  • Globose to clavate base-ball sized, pear shaped, fruiting bodies were found under the Himalayan cedar, Cedrus deodora at less fertile and poor sandy poor soil in the campus of Gyeongsang National University in Jinju, Korea. The fruiting body was at first, round to club-shaped, usually with a narrow, rooting base with yellowish rhizomorphs attached to it and lack a volva and a sterile base. The peridium of fruiting body was tough and crusty. The peridioles were white pea-like capsules in a blackish matrix. The color change to darker tints of brown at the top of the exterior peridium reflected the gradual ripening of the interior gleba and peridioles, which proceeded from the top downward to become a mass of spore dust, appearing as cinnamon brown at the apex of the vertical section. At around this stage, the peridium cracked open linearly, exposing the gleba with powdery spores mass released from overmatured peridioles. Spores were more or less round, warty or spiny, 10 to $12{\mu}m$; globose, cinnamon brown in powdery mass, with spines up to $2{\mu}m$ long. The thin peridium ruptured further in response to the disintegration of the peridioles, releasing the powdery spores, which proceeded until whole fruiting body disappeared leaving the dry spore dust coats in the vicinity. The absence of a capillitium is a distinctive characteristic that distinguishes the specimen from other puff-ball fungi and from most of earthballs. Based on the above characteristics, the specimen was identified as Poslithus tinctorius.

  • The entomopathogenic fungus Cordyceps militaris is a valuable medicinal ascomycete, which degenerates frequently during subsequent culture. To avoid economic losses during industrialized production, scratching stimuli of mycelia was introduced to improve the fruiting body production. The present results indicated that higher yields and biological efficiency were obtained from two degenerate strains (YN1-14 and YN2-7) but not from g38 (an insertional mutant in Rhf1 gene with higher yields and shorter growth periods). Furthermore, the growth periods of the fruiting bodies were at least 5 days earlier when the mycelia were scratched before stromata differentiation. Three ROS-scavenging genes including Cu/Zn superoxide dismutase (CmSod1), Glutathione peroxidase (CmGpx), and Catalase A (CmCat A) were isolated and their expression profiles against scratching were determined in degenerate strain YN1-14 and mutant strain g38. At day 5 after scratching, the expression level of CmGpx significantly decreased for strain g38, but that of CmSod1 significantly increased for YN1-14. These results indicated that scratching is an effective way to promote fruiting body production of degenerate strain, which may be related at least with Rhf1 and active oxygen scavenging genes.

  • Phellinus linteus has been traditionally used as a folk medicine for centuries in Oriental countries. and attracts a great interest owing to its plausible anti-tumor effect. The 70% ethanolic extract of its fruiting bodies was shown to contain strong anti-angiogenic and antioxidant activities in the previous work. (omitted)

  • Norcolensoic acid (1) was isolated from both the fruiting bodies and the liquid culture of Lachnum virgineum. The structures of 1 was determined using spectroscopic methods. Compound 1 was isolated for the first time from this fungus. Compound 1 showed moderate antibacterial and phytotoxic activities.

  • Two fungivorous Korean erotylid beetles-Triplax ainonia Lewis, 1887 and Triplax nagaoi Nakane, 1977 in the tribe Tritomini-were recorded for the first time from Korea. All Korean Triplax members are associated with the fruiting bodies of higher fungi and fungus-grown bark. Re-description, key to the species of Korean Triplax, photographs of adults, and line drawings of diagnostic characters and host fungi records are provided.

  • Over a million tons of spent mushroom substrate (SMS) are generated as by-products of mushroom cultivation every year in Korea. Disposal of SMS by mushroom farmers is difficult, therefore, recycling solutions that do not harm the environment are necessary. SMS consists of mushroom mycelia and residues of fruiting bodies, containing a variety of bioactive substances, such as extracellular enzymes, antimicrobial compounds, and secondary metabolites. This paper reviews utility of SMS for bioremediation, controlling plant disease, and production of lignocellulytic enzymes, organic fertilizer, and animal feed.

  • Dongchunghacho (Dong-Chong-Xia-Cho in Chinese) is one of entomogenous fungi that grow as parasites mainly to pupae or larvae. It includes many different genera such as Cordyceps, Paecilomyces, Torrubiella and Podonectria. The ethanolic extract of Cordyceps scarabaeicola, prepared from its fruiting bodies, showed significant inhibitory activity on angiogensis, which was detected by chick embryo chorioallantoic membrane (CAM) assay. The ethanolic extract of media-cultured Paecilomyces japonica also showed significant anti-angiogenic activity in CAM assay. (omitted)

  • Ganoerma lucidum의 인공재배(人工栽培)로 얻은 자실체(子實體)의 형태적(形態摘) 특성(特性)을 기초(基礎)로 계통(系統)을 분류(分類)하고 전기영동특성(電氣泳動特性)과의 관련성(關聯性)을 검토하였다. 영지균은 버섯의 형태(形態)와 윤문(輪紋)의 유무에 따라 4계통(系統)으로 분류(分類)되었으며 그중 편각 윤문형(輪紋形)이 가장 많았고 전형적 녹각형은 소수였다. 자실체(子實體)의 모양 즉 편각과 녹각, 갓 표면(表面)의 윤문(輪紋) 유무(有無)는 유전성(遺傳性)이었다. 영지균사(菌絲) 및 자실체(子實體)의 전기영동(電氣泳動)에 의한 단백질(蛋白質), Peroxidase, Esterase 및 Leucine Amino Peptidase Isozyme Pattern을 조사(調査)한 결과(結果) 한국자생영지균(韓國自生靈芝菌)은 유전형질(遺傳形質)에 다양성(多樣性)을 보였다. 그중 Esterase Isozyme Pattern은 편각과 녹각간에 차이가 컸고 동(同) 계통(系統)간에는 높은 유사도(類似度)를 보여 계통분류(系統分類) 결과(結果)와 일치하였다.

  • 버섯에서 추출되는 생리활성물질얀 ${\beta}$-glucan은 탁월한 항암 효과를 갖는 물질이다. 특히 Agaricus blazei에 $\beta$-glucan이 많이 포함되어 있는 것으로 보고되어져 있다. 본 연구의 목적은 마이 크로웨이브를 사용하여 아가리쿠스버섯으로부터 ${\beta}$-glucan을 추 출하는 공정의 추출효율을 극대화하는 것으로, 다양한 추출시간 과 마이크로웨이브 출력을 이용하여 최적 운전조건을 결정하였 다. 최적 마이크로웨이브의 최적 출력은 200, 500, 650 watt의 경우에서 실험하여 결정하였다. 추출물질의 구조와 농도 분석은 nuclear magnetic resonance spectroscopy와 infrared spectroscopy 를 이용하여 수행하였다 본 실험 결과로 마이크로웨이브를 이 용한 추출의 다당류 수율이 전통적 인 열수추출방법보다 향상됨을 확인하였고, 소량의 용매와 짧은 추출 시간으로 향상된 수율을 얻을 수 있음을 알 수 있었다.
