[Objective] The aim of this study is to identify 6 marine fungi species by analyzing ITS nucleotide sequence, which had been primarily identified as penicillium based on morphological characteristics. [Method] The ITS regions of these species were cloned by molecule biology method and phylogenetic analyzed using ClustalX1.83 software. [Result] The ITS regions of these species were sequenced, and phylogenetic analysis between the yield sequences and the ITS sequences assessed in GenBank showed that the 6 strains all belonged to penicillium. [Conclusion] The present study suggests ITS sequence analysis could not be used as an only proof, but it is a very useful supplementary tool for the classification and identification of marine penicillium combined with morphological characteristics.
