materials. Fruits of Umbelliferae are bi-partite type and form 2 seeds. Their oil canals and funiculus or carpaphore has apparently specific shape. Seed shape of Buplerum falcatum, Ligusticum acutilobum and Foeniculum vulgare are oblong, Ledeboutiella seseloides, Angelica dahurica, Angelica gigas elliptic, and Ostericum koreanum ovate. Color of seed coats varied from yellow to dark brown. Seed size was 3.2 to 6.9 mm in length, 1.7 to 4.9 mm in width. One thousand-seed weight of Buplerum falcatum was lowest(at 1,660 mg) and Ledebouriella seseloides and Angelica gigas were relatively highest(at 3,970 mg) having larger size than any others. Optimum temperatures for seed germination and seedling growth ranged from 20 to $25^{\circ}C$ and especially temperature at $25^{\circ}C$ improved seed germinations of Ledebouriella seseloides, Angelica dahurica and Ligusticum acutilobum regardless of light condition.

  • Herein, we report a new record of Arna bipunctapex (Hampson) and a new species, Euproctis fulvatus sp. nov. in Korea; both are Lymantriine moths. Arna bipunctapex is distinguished by a relatively large wingspan with two black dots and a small dot between these black dots in the apical region of a yellowish forewing. The male genitalia of A. bipunctapex can be distinguished by the lack of a process on the sacculus of valva while the female genitalia can be distinguished by an antrum that is basally flat with two lateral digitate arms. Euproctis fulvatus is distinguished by yellowish wings with a medially curved central fascia of the forewing. The male genitalia can be distinguished by the bifid, digitate uncus and the simple, square-shaped valva with a distal strong invaginated margin. The female genitalia can be distinguished by the long, medially twisted, ductus dursae with simple antrum posteriorly strongly sclerotized and ovate corpus bursae without signum. Larvae of E. fulvatus are distinguished by a black head with a pair of long, black, lateral tufts, dorsum with 10-11 white intersegmental dots and bright red setal warts on T2-A8, and bright red glands on A6 and A7.

  • Cyanobium is a genus of picoprokaryotic cyanophytes, which includes species worldwide. The present study investigated the morphology, ultrastructure, and molecular phylogeny of the unrecorded genus Cyanobium Rippka & Cohen-Bazire 1983 and species Cyanobium gracile Rippka & Cohen-Bazire 1983. A C. gracile culture from a freshwater sample collected from the Adongji pond was established by single-cell isolation. Morphological data were analyzed using light and transmission electron microscopy. C. gracile lives as solitary cells without gelatinous envelopes and is ovate, oval, or shortly rod-shaped. Thylakoids are laid along the cell walls, with three thylakoid membranes parallel to each other. Nucleoplasm was observed in the center of the cell. Molecular phylogeny performed with data from 16S small subunit ribosomal DNA gene (SSU rDNA) sequences showed that the three strains of C. gracile, including the type strain (PCC6307) and a newly recorded strain (Adong101619), formed a distinct clade with a high supporting value (maximum-likelihood=100, pp=1.00). Based on morphology and molecular data, we report the newly recorded C. gracile in Korea.

  • Two feather mites, Brephosceles anatina Dubinin, 1951 (Analgoidea: Alloptidae) and Freyana anatina (Koch, 1844) (Pterolichoidea: Freyanidae), have been reported for the first time from the Eastern Spot-billed Duck, Anas zonorhyncha Swinhoe, 1866 (Anseriformes: Anatidae), in Korea. The genera Brephosceles Hull, 1934 and Freyana Haller, 1877 are new records of Korean fauna. The morphology of B. anatina is distinguished from three species of the lambda species group in having legs IV extending the level of setae e2 with the distal end of the tarsus in males, and the incision on the posterior margin of the hysteronotal shield triangular-shaped and distinctly longer than its greatest width in females. Freyana anatina is distinguished from F. nyrocae and F. obliquasetae in having setae ps1 with a rectangle bend in homeomorphic males, and setae ps1 obliquely ovate and divergent, with the inner canal going obliquely across the membranous part of these setae in females. This study provides morphological redescriptions of both feather mite species supplemented with partial sequences of mitochondrial cytochrome c oxidase subunit I(COI), based on specimens collected in Korea.

  • Selaginella austrotibetica, a new spikemoss species from China, is described. The species is epipetric and was found on a moss-covered rocky cliff by a riverbank. Morphologically, it is unlike any anisosporophyllous species in the genus Selaginella. However, it resembles species of the S. sanguinolenta group, especially similar to S. sajanensis in gross morphology, except for the characters of strobilus. The molecular phylogenetic analysis clearly showed that S. austrotibetica was nested within the anisosporophyllous species clade, forming a sister relationship with the clade of S. vaginata and S. xipholepis, and distinct from the S. sanguinolenta group, including S. sajanensis. Although S. austrotibetica is sister to the clade of S. vaginata and S. xipholepis, the species can be clearly distinguished by its sparse leaves on branches, dorsal leaves that are broad-ovate, base obtuse to rounded, margin denticulate or very shortly sparsely ciliolate, and leaves that are slightly thick and shiny. Therefore, we described Selaginella austrotibetica as a new species and discuss its phylogenetic relationships within the genus Selaginella.

  • A new species, Elsholtzia byeonsanensis M. Kim is named and described from Byeonsan, Jeollabukdo Province, Korea. Molecular data confirmed that this new taxon was distinguished from other congeneric species. Elsholtzia byeonsanensis shares several characteristics (secund spikes, ovate leaves, long corolla length, etc.) with its related species E. splendens, but it is distinct from E. splendens which has a large plant, green stem color, chartaceous leaf textures, non-shiny leaf surfaces, pubescent petioles, pubescent leaf blade surfaces, pubescent bract surface, and open woodland habitats by having a small plant, purple stem color, coriaceous leaf textures, shiny leaf surfaces, glabrous petioles, glabrous leaf blade surfaces, glabrous bract surface, and marine habitats.
