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.

1997년부터 7월부터 2000년 8월까지 지리산국립공원, 변산반도국립공원, 모악산도립공원, 만뢰산, 위봉사, 운장산, 민주지산에서 채집하여 동정하였다. 그 결과 한국산 미기록종으로 확인 된 것은 관검은털먼지 (Amaurochaete tubulina), 쇠열매체먼지(Cribraria microcarpa), 빛 체먼지(Cribraria splendens), 흰색축먼지 (Diachea leucopodia), 이리장내먼지 (Enteridium lycoperdon), 노랑실먼지(Stemonitis flavogenita), 검은실먼지 (Stemonitis fusca)이었다. 이것들은 낙엽, 고목등 식물성 유기체에서 서식하고 있었고 이들에 대하여 한국보통명을 신칭 하였다.
