Abstract

In our previous publication, we have tentatively concluded that our fungal specimen DL0038A and DL0038B are Cordyceps takaomontana. In order to further support the identification, we continued to analyse the nrSSU (nuclear ribosomal small subunit) and rpb1 (largest subunit of RNA polymerase II) genes, as well as combined analysis the nrLSU (largest subunit of RNA polymerase II) together with nrSSU and rpb2 genes on these specimens in order to support the morphological identification of those fungi. The results show that we successfully amplified all genes. Sequencing method was then adopted and proofread before molecular phylogenetic analysis was applied with reference sequences obtained from the publication of Sung et al. (2007). Once again, this analysis strongly supports the DL0038A and DL0038B specimen as Cordyceps takaomontana.
