The genus Macrolepiota (Agaricales, Basidiomycota) is easy to recognize at the genus level because of big, fleshy basidiocarps with squamules covering the pileus; a single or double annulus; and big, thick-walled basidiospores with a germ pore. However, morphological identification is often unreliable in Macrolepiota due to similar morphological features among species. Due to the uncertainty of previous morphological identification in the genus Macrolepiota, it is necessary to re-examine Korean Macrolepiota using molecular data. We reexamined 34 Macrolepiota specimens collected from 2012 to 2018 in Korea using a reverse taxonomic approach, whereby species identification was first done based on the internal transcribed spacer (ITS) region analysis, followed by morphological confirmation. We identified the presence of four species: M. detersa, M. mastoidea, M. procera, and M. umbonata sp. nov. Two species (M. detersa and M. mastoidea) were previously unrecorded from Korea and M. umbonata is a new species. Detailed descriptions of all four species and taxonomic key are provided in this study. Macrolepiota procera and M. umbonata are distributed through the country, but M. detersa and M. mastoidea are distributed only in limited areas. According to our results, the combination of ITS locus and morphology proved to be a robust approach to evaluate the taxonomic status of Macrolepiota species in Korea. Additional surveys are needed to verify the species diversity and clarify their geographic distribution.

Three naturalized taxa in Korea such as Scleranthus annuus L., Verbena bonariensis L. and Hordeum jubatum L. were newly recorded. Short descriptions and illustrations for the these species were provided. Especially, Scleranthus L. is first recorded as a new genus of Korean flora.

A fungal survey that targeted the tribe Arachnopezizeae (Hyaloscyphaceae, Helotiales) was conducted in Korea. One variety belonging to Proliferodiscus and one species belonging to Rodwayella are recorded for the first time from Korea. Proliferodiscus inspersus var. magniascus differs from P. earoleucus by its amyloid reaction in ascal apices and larger asci. Rodwayella citrinula is distinguished from other members of the genus by small ascospores and its occurrence on grasses. The descriptions, illustrations and cultural characteristics of the species are provided.

A new distribution of Trichosanthes cucumeroides (Ser.) Maxim. ex Franch. & Sav. is discovered in Korea. This species was collected from forest margins on Ando Island, Ando-ri, Nam-myeon, Yeosu-si, in Jeollanam-do. T. cucumeroides is clearly distinguished from other species of the genus by having three- or five-lobed leaf blades, linear-lanceolate and minute bracts with entire margins, and oblong to triangular-ovoid seeds. Here, we provide precise description, a taxonomic key to the Korean Trichosanthes species, illustrations, and photographs of its habitat. The Korean name for the species is established as 'Bul-geun-ha-neul-ta-ri' considering the reddish color of its fruit.

This study presents the first review of the family Oecophoridae, except the genus Promalactis which was reported previously by author, in Korea. From the result of the study thirteen species belonging to nine genera are reported for the first time from Koea. For the study a general characteristic of species was described and also genitalia of males or females were illustrated. Host plants of larva known to date are also listed.

A single juvenile malacanthid specimen (Hoplolatilus chlupatyi) was collected from the South Sea of Korea and identified by DNA barcoding. This species is readily distinguished from other malacanthid species in having well developed rostral spine and elongated spines in the posttemporal and preopercle. A molecular analysis based on mitochondrial DNA COI sequences showed that this species is matched to adult H. chlupatyi (genetic distance = 0.005). Therefore, this is the first record of H. chlupatyi in Korea. We propose new Korean names, "Mu-ji-gae-og-dom-sog" for the genus Hoplolatilus and "Mu-ji-gae-og-dom" for the species H. chlupatyi.

Specimens belonging to the genera Mycena and Collybia which have been preserved in the herbarium of National Institute of Agricultural Sciences and Technology, Suwon, Korea were investigated. Among them, four species were confirmed to be Hydropus species viz Hydropus marginellus, H. nitrata, H. erinensis, and H. floccipes. Authors registered them to the Korean mycoflora with full descriptions, illustrations and Korean names.

Arthrinium (Ascomycota, Apiosporaceae) is a major marine fungal genus. Three Arthrinium species were reported previously, but not fully described. We isolated the two species A. arundinis and A. saccharicola from Sargassum sp. brown algae in Jeju Island, Korea. These species have not been previously reported in Korea. We described these species in detail and performed a phylogenetic analysis based on the nucleotide sequences of the EF1-${\alpha}$ and ${\beta}$-tubulin genes.

Smithistruma japonica(lto) unrecorded species of Dacetini tribe in Korea was found in Is. Kekumdo, Chonnam Province and named Saw teeth scale ant. The form-characteristics difference between Smithistruma japonica(Ito) and Strumigenys lewisi Cameron was discribed with the result of observation by the scanning electron microscope(SEM). Total species of Dacetini tribe in Korean contained two species in two genus.
