Multi-locus molecular phylogenetic analysis reveals two new species of Amphichorda (Bionectriaceae, Hypocreales).

Amphichorda has been previously accepted as a member of the Cordycipitaceae and currently it is considered a member of the Bionectriaceae. The substrates of Amphichorda were complex and varied, being mainly animal faeces. This study reports two new species of Amphichorda from Yunnan Province in south-western China. Based on the five-gene (nr SSU , nr LSU , tef-1α , rpb1 and rpb2 ) sequence and ITS data phylogenetic analysis, two new species, namely A.excrementa and A.kunmingensis , are proposed and a detailed description of the new species is provided. Amphichordaexcrementa and A.kunmingensis were isolated from animal faeces in the park. The morphological characteristics of two novel species and seven known species in Amphichorda are also compared.
