1990년 3월부터 1992년 2월까지 우리나라의 국립공원지대(國立公園地帶)와 일부지역(一部地域)과 일부도서(一部島嶼)를 중심으로 목재부후균류(木材腐朽菌類)를 탐색하여 자낭균류(子?菌類)와 목이류(木耳類)의 균류(菌類)들을 동정하고 기존의 해당 목재부후균류(木材腐朽菌類)와 함께 분류한 결과 52 종(種), 1 아종(亞種), 및 1 품종(品種)으로 집계되었으며 그중 2 속(屬) 3 종(種)은 국내 미기록(未記錄)으로 밝혀졌다. 본 연구를 통하여 방석꼬투리 버섯속(屬) (신칭(新稱), Hypoxylon) 과 주발목이속(木耳屬) (신칭(新稱), Femsjonia)이 미기록속(未記錄屬)으로, 큰방석꼬투리버섯 (신칭(新稱), Hypoxylon punctulatum), 분홍좀목이 (신칭(新稱), Exidia recisa), 그리고 노란주발목이 (신칭(新稱), Femsjonia pezizaeformis)가 미기록종(未記錄種)으로 확인되어 한국산(韓國産) 균류목록(菌類目錄)에 새로이 추가 되었다.

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.

An improved method for extracting high quality and quantity RNA from a jelly mushroom and a dimorphic fungus-Tremella fuciformis which is especially rich in polysaccharides, is described. RNA was extracted from T. fuciformis mycelium M1332 and its parental monokaryotic yeast-like cells Y13 and Y32. The A260/280 and A260/230 ratios were both approximately 2, and the RNA integrity number was larger than 8.9. The yields of RNA were between 108 and $213{\mu}g/g$ fresh wt. Downstream molecular applications including reverse transcriptional PCR and quantitative real-time PCR were also performed. This protocol is reliable and may be widely applicable for total RNA extraction from other jelly mushrooms or filamentous fungi rich in polysaccharides.

Background : The white jelly mushroom (Tremella fuciformis), one of the most popular edible fungi, has medicinal properties. However, the effects of T. fuciformis in skin whitening or anti-wrinkle efficacy has not been defined to date. The aim of the present study was to investigate the effects of T. fuciformis extracts on whitening and anti-wrinkle efficacy in skin cells. Methods and Results :We prepared T. fuciformis extracts with water. The extracts ($80^{\circ}C$) contained 12.11 mg/g polyphenol and 8.54 mg/g flavonoid concentration. T. fuciformis extracts markedly decreased melanin contents and tyrosinase activity in ${\alpha}$-MSH-stimulated melanocytes (B16F10 cells). In addition, the mRNA expression of melanin formation factors, such as microphthalmia-associated transcription factor (MITF), tyrosinase-related protein-1 (TRP-1) and tyrosinase-related protein-2 (TRP-2) were significantly down-regulated in ${\alpha}$-MSH-stimulated melanocyte. Furthermore, T. fuciformis extracts increased the synthesis of type I procollagen and reduced mRNA expression of matrix metalloproteinase 1 (MMP-1) in the human dermal fibroblast (HDFn cells). These data indicated that T. fuciformis extracts induce repression of cellular melanogenesis and protect against wrinkles caused by UVB-stimulated damage. Conclusions : Thus T. fuciformis extracts could be a cosmetic candidate for skin whitening and anti-wrinkle effects.
