Characterization of Three Species of Sordariomycetes Isolated from Freshwater and Soil Samples in Korea

Abstract

During a survey of fungal diversity in the class Sordariomycetes, 3 fungal strains, CNUFC-KMHY6-1, CNUFC-MSW24-2-11, and CNUFC-GW2S-4 were isolated from soil and freshwater samples, respectively in Korea. The strains were analyzed both morphologically and phylogenetically on the basis of internal transcribed spacer and RNA polymerase II second largest subunit gene sequences. On the basis of their morphology and phylogeny, CNUFC-KMHY6-1, CNUFC-MSW24-2-11, and CNUFC-GW2S-4 isolates were identified as Arcopilus aureus, Memnoniella echinata, and Stachybotrys sansevieriae, respectively. To the best of our knowledge, Ar. aureus and M. echinata have not been previously recorded in Korea, and this is the first report of S. sansevieriae from freshwater niche.
