Two Entoloma species, E. eugenei and E. subaraneosum, are described here as newly recorded species in Korea. These two species were recently described from far Eastern Asia, Primorsky Territory of Russia, and Jilin province of China, respectively. Here, these species were reported based on internal transcribed spacer and partial large subunit of ribosomal RNA sequences, and macro- and micro-scopic characteristics for the first time in Korea.

Here we reported two unrecorded naturalized species from Korean flora. Andropogon virginicus L. of Graminaeae and Euphorbia postrata Aiton of Euphorbiaceae are collected from Dong-gu, Ulsan-si and Sinjindo-ri, Taean-gun, Chungcheongnam-do respectively. A. virginicus L. was easily distinguishable from Themeda triandras var. japonica Makino by keel on glume, 2-4 racemes and long hairy rachis. Thus, the new Korean name, 'Na-do-sol-sae', was given. E. postrata Aiton was cleary distinguished from related taxa by hairs on only edges of fruits. The new Korean name, 'Nu-un-ttang-bin-dae' was given considering the species epithet. Descriptions, illustrations and photographs showing habitat were given.

The Inocybaceae is a family of ectomycorrhizal fungi belonging to the Agaricales order. Most species in this family produce secondary metabolites, such as muscarine, psilocybin, and other compounds. In the present study, we conducted taxonomic studies on the Inocybaceae based on morphological and molecular phylogenetic analyses for the first time in Korea. As a result, seven species of Inocybaceae were newly recorded: Inocybe caroticolor, I. fuscidula, I. grammatoides, I. latibulosa, I. stellata, Inosperma shawarense, and Mallocybe malenconii. Among them, the genera Inosperma and Mallocybe were described for the first time in Korea. Relevant morphological characteristics, phylogenetic trees, and photographs are provided.

Two new species, Thelopsis ullungdoensis and Phylloblastia gyeongsangbukensis are described from Ullung-Do (Island), South Korea. The closest relatives from Europe and Korea are epiphytic Thelopsis flaveola which differs by their immersed or semi-immersed yellow ascomata, ascospores without halo and their habitat of smooth bark (mainly Fagus) in humid and cold climates. Thelopsis gangwondoensis differs by its bigger semi-immersed ascomata (600-700 ㎛ in diam.), oblong halonate ascospores (8-12 × 6-8 ㎛) and its habitat of smooth bark of deciduous trees. P. gyeongsangbukensis differs from its relatives within the genus in having 5-septate ascospores (22-26 × 6-8 ㎛), semi-immersed, subglobose ascomata with a flattened top (250-400 ㎛) and a thin, matt, uneven gray-brown to gray-green continuous thallus without isidia.

Auricularia (Auriculariaceae, Basidiomycota) is well-known jelly fungi, and most species are cultivated or utilized medicinally around the world. A total of 127 Auricularia specimens were collected during Korean mushroom forays by the Korea National Arboretum from 2008 to 2020. In this investigation, fungal barcode analysis and morphological examinations of 33 specimens were conducted and five Korean Auricularia species were identified. Of the species identified, A. americana, A. heimuer, and A. villosula were new to Korea, while A. auricula-judae which was previously identified in Korea, was not found. Herein, we discuss the Korean Auricularia species and provide a taxonomic key for their morphological identification.

Dracocephalum rupestre Hance is a perennial herb distributed across China, Mongolia, and Korea. This study reports the first complete chloroplast genome sequence of D. rupestre. The plastome is 151,230 bp long and exhibits a typical quadripartite structure comprising a large single-copy region of 82,536 bp, a small single-copy region of 17,408 bp, and a pair of identical inverted repeat regions of 25,643 bp each. It contains 130 genes, comprising 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis of D. rupestre and related species of Lamiaceae showed that the genus Dracocephalum is a monophyletic group, and D. rupestre is most closely related to D. psammophilum.

Heloniopsis orientalis (Liliaceae) is an important horticultural crop native to Korea. Under natural conditions, germination is poor and plant growth is delayed. Therefore, we have developed a vegetative propagation method to produce plants with vigorous growth characteristics via tissue culture. The regenerated shoots were then initiated directly from leaf explants on an MS medium containing either 0.5 to 2.0 mg/L 2,4-D or 1.0 to 3.0 mg/L BA. Healthy plantlets with adventitious roots were formed on the medium supplemented with 1.0 mg/L BA (81%). BA triggered callus initiation without caulogenesis or rhizogenesis, and callus formation was better on the half-strength MS medium than on the full-strength medium. This in vitro propagation protocol will be useful for conservation, as well as for mass propagation.

Melilotus dentatus (Waldst. & Kit.) Desf. is an invasive plant native to Europe, Russia, Uzbekistan, Mongolia and China. It was introduced to North America to create grazing areas for livestock; its growth has since become uncontrollable. Melilotus dentatus is now found in Namyang-eup, Hwaseong-si, Gyeonggi-do, South Korea as an alien plant. This species is morphologically similar to Melilotus suaveolens Ledeb. and Melilotus officinalis (L.) Lam. M. dentatus differs from other species based on its oblong leaflets, distinct teeth, two ovules, surface of the legume that is minutely reticulate-nerved or smooth, and seeds that are dark green to greenish brown. Here, we have provided a detailed description and photographs of the alien species M. dentatus as well as an updated key to five Melilotus taxa studied, which will help prepare a continuous monitoring and management plan.

Commelina caroliniana Water, was founded in Jongdal-ri (Gujwa-eup, Jeju Island) for the first time, is widely distributed arable land near the coast and roads. C. caroliniana belongs to Commelinaceae and native to Bangladesh, India. This species can be distinguished from its allied species in Korea by several characters as followings: apex acuminate and obovate shape spathes, flowers have blue 3 petals, maroon spot on the antherode, fruit with 5 seeds in 3 ovaries. C. caroliniana is well known for its strong fertility, which can outcompate native grasses and further negatively effect on the grassland ecosystem. The species has already introduced and widely distributed across much of southeastern US and some of Asian countries. Considering the case of C. caroliniana's diffusion capacity and influence on the ecosystem, management system for prevent their spreading are required through monitoring. Given the great potential of spread found in C. caroliniana, continuous monitoring may be required.
