Studies on the diversity of indigenous fungi were conducted in the central districts of South Korea from 2008 to 2013. During the studies, potentially unrecorded agarics were collected. All specimens collected in this study were examined morphologically and phylogenetic analysis was also performed. They were identified as Galerina sideroides and Gymnopus luxurians. These fungi have never been reported in South Korea. We report them here with detailed descriptions and figures.

As a part of studies on the fungal flora of Korea, authors have collected over 60 higher fungi specimens during summer season in 1993 in Mt. Hungjung which was located in eastern part of Korea. Among them two genera are new to Korea: Neobulgaria Petrak and Melastiza Boudier. Following five species are recorded for the first time in Korea: Psilocybe xeroderma Huijsm, Galerina vittaeformis (Fr.) Singer var. vittaeformis f. vittaeformis (Fr.) Singer, Gyromitra infula (Schaeffer ex Fries) Quelet, Neobulgaria pura (Fries) Petrak and Melastiza chateri (W. G. Smith) Boudier, for which Korean common names are designated in this present paper. All color names and terms within quotation marks are taken from Kornerup and Wanscher 1983, Methuen handbook of colour. The specimens are all deposited in the RDAGB's herbarium.

The fungi play important roles in maintaining the balance and homeostasis of natural ecosystems. We investigated fungal specimens indigenous to the Gayasan National Park located in the deep inlands of southeastern Korea from 2017-2020. Six fungal species in the Korean macromycota-Chiua olivaceoreticulata, Entoloma conchatum, Galerina sulciceps, Hebeloma radicosoides, Spongiporus gloeoporus, and Tricholoma sinoacerbum-were identified based on morphological characteristics and rDNA sequences. The six fungal speices were newly revealed on the Korean Peninsula, and it supports that the continuous investigaton is the best way to realize the mycosis.

Most known species in the Strophariaceae are decomposers and grow on various kind of organic matter. Approximately 18 genera and 1,316 species in the Strophariaceae have been reported worldwide. Through an ongoing survey of indigenous fungi in Korea, 29 specimens belonging to the Strophariaceae were collected from 2012 to 2016. These specimens were identified based on morphological characteristics and molecular analysis of internal transcribed spacer sequences. Fifteen taxa were confirmed, with eight species matching those previously recorded. Seven species in five genera were shown to be new records in Korea: Galerina marginata, Gymnopilus crociphyllus, Gymnopilus picreus, Hebeloma birrus, Hebeloma cavipes, Pholiota multicingulata, and Psilocybe thaizapoteca. In this study, we provide detailed morphological descriptions of these species and investigate their evolutionary relationships by constructing phylogenetic trees.

α-Amanitin and β-amanitin are highly toxic bicyclic octapeptides responsible for the poisoning of poisonous mushrooms such as Amanita, Galerina, and Lepiota by inhibiting RNA polymerase II, DNA transcription, and protein synthesis. A sensitive, simple, and selective liquid chromatography-high resolution mass spectrometric method using parallel reaction monitoring mode was developed and validated for the simultaneous determination of α- and β-amanitin in mouse plasma to evaluate the toxicokinetics of α- and β-amanitin in mice. Protein precipitation of 5 μL mouse plasma sample with methanol as sample clean-up procedure and use of negative electrospray ionization resulted in better sensitivity and less matrix effect. The calibration curves for α- and β-amanitin in mouse plasma were linear over the range of 0.5-500 ng/mL. The intra- and inter-day coefficient of variations and accuracies for α- and β-amanitin at four quality control concentrations were 3.1-14.6% and 92.5-115.0%, respectively. The present method was successfully applied to the toxicokinetic study of α- and β-amanitin after an oral administration of α- and β-amanitin at 1.5 mg/kg dose to male ICR mice.
