  • 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.

  • We have detected the slime mold, Diachea leucopodia (GNU06-10) in a strawberry greenhouse located in Sancheong-gun, Gyeongnam. Typical fruiting bodies had developed gregariously on the strawberry leaves, petioles, and plant debris on ground soil habitat, and also surprisingly on plastic pipes and a vinyl covering. Field samples were examined via stereomicroscopy, light microscopy, and SEM for the determination of morphological characteristics. Dark-brown to black spores formed gregariously within the stipitate cylindrical sporangium, and were covered by an iridescent peridium, which may be intact at maturity, or may have disintegrated. The upper portion of the peridium generally breaks up to expose the spores, whereas the lower portion was usually persistent. The results of energy dispersive X-ray spectrometer (EDS) analysis showed that lime was present in the stalk and columella but absent from the spores, capillitium, and peridium. The above characteristics confirm its taxonomic position in the genus Diachea. However, this genus is intermediate in character between the Physarales and Stemonitales of the Myxogastromycetidae. Hence, this genus had been classified as a member of the Stemonitales until the mid-1970's, on the basis of its iridescent peridium and noncalcareous capillitial system, similar to Comatricha of the Stemonitaceae. By way of contrast, emphasis on morphological characteristics, most notably the calcareous stalk and typical columella, places Diachea within the order Physarales. The presence of a phaneroplasmodium during the trophic stage and lime deposition in its sporophores, as was confirmed in this work, supported the inclusion of Diachea in the Physarales, and the noncalcareous capillitial system verified its identification as a member of the Didymiaceae. Further characteristics of the species D. leucopodia include the following: phaneroplasmodium, spore globose 7.5 ${\mu}m$ in diameter, very minutely roughened; sporangia $500{\mu}m\times1mm$, more or less cylindrical, gregarious, stalked 1.2mm; stalk and columella white.

  • Dissolution rate , periduium state, nutrient component and fatty acid composition of 5 species of natural pollen and 3 species of processed pollen were carried out for evaluation of quality. Natural pollens had average 11.5% of moistures, and had native peridium may be responsible for allergy. The average dissolution rate of natural pollens were low as 66.3%. One among 3 species of processed pollen was observed to have not peridium, resulted in higher dissolution rate. Major fatty acid of pollen was palmitic acid but content of oleic acid was lower than that of other plant seeds.

  • 경북, 전남, 충북, 충남 등 4개의 지역에서 채취된 식물뿌리주변의 토양에서 Glomales목의 내생균근균 중 포자과를 형성하는 Glomus속의 종들이 5종 발견되었다; G. clavisporum, G. liquidambaris, G. rubiforme, G. sinuosum, G. taiwanense. 이들의 포자과 및 포자의 형태적 특징들을 관찰하였다. G. clavisporum, G. liquidambaris G. taiwanense는 포자과피가 없는 포자과내에서 일정하게 배열된 곤봉모앙의 포자를 가진다는 점에서 유사하다. G. sinuosum은 두껍고 구불 구불한 형태의 포자과피를 갖는다는 점에서 다른 종과 구별된다. 또한 G. rubiforme은 포자과의 형태에 있어서 다른 4개의 종들과는 다른 형태를 나타냈다.

  • Farfugium japonicum is used in traditional medicine and as an edible herb in China and Korea. In July 2013, leaf spots were observed in F. japonicum seedlings at Ulleung Island, Gyeongsangbuk Province, Korea. Early symptoms on the leaf adaxial surface included roughly circular yellow spots that later developed brown, necrotic centers. The aecia were hypophyllous, cupulate, yellowish, $180{\sim}430{\mu}m$ in diameter, clustered, and erumpent with a peridium with a recurved margin. The aeciospores were globoid, $14{\sim}17{\times}13{\sim}16{\mu}m$, light yellow or colorless, and densely verrucose. The 28S rDNA sequence of the isolate was identical to each other and shared 99% identity with Puccinia caricis. This is the first report of rust caused by P. caricis in F. japonicum in Korea or elsewhere in the world.

  • 브랜스필드 동부 분지에서 얻은 길이 약 5m의 시추코어(A9-EB2)에서 채취된 44개의 시료로부터 총 41속 58종의 방산충이 감정되었으며, Antarctissa denticulata, A. longa, A. strelkovi, Lithomelissa setosa, Lithomitra lineata, Peridium longispinum와 Phormacantha hystrix 등이 우세종으로 이들이 총 산출량의 75%를 차지한다 시추코어에서 산출된 방산충 군집의 대부분은 긴 지질 시대를 나타내는 종들이며, Phaeodarian목의 Challengeriidae과에 속하는 Challengeron 속과 P개tocystis 속은 일반적으로 제4기에서 산출되므로 시추 퇴적물의 대략적인 지질 시대는 제4기(Pleistocene-Holocene)에 해당된다. 방산충 군집의 종조성은 Antarctissa strelkovi, A. denticulata, Cycladophora davisiana와 Larcopyle buetschlii등 전형적인 남극종(Circumpolar group)들이 다른 종들에 비해 상대적으로 다량 산출된다. 또한 연안 환경을 지시하는 Plectacantha oikiskos, Phomacantha hystrix와 원양 환경을 지시하는 Lithomelissa setosa가 함께 산출된다. 남극종의 산출과 Phomacantha-Plectacantha group이 Lithomelissa group의 산출량보다 많은 것으로 보아, 연구 지역은 남극순환수(Antarctic Circumpolar Current)나 벨링스하우젠해로부터 해류의 영향을 받은 연안 환경 지역이나 서쪽의 원양 환경인 웨델해로부터 브랜스필드 분지로 차가운 물이 유입되었음을 알 수 있다.

  • The tejocote (Crataegus spp.) is a tree considered to be native to Mexico. The aim of this study was to identify the causal agent of tejocote rust in the State of Puebla. Tejocote fruits were sampled in 2012 and 2013. The fungus was studied morphologically using light and scanning electron microscopy and molecularly using phylogenetic analysis of 18S and 28S rDNA genes. The fungus was identified as Gymnosporangium clavipes on tejocote fruits. To our knowledge, this is the first confirmed report of Gymnosporangium clavipes Cooke & Peck affecting Crataegus mexicana var. Chapeado and C. gracilior in Puebla Mexico.
