  • 본 연구에서는 국내 기수 환경의 물과 토양에서 균류의 다양성을 확인하기 위해 을숙도, 금강하구둑, 순천만습지, 대호방조제, 신두리사구 및 부남방조제 총 6지점의 현장조사 및 시료를 채집하였다. 현장에서 여과한 담수시료와 담수퇴적물로부터 곰팡이를 순수분리하여 PDA배지에 접종한 후 25℃에서 배양하였다. 기수역 시료에서 순수분리된 균주는 총 173균주로 ITS 부분을 분석하여 속 수준으로 동정하였다. 분리 동정된 균주를 다양성 지수를 이용하여 분석하였다. 분리된 균류는 Pleosporales, Eurotiales, Capnodiales, Hypocreales, Polyporales, Saccharomycetales, Agaricales, Glomerellales, Mucorales, Dothideales, Russulales, Xylariales, Sordariales, Myrmecridiales, Tubeufiales, Onygenales, Cantharellales, Amphisphaeriales 목에 속하며 Cladosporium속이 20%로 가장 우점하며, 그 다음은 Penicillium (19%), Fusarium (5%)의 순서로 많이 분포하였다. Sarocladium kiliense NNIBRFG3280와 Fusicolla merismoides NNIBRFG23708를 국내 기수환경에서 발굴하였으며, 이를 국내 미기록종으로 보고하고자 한다.

  • Recently, the Fusarium genus has been narrowed based upon phylogenetic analyses and a Fusarium-like clade was adopted. The few species of the Fusarium-like clade were moved to new, re-installed or existing genera or provisionally retained as "Fusarium." Only a limited number of reference strains and DNA marker sequences are available for this clade and not much is known about its actual species diversity. Here, we report six strains, preserved by the Belgian fungal culture collection BCCM/IHEM as a Fusarium species, that belong to the Fusarium-like clade. They showed a slow growth and produced pionnotes, typical morphological characteristics of many Fusarium-like species. Multilocus sequencing with comparative sequence analyses in GenBank and phylogenetic analyses, using reference sequences of type material, confirmed that they were indeed member of the Fusarium-like clade. One strain was identified as "Fusarium" ciliatum whereas another strain was identified as Fusicolla merismoides. The four remaining strains were shown to represent a unique phylogenetic lineage in the Fusarium-like clade and were also found morphologically distinct from other members of the Fusarium-like clade. Based upon phylogenetic considerations, a new genus, Pseudofusicolla gen. nov., and a new species, Pseudofusicolla belgica sp. nov., were installed for this lineage. A formal description is provided in this study. Additional sampling will be required to gather isolates other than the historical strains presented in the present study as well as to further reveal the actual species diversity in the Fusarium-like clade.
