Abstract

To investigate the diversity of aquatic fungi, we collected deposits of soil, plants, and plant litter from ponds and streams. NNIBRFG1552 was isolated from soil deposits and NNIBRFG3013 from plant deposits in Namsaengi-mot in Jeju, Korea in 2016; NNIBRFG5472 was isolated from plant litter in Bocheong-cheon, Boeun, Korea in 2018. Based on morphological characteristics and phylogenetic analysis using rDNA sequences of the internal transcribed spacer (ITS), NNIBRFG1552, NNIBRFG3013, and NNIBRFG5472 were identified as Filoporella exilis (100% similarity with KC834046), F. fistucella (99.8% with KC834047), and F. cf. annelidica (100% with KC834044), respectively. Furthermore, cultural and morphological characteristics were analyzed to confirm the molecular identification. No species of the genus Filosporella has yet been reported in Korea.

담수생태계에 서식하는 균류의 다양성을 조사하기 위해 연못과 하천에서 담수퇴적토, 수변식물, 담수침전식물체를 채집하였다. NNIBRFG1552와 NNIBRFG3013은 2016년 제주 남생이못에서 채집한 담수퇴적토와 수변식물에서 각각 분리되었고, NNIBRFG5472는 2018년 충북 보은의 보청천에서 채집한 담수침전식물체에서 분리되었다. 이들 3균주의 형태적 및 분자계통학적 특징을 바탕으로 동정한 결과 NNIBRFG1552, NNIBRFG3013, NNIBRFG5472는 각각Filoporella exilis (100%, KC834046), F. fistucella (99.8%, KC834047), F. cf. annelidica (100%, KC834044)로 확인되었다. 또한, 이들 3개 균주의 배양 및 형태학적 특성이 분자계통학적 분류와 일치되는 것을 확인하였다. Filosporella 속은 국내에서는 보고된 바 없으며 본 보고가 국내 최초이다.
