An exotic parasitic wasp Anisopteromalus apiovorus of Pteromalidae was newly recorded in Korea. Specimens of this species have been collected in Gimhae of Korea since 2012. External morphology of this species was described in detail and diagnostic differences of this species from the related species and the host insect were also given. The funicle segments of female antennae are 1.2 to 1.5 times longer than those of Anisopteromalus calandrae, an sister species. Body color is gold-glossy black and with dense creamy-white hairs on the surface. This exotic species has been originated from the African continent including Democratic Republic of Congo and Cote d'Ivoire, and then intruded into other countries, for instance, Korea. This is the first distribution record of this species except the country of origin after original description as a new species. Although little is known about the life history or ecology of this species, we found that a new host of this small parasitic wasp is Lasioderma serricorne of coleoptera through present study. And this species possibly be a new agent of biological control for economic pests. It was presumed that the invasion of Anisopteromalus apiovorus into Korea was prior to November of 2012.

Colletotrichum acutatum species complex is one of the most important groups in the genus Colletotrichum with a high species diversity and a wide range of host plants. C. acutatum and related species have been collected from different plants and locations in Korea and deposited into the Korean Agricultural Culture Collection (KACC), National Institute of Agricultural Sciences since the 1990s. These fungal isolates were previously identified based mainly on morphological characteristics, and a limitation of molecular data was provided. To confirm the identification of species, 64 C. acutatum species complex isolates in KACC were used in this study for DNA sequence analyses of six loci: nuclear ribosomal internal transcribed spacers (ITS), betatubulin 2 (TUB2), histone-3 (HIS3), glyceraldehyde3-phosphate dehydrogenase (GAPDH), chitin synthase 1 (CHS-1), and actin (ACT). The molecular analysis revealed that they were identified in six different species of C. fioriniae (24 isolates), C. nymphaeae (21 isolates), C. scovillei (12 isolates), C. chrysanthemi (three isolates), C. lupini (two isolates), and C. godetiae (one isolate), and a novel species candidate. We compared the hosts of KACC isolates with "The List of Plant Diseases in Korea", previous reports in Korea and global reports and found that 23 combinations between hosts and pathogens could be newly reported in Korea after pathogenicity tests, and 12 of these have not been recorded in the world.

A newly recorded species, Schoenoplectiella ${\times}$uzenensis (Ohwi ex T. Koyama) Hayasaka, was found in Chosan Lake, Gosu-myeon, Gochang-gun, Jeollabuk-do, Korea. Schoenoplectiella ${\times}$uzenensis differs from its related species in having short rhizomes and 1 to 3 spikelets showing inflorescence. Schoenoplectiella triangulata has very short rhizomes and 520 spikelets with inflorescence. Schoenoplectiella lineolata has long creeping rhizomes and 1 spikelet showing inflorescence. We propose the new Korean name of 'Go-Chang-Go-Rang-Ei' based on its initial collection site. A description, line drawing, color photographs, table, and a species key of Korean Schoenoplectiella are provided for species identification.

Morphological and molecular information about two microfilamentous endophytic algae of the Grateloupia lanceolata or Bryopsis sp. from Korea is given. Of two endophytes, Phaeophila dendroides is endophytic in Grateloupia lanceolata. It is green in color and composed of uniseriate branched filaments with long setae. Each cell had several pyrenoids. Undulate or twisted Phaeophila-type hair developed from vegetative cells. Dilabifilum arthropyreniae is endophytic in Bryopsis sp. The frond of this species consists of frequently irregular, branching uniseriate filaments. Each cell had a single pyrenoid without hairs. Sporangia were not observed. The ends of the filaments were curved. In the phylogenetic tree, based on tufA and ITS sequences, these two species are nested in the same clade as Phaeophila dendroides and Dilabifilum arthropyreniae, respectively. In this study, these two species are newly recorded in the Korean marine algal flora, based on the morphological and molecular data.

Two siphonous green algae were collected from the eastern coast of Korea. These species share the typical features of Derbesia sporophytes, such as erect and prostrate siphonous filaments and the presence of basal septum in lateral branches. One is characterized by the combined features of a relatively small tufted sporophytic thalli arising from a rhizoidal base, subdichotomously branched filaments with a basal septum and one pyrenoid per subspherical to lenticular chloroplast. The other shows a larger sporophytic thallus, sparsely subdichotomously branched filaments with a basal septum and one pyrenoid per spherical chloroplast. In a phylogenetic tree based on rbcL sequence, the two above-mentioned Korean algae nest in the same clades as Derbesia minima and D. indica, respectively. The genetic distance between the sequences within the clades was 0.5-0.8%, which is considered to be included in the intra-specific range for the genus. These two siphonous Korean algae are identified as D. minima and D. indica, respectively, based on the morphological and molecular analyses. These species are newly recorded in the Korean marine algal flora herein.

Creeping ctenophores, Coeloplana species, were collected by SCUBA divers throughout the year (November 2006 to June 2010) from the branches and polyp masses of encrusting dendronephthyas at a depth of 20-32m off Munseom Island (Seogwipo-si, Jeju-do, Korea). A single individual of a newly recorded species in Korea, Coeloplana bocki Komai, 1920, was collected together with C. anthostella from the same location on 16 August 2009. A large number of individuals of each species were subsequently collected from the host Dendronephthya aff. dendritica on 20 June 2010. C. bocki can be distinguished from C. anthostella Song and Hwang, 2010 and C. komaii Utinomi, 1963 by its unique blue and orange colored stripes, and/or the branching and anastomosing milky-white stripes encircling the aboral sense organ towards the margin. The detailed morphology and molecular sequence information (nuclear 18S rDNA, internal transcribed spacer 1, and mitochondrial cox1 gene sequences) for C. bocki is provided, and C. bocki and C. anthostella are compared.

Most of lichens are formed by Ascomycota, less than 1% are lichenized Basidiomycota. The flora investigation of lichenized Ascomycota of South Korea has been well studied in the past three decades; however, prior to this study, none of basidiolichens was discovered. During the recent excursion, an unexpected clavarioid basidiolichen, Sulzbacheromyces sinensis was collected. Morphology and ecology has been recorded in detail. DNA was extracted, and ITS, 18S, 28S nuclear rDNA were generated. In order to further confirm the systematic position of the Korean specimens, maximum likelihood and Bayesian inference analysis including all the species of the order Lepidostromatales were conducted based on the ITS. As a result, the phylogenetic tree of the order Lepidostromatales was reconstructed, which differed from the previous studies. The inferred phylogenetic tree showed that species of Sulzbacheromyces in three different continents (Asia, South Africa and South America) were separated into three clades with support. In this study, the species worldwide distribution map of Lepidostromatales was illustrated, and S. sinensis had a widest distribution range (paleotropical extend to the Sino-Japanese) than other species (paleotropical or neotropical). Prior to this study, the range of distribution, southernmost and northernmost points and the fruiting time of S. sinensis were recorded, and the genus Sulzbacheromyces was firstly reported from Korean peninsula and Philippines.
